[0002] A thunderstorm is a local convective weather accompanied by lightning strikes and lightning. It occurs in strong cumulonimbus clouds and happens when the atmosphere is unstable. It is often accompanied by strong showers or heavy rains, and sometimes by hail and tornadoes. In the area where a thunderstorm occurs, if regional prevention and control are not carried out in a timely manner according to the characteristics of the thunderstorm area, it will pose a greater potential safety hazard.

[0045] A thunderstorm is a local convective weather accompanied by lightning strikes and lightning. It occurs in strong cumulonimbus clouds and occurs when the atmosphere is unstable. It is often accompanied by strong showers or heavy rains, sometimes accompanied by hail and tornadoes. In the area where a thunderstorm occurs, if the regional prevention and control are not carried out in a timely manner according to the characteristics of the thunderstorm area, it will cause greater potential safety hazards.

[0046] In the prior art, when a thunderstorm occurs in a thunderstorm area, the characteristics of the current thunderstorm area cannot be analyzed based on the collected thunderstorm data. Therefore, the convective data and water vapor data in the thunderstorm area cannot be analyzed according to the characteristics of the thunderstorm area, resulting in a low accuracy of the analysis results of the current regional thunderstorm impact, and further affecting the prevention and control effect in the thunderstorm area.

[0047] Based on this, the present application proposes the following technical solutions. For details, please refer to the following text:

[0048] In one embodiment, as Figure 1 shown, Figure 1 A structural schematic diagram of a regional thunderstorm impact analysis system provided by the embodiments of the present application; the present application provides a regional thunderstorm impact analysis system, which includes: a data acquisition module, a feature analysis module, an impact analysis module, a water vapor analysis module, and a convection analysis module.

[0049] The data acquisition module is used to determine the thunderstorm area to be analyzed, and after collecting the thunderstorm data of the thunderstorm area, send the thunderstorm data to the feature analysis module and the impact analysis module.

[0050] The feature analysis module is used to analyze the thunderstorm data received from the data acquisition module to obtain the cloud-to-ground flash distribution feature and the cloud-to-ground flash generation feature, form the thunderstorm area feature of the thunderstorm area, and send the thunderstorm area feature to the impact analysis module.

[0051] The impact analysis module is configured to generate a water vapor analysis signal and a convection analysis signal based on the thunderstorm data and the thunderstorm area characteristics after receiving the thunderstorm data sent by the data collection module and the thunderstorm area characteristics sent by the feature analysis module, and send the water vapor analysis signal to the water vapor analysis module and the convection analysis signal to the convection analysis module.

[0052] The water vapor analysis module is configured to analyze the water vapor analysis signal after receiving it, obtain a water vapor analysis result, and return the water vapor analysis result to the impact analysis module.

[0053] The convection analysis module is configured to analyze the convection analysis signal after receiving it, obtain a convection analysis result, and return the convection analysis result to the impact analysis module.

[0054] The impact analysis module is further configured to generate a thunderstorm impact analysis report for the thunderstorm area and a corresponding area protection report based on the water vapor analysis result returned by the water vapor analysis module and the convection analysis result returned by the convection analysis module.

[0055] In this embodiment, the regional thunderstorm impact analysis system may include a data collection module, a feature analysis module, an impact analysis module, a water vapor analysis module, and a convection analysis module. Among them, the data collection module is connected to the feature analysis module so that the feature analysis module can determine the thunderstorm area characteristics of the thunderstorm area based on the thunderstorm data obtained from the data collection module. In addition, the impact analysis module is respectively connected to each module, mainly responsible for obtaining the thunderstorm data of the thunderstorm area from the data collection module and the thunderstorm area characteristics from the feature analysis module, generating corresponding analysis signals based on the thunderstorm data and the thunderstorm area characteristics and sending them to each analysis module for analysis. Finally, the impact analysis module is also responsible for obtaining the analysis results of each analysis module, thereby generating a thunderstorm impact analysis report for the corresponding thunderstorm area and a corresponding area protection report and managing them. Thus, this application constitutes a complete regional thunderstorm impact analysis system.

[0056] Specifically, the impact analysis module generates a water vapor analysis signal and a convection analysis signal respectively based on the thunderstorm data and the thunderstorm area characteristics and sends them to the corresponding analysis modules. Here, the analysis modules refer to the water vapor analysis module and the convection analysis module. Each analysis module performs corresponding analysis functions. For example, the water vapor analysis module is mainly responsible for receiving the water vapor analysis signal and analyzing the water vapor analysis signal to obtain the water vapor development trend of the thunderstorm area, while the convection analysis module is mainly responsible for receiving the convection analysis signal and analyzing the convection analysis signal to obtain the thunderstorm volatility of the thunderstorm area.

[0057] Furthermore, after receiving the analysis results respectively returned by the water vapor analysis module and the convective analysis module, the impact analysis module can generate a thunderstorm impact analysis report for the thunderstorm area based on each analysis result for storage. Further still, the impact analysis module can also conduct a simple evaluation of the thunderstorm impact analysis report and generate a corresponding regional protection report according to the evaluation result. If the thunderstorm impact analysis report indicates that there are potential safety hazards in the thunderstorm area, the impact analysis module can issue a warning to the staff. The warning method can be through warning lights, alarms, warning pop-up screens, etc., or by sending the thunderstorm impact analysis report and the regional protection report to the staff's mobile devices via emails, text messages, etc., so that the staff can receive the warning in a timely manner and conduct targeted protection for the thunderstorm area according to the regional protection report.

[0058] In addition, after determining the thunderstorm area to be analyzed, the data acquisition module can collect the thunderstorm data of this thunderstorm area in real time. The thunderstorm data here includes but is not limited to the cloud flash density and cloud flash intensity corresponding to each position in the thunderstorm area during the current time period, the pulse discharge amount of each cloud flash, the number of cloud flash occurrences, the floating amount of the vector modulus of the water vapor amount, the increased amount of water vapor transport, the decreased amount of the atmospheric circulation velocity, and the duration of the constant atmospheric circulation velocity during the non-thunderstorm weather time period, etc. The specific duration of the current time period here can be set according to the analysis accuracy of the regional thunderstorm, and can be 10 minutes, 15 minutes, or 30 hours, etc. Also, when monitoring the thunderstorm data, monitoring means such as radar, satellite, and ground observation can be used, and there is no limit here.

[0059] In the above embodiments, the regional thunderstorm impact analysis system may include a data acquisition module, a feature analysis module, an impact analysis module, a water vapor analysis module, and a convection analysis module. Among them, the data acquisition module can, after determining the thunderstorm area to be analyzed, collect the thunderstorm data of the thunderstorm area in real time and send it to the feature analysis module and the impact analysis module, so that the feature analysis module analyzes the thunderstorm data to obtain the thunderstorm area characteristics of the thunderstorm area, and sends the thunderstorm area characteristics to the impact analysis module. Then, the impact analysis module can generate a water vapor analysis signal and a convection analysis signal based on the thunderstorm data and the thunderstorm area characteristics, and send the water vapor analysis signal to the water vapor analysis module and the convection analysis signal to the convection analysis module. Among them, the water vapor analysis module can analyze the water vapor analysis signal after receiving it to obtain the water vapor development trend of the thunderstorm area, while the convection analysis module can analyze the convection analysis signal after receiving it to obtain the thunderstorm floating property of the thunderstorm area. Finally, the impact analysis module can also generate a thunderstorm impact analysis report based on the received water vapor development trend and thunderstorm floating property, and then generate a regional protection report corresponding to the thunderstorm impact analysis report. Through the analysis of the thunderstorm data collected in real time in the thunderstorm area, the present application obtains the area characteristics of the thunderstorm area, so as to be able to analyze the convection data and water vapor data in the thunderstorm area according to the thunderstorm area characteristics, improve the accuracy of the impact analysis of the thunderstorm in the thunderstorm area, and then be able to formulate corresponding protection measures for the thunderstorm area and improve the prevention and control effect in the thunderstorm area.

[0060] In one embodiment, the process by which the feature analysis module analyzes the thunderstorm data to obtain the cloud-to-ground flash distribution characteristics may include: the feature analysis module obtains the cloud-to-ground flash density and cloud-to-ground flash intensity corresponding to each position in the thunderstorm area from the thunderstorm data, calculates the maximum density difference and average intensity difference of the thunderstorm area based on the cloud-to-ground flash density and cloud-to-ground flash intensity corresponding to each position, compares the maximum density difference with a preset density difference threshold and compares the average intensity difference with a preset intensity difference threshold, and marks the cloud-to-ground flash distribution characteristics of the thunderstorm area according to the comparison results.

[0061] In this embodiment, after receiving the thunderstorm data sent by the data acquisition module, the feature analysis module can obtain the cloud-to-ground flash density and cloud-to-ground flash intensity corresponding to each position in the thunderstorm area from the thunderstorm data. Then, the feature analysis module calculates the maximum density difference and average intensity difference of the thunderstorm area based on the cloud-to-ground flash density and cloud-to-ground flash intensity, so as to compare the maximum density difference with a preset density difference threshold and compare the average intensity difference with a preset intensity difference threshold to obtain the comparison results. Finally, the cloud-to-ground flash distribution characteristics of the thunderstorm area are marked according to the comparison results.

[0062] It can be understood that the cloud-to-ground flash density here refers to the number of cloud-to-ground flashes within a certain time and space range, and the cloud-to-ground flash intensity refers to the average current intensity of cloud-to-ground flashes. In a thunderstorm area, the cloud-to-ground flash density and the cloud-to-ground flash intensity can be used as important indicators to reflect the intensity and activity level of thunderstorm activities in the thunderstorm area. After obtaining the cloud-to-ground flash density and the cloud-to-ground flash intensity corresponding to each position within the thunderstorm area, the present application can calculate the differences in cloud-to-ground flash density and cloud-to-ground flash intensity between adjacent positions respectively, and use the maximum value of the differences in cloud-to-ground flash density as the maximum density difference, and use the average value of the differences in cloud-to-ground flash intensity as the average intensity difference.

[0063] Specifically, the staff can set the preset density difference threshold and the preset intensity difference threshold for the thunderstorm area according to the terrain distribution of each position in the thunderstorm area and store them in the feature analysis module. When the feature analysis module needs to mark the cloud-to-ground flash distribution characteristics of the thunderstorm area, it can obtain the preset density difference threshold and the preset intensity difference threshold corresponding to the thunderstorm area, so as to compare the maximum density difference with the preset density difference threshold and compare the average intensity difference with the preset intensity difference threshold to obtain the comparison result.

[0064] In one embodiment, the cloud-to-ground flash distribution characteristics of the thunderstorm area include non-uniformity and uniformity; the process of the feature analysis module marking the cloud-to-ground flash distribution characteristics of the thunderstorm area according to the comparison result may include: when the feature analysis module confirms that the maximum density difference exceeds the preset density difference threshold or the average intensity difference exceeds the preset intensity difference threshold, it marks the cloud-to-ground flash distribution characteristics of the thunderstorm area as non-uniformity; when the feature analysis module confirms that the maximum density difference does not exceed the preset density difference threshold and the average intensity difference exceeds the preset intensity difference threshold, it marks the cloud-to-ground flash distribution characteristics of the thunderstorm area as uniformity.

[0065] In this embodiment, the feature analysis module can mark the cloud-to-ground flash distribution characteristics of the thunderstorm area as non-uniformity or uniformity according to the comparison result. Among them, when the maximum density difference of the thunderstorm area exceeds the preset density difference threshold or the average intensity difference exceeds the preset intensity difference threshold, the cloud-to-ground flash distribution characteristics of the thunderstorm area are non-uniformity; when the maximum density difference of the thunderstorm area does not exceed the preset density difference threshold and the average intensity difference exceeds the preset intensity difference threshold, the cloud-to-ground flash distribution characteristics of the thunderstorm area are uniformity.

[0066] Schematically, as Figure 2 shown, Figure 2 is a schematic flowchart of the process for marking the cloud-to-ground flash distribution characteristics provided by the embodiment of the present application; Figure 2Among them, the feature analysis module determines whether the comparison result is that the maximum density difference in the thunderstorm area does not exceed the preset density difference threshold and the average intensity difference does not exceed the preset intensity difference threshold; if so, it marks the cloud-to-ground flash distribution feature of the thunderstorm area as uniformity; if not, it marks the cloud-to-ground flash distribution feature of the thunderstorm area as non-uniformity. It should be noted that the maximum density difference and the average intensity difference can reflect the distribution law and change trend of thunderstorm activities. When the cloud-to-ground flash distribution feature of the thunderstorm area is uniformity, it indicates that the thunderstorm activities in this thunderstorm area are relatively stable or in the middle stage of the active period, and at this time, the impact of thunderstorm activities on the thunderstorm area is small; when the cloud-to-ground flash distribution feature of the thunderstorm area is non-uniformity, it indicates that the intensity of thunderstorm activities in this thunderstorm area is relatively large or in a certain stage of the active period, and the impact on the thunderstorm area is large. At this time, some corresponding prevention or early warning measures can be taken for thunderstorm activities.

[0067] In one embodiment, the process by which the feature analysis module analyzes the thunderstorm data to obtain the cloud-to-ground flash generation features may include: the feature analysis module obtains the pulse discharge amount and the number of cloud-to-ground flashes generated in each cloud-to-ground flash in the thunderstorm area from the thunderstorm data, and calculates the maximum discharge amount difference and the instantaneous cloud-to-ground flash frequency of the thunderstorm area based on the pulse discharge amount and the number of cloud-to-ground flashes generated in each cloud-to-ground flash, and compares the maximum discharge amount difference with the preset discharge amount difference threshold and compares the instantaneous cloud-to-ground flash frequency with the preset frequency threshold, and marks the cloud-to-ground flash generation features of the thunderstorm area according to the comparison result.

[0068] In this embodiment, after receiving the thunderstorm data sent by the data acquisition module, the feature analysis module can also obtain the pulse discharge amount and the number of cloud-to-ground flashes generated in each cloud-to-ground flash in the thunderstorm area from the thunderstorm data. Then, the feature analysis module calculates the maximum discharge amount difference and the instantaneous cloud-to-ground flash frequency of the thunderstorm area based on the pulse discharge amount and the number of cloud-to-ground flashes generated, so as to compare the maximum discharge amount difference with the preset discharge amount difference threshold and compare the instantaneous cloud-to-ground flash frequency with the preset frequency threshold to obtain the comparison result. Finally, the cloud-to-ground flash generation features of the thunderstorm area are marked according to this comparison result.

[0069] It can be understood that the pulse discharge amount here refers to the electric energy released when a cloud-to-ground flash occurs, and the number of cloud-to-ground flashes generated refers to the number of cloud-to-ground flashes within a certain time and space range. In the thunderstorm area, the pulse discharge amount and the number of cloud-to-ground flashes generated can be important indicators reflecting the intensity and activity degree of thunderstorm activities in this thunderstorm area. After obtaining the pulse discharge amount and the number of cloud-to-ground flashes generated in each cloud-to-ground flash in the thunderstorm area in this application, the difference in the pulse discharge amount between adjacent cloud-to-ground flashes can be calculated, and the maximum value of the pulse discharge amount difference is used as the maximum discharge amount difference, and the number of cloud-to-ground flashes generated is divided by the length of the current time period to obtain the instantaneous cloud-to-ground flash frequency.

[0070] Specifically, the staff can set the preset discharge amount difference threshold and the preset frequency threshold of the thunderstorm area according to the terrain distribution of each position in the thunderstorm area and store them in the feature analysis module. When the feature analysis module needs to mark the cloud-to-ground flash generation characteristics of the thunderstorm area, it can obtain the corresponding preset discharge amount threshold and preset frequency threshold of the thunderstorm area, so as to compare the maximum discharge amount difference with the preset discharge amount difference threshold and compare the cloud-to-ground flash instantaneous frequency with the preset frequency threshold to obtain the comparison result.

[0071] In one embodiment, the cloud-to-ground flash generation characteristics of the thunderstorm area include suddenness and non-suddenness; the process of marking the cloud-to-ground flash generation characteristics of the thunderstorm area according to the comparison result may include: when the feature analysis module confirms that the maximum discharge amount difference exceeds the preset discharge amount difference threshold or the cloud-to-ground flash instantaneous frequency exceeds the preset frequency threshold, it marks the cloud-to-ground flash generation characteristics of the thunderstorm area as sudden; when the feature analysis module confirms that the maximum discharge amount difference does not exceed the preset discharge amount difference threshold and the cloud-to-ground flash instantaneous frequency does not exceed the preset frequency threshold, it marks the cloud-to-ground flash generation characteristics of the thunderstorm area as non-sudden.

[0072] In this embodiment, the feature analysis module can also mark the cloud-to-ground flash generation characteristics of the thunderstorm area as sudden and non-sudden according to the comparison result. Among them, when the maximum discharge amount difference of the thunderstorm area exceeds the preset discharge amount difference threshold or the cloud-to-ground flash instantaneous frequency exceeds the preset frequency threshold, the cloud-to-ground flash generation characteristics of the thunderstorm area are sudden; when the maximum discharge amount difference of the thunderstorm area does not exceed the preset discharge amount difference threshold and the cloud-to-ground flash instantaneous frequency does not exceed the preset frequency threshold, the cloud-to-ground flash generation characteristics of the thunderstorm area are non-sudden.

[0073] Schematically, as Figure 3 shown, Figure 3 is a schematic flowchart of the cloud-to-ground flash generation characteristic marking process provided by the embodiment of the present application; Figure 3 In it, the feature analysis module judges whether the comparison result is that the maximum discharge amount difference of the thunderstorm area does not exceed the preset discharge amount difference threshold and the cloud-to-ground flash instantaneous frequency does not exceed the preset frequency threshold; if so, it marks the cloud-to-ground flash generation characteristics of the thunderstorm area as non-sudden; if not, it marks the cloud-to-ground flash generation characteristics of the thunderstorm area as sudden. It should be noted that the maximum discharge amount difference and the cloud-to-ground flash instantaneous frequency can reflect the intensity change and activity degree of thunderstorm activities. When the cloud-to-ground flash generation characteristics of the thunderstorm area are non-sudden, it means that the cloud-to-ground flash generation in the thunderstorm area is relatively stable and there is no sudden change in discharge amount and frequency; when the cloud-to-ground flash generation characteristics of the thunderstorm area are sudden, it means that the generation of cloud-to-ground flashes in the thunderstorm area has increased sharply, which will have a greater negative impact on the thunderstorm area. At this time, some corresponding prevention or early warning measures can be taken for thunderstorm activities.

[0074] Therefore, after the feature analysis module of the present application marks the lightning flash distribution characteristics and lightning flash generation characteristics of the thunderstorm area respectively, the thunderstorm area characteristics can be obtained. At this time, the thunderstorm area characteristics can include uniform and sudden areas, uniform and non-sudden areas, non-uniform and sudden areas, and non-uniform and non-sudden areas. After obtaining the thunderstorm area characteristics, the thunderstorm data of the thunderstorm area can be further analyzed based on the thunderstorm area characteristics to improve the accuracy of the analysis results, so that corresponding thunderstorm warnings and prevention and control can be carried out for the analysis results of different types of areas.

[0075] In one embodiment, the process of the impact analysis module for generating a water vapor analysis signal and a convection analysis signal according to the thunderstorm data and the thunderstorm area characteristics may include: the impact analysis module obtains the floating amount of the vector modulus value of the water vapor amount, the increase amount of the water vapor amount transportation, the decrease amount of the atmospheric circulation velocity, and the constant duration of the atmospheric circulation velocity in the non-thunderstorm weather period in the thunderstorm data, and converts the floating amount and the increase amount into a water vapor analysis signal and converts the decrease amount and the constant duration into a convection analysis signal based on the thunderstorm area characteristics.

[0076] In this embodiment, after receiving the thunderstorm data sent by the data acquisition module and the thunderstorm area characteristics sent by the feature analysis module, the impact analysis module can convert the floating amount of the vector modulus value of the water vapor amount and the increase amount of the water vapor amount transportation in the thunderstorm data into a water vapor analysis signal based on the thunderstorm area characteristics, and convert the decrease amount of the atmospheric circulation velocity and the constant duration of the atmospheric circulation velocity in the non-thunderstorm weather period in the thunderstorm data into a convection analysis signal based on the thunderstorm area characteristics.

[0077] It can be understood that the floating amount here refers to the change range of the water vapor amount in the current time period. When the floating amount of the vector modulus value of the water vapor amount is large, it indicates an increase in the probability of precipitation, which may cause natural disasters such as floods, mountain torrents, and debris flows; the increase amount refers to the amount of increase in the transportation of water vapor in the atmosphere in the current time period. The increase amount of the water vapor amount transportation can reflect the intensity and activity of the water vapor transportation in the atmosphere and is closely related to the floating amount of the vector modulus value of the water vapor amount; the decrease amount refers to the degree of decrease in the atmospheric circulation velocity in the current time period. The decrease amount of the atmospheric circulation velocity affects the stability and change degree of the meteorological conditions, thus affecting the occurrence and impact of thunderstorm weather; and the constant duration refers to the duration of non-thunderstorm weather in the current time period. Since the stability and change degree of the atmospheric circulation affect the formation and development of thunderstorm weather, the constant duration affects the occurrence of thunderstorm activities. Therefore, when analyzing the impact of the thunderstorm area's fiery activities, the present application can comprehensively consider various factors such as the floating amount, the increase amount, the decrease amount, and the constant duration to improve the accuracy and reliability of the analysis results.

[0078] In one embodiment, the process of the water vapor analysis module analyzing the water vapor analysis signal may include: the water vapor analysis module obtaining the floating amount of the vector modulus of the water vapor amount carried in the water vapor analysis signal and the increased amount of the water vapor amount transported, and comparing the floating amount with a preset floating amount threshold and comparing the increased amount with a preset increased amount threshold, and determining the water vapor development trend of the thunderstorm area according to the comparison result.

[0079] In this embodiment, after receiving the water vapor analysis signal sent by the impact analysis system, the water vapor analysis module can analyze the water vapor analysis signal, so as to obtain the floating amount of the vector modulus of the water vapor amount carried in the water vapor analysis signal and the increased amount of the water vapor amount transported. Then, it can determine the preset floating amount threshold corresponding to the floating amount and the preset increased amount threshold corresponding to the increased amount, so as to compare the floating amount with the preset floating amount threshold and compare the increased amount with the preset increased amount threshold to obtain a comparison result. Finally, it determines the water vapor development trend of the thunderstorm area according to the comparison result.

[0080] It can be understood that the staff can set the corresponding preset floating amount threshold and preset increased amount threshold according to the terrain distribution of each position in the thunderstorm area and store them in the water vapor analysis module. When analyzing the water vapor analysis signal, the water vapor analysis module can first determine the preset floating amount threshold and preset increased amount threshold corresponding to the thunderstorm area, so as to compare the floating amount with the preset floating amount threshold and compare the increased amount with the preset increased amount threshold to obtain a comparison result.

[0081] In one embodiment, the process of the water vapor analysis module determining the water vapor development trend of the thunderstorm area according to the comparison result may include: when the water vapor analysis module determines that the floating amount exceeds the preset floating amount threshold or the increased amount exceeds the preset increased amount threshold, it determines that the water vapor development trend of the thunderstorm area is an increasing trend; when the water vapor analysis module determines that the floating amount does not exceed the preset floating amount threshold and the increased amount does not exceed the preset increased amount threshold, it determines that the water vapor development trend of the thunderstorm area is a decreasing trend.

[0082] In this embodiment, the water vapor analysis module can determine the water vapor development trend of the thunderstorm area as an increasing trend or a decreasing trend according to the comparison result. Among them, when the floating amount of the thunderstorm area exceeds the preset floating amount threshold or the increased amount exceeds the preset increased amount threshold, the water vapor development trend of the thunderstorm area is an increasing trend; when the floating amount of the thunderstorm area does not exceed the preset floating amount threshold and the increased amount does not exceed the preset increased amount threshold, the water vapor development trend of the thunderstorm area is a decreasing trend.

[0083] Schematically, as Figure 4 shown, Figure 4It is a schematic flowchart of the analysis process of the water vapor analysis module provided by the embodiment of the present application; Figure 4 In it, the water vapor analysis module determines whether the comparison result is that the floating amount does not exceed the preset floating amount threshold and the increase amount does not exceed the preset increase amount threshold; if so, it determines that the water vapor development trend in the thunderstorm area is a decreasing trend; if not, it determines that the water vapor development trend in the thunderstorm area is an increasing trend. It should be noted that the floating amount of the vector modulus value of the water vapor amount and the increase amount of the water vapor transport have different effects on the water vapor change in the thunderstorm area. Therefore, only when both the floating value and the increase amount do not exceed the threshold can it be indicated that the water vapor development trend in the thunderstorm area is a decreasing trend, the water vapor content is small or in a certain stage of decline, and at this time, periodic protection can be carried out on the thunderstorm area; on the contrary, when the water vapor development trend in the thunderstorm area is a decreasing trend, continuous protection can be carried out on the thunderstorm area.

[0084] In one embodiment, the process of the convection analysis module for analyzing the convection analysis signal may include: the convection analysis module obtains the decrease amount of the atmospheric circulation flow velocity carried in the convection analysis signal and the constant duration of the atmospheric circulation flow velocity, and compares the decrease amount with the preset decrease amount threshold and compares the constant duration with the preset duration threshold, and determines the thunderstorm floating property in the thunderstorm area according to the comparison result.

[0085] In this embodiment, after receiving the convection analysis signal sent by the influence analysis module, the convection analysis module can analyze the convection analysis signal, so as to obtain the decrease amount of the atmospheric circulation flow velocity carried in the convection analysis module and the constant duration of the atmospheric circulation flow velocity during the non-thunderstorm weather period. Then, it can determine the preset decrease amount threshold corresponding to the decrease amount and the preset duration threshold corresponding to the constant duration, so as to compare the decrease amount with the preset decrease amount threshold and compare the constant duration with the preset duration threshold to obtain the comparison result, and finally determine the thunderstorm floating property in the thunderstorm area according to the comparison result.

[0086] It can be understood that the staff can set the corresponding preset decrease amount threshold and preset duration threshold according to the terrain distribution of each position in the thunderstorm area and store them in the convection analysis module. When the convection analysis module analyzes the convection analysis signal, it can first determine the preset decrease amount threshold and preset duration threshold corresponding to the thunderstorm area, so as to compare the decrease amount with the preset decrease amount threshold and compare the constant duration with the preset duration threshold to obtain the comparison result.

[0087] In one embodiment, the process by which the convective analysis module determines the convective volatility of the thunderstorm area based on the comparison result may include: when the convective analysis module determines that the reduction amount exceeds a preset reduction amount threshold or the constant duration does not exceed a preset duration threshold, it determines that the convective volatility of the thunderstorm area is low volatility; when the convective analysis module determines that the reduction amount does not exceed the preset reduction amount threshold and the constant duration exceeds the preset duration threshold, it determines that the convective volatility of the thunderstorm area is high volatility.

[0088] In this embodiment, the convective analysis module may determine the convective volatility of the thunderstorm area as low volatility or high volatility according to the comparison result. Among them, when the reduction amount in the thunderstorm area exceeds the preset reduction amount threshold or the constant duration does not exceed the preset duration threshold, the convective volatility of the thunderstorm area is low volatility. When the reduction amount in the thunderstorm area does not exceed the preset reduction amount threshold and the constant duration exceeds the preset duration threshold, the convective volatility of the thunderstorm area is low volatility.

[0089] Schematically, as Figure 5 shown, Figure 5 is a schematic flowchart of the analysis process of the convective analysis module provided by the embodiment of the present application; Figure 5 In it, the convective analysis module determines whether the comparison result is that the reduction amount does not exceed the preset reduction amount threshold and the constant duration exceeds the preset duration threshold; if so, it determines that the convective volatility of the thunderstorm area is high volatility; if not, it determines that the convective volatility of the thunderstorm area is low volatility. It should be noted that the convective volatility of the thunderstorm area can reflect the distribution law and change trend of thunderstorm activities in the thunderstorm area. When the convective volatility is high volatility, it means that the change of thunderstorm activities in the thunderstorm area is relatively fast and intense. Therefore, real-time protection can be carried out on the cloud layer position in the thunderstorm area; when the convective volatility is low volatility, it means that the thunderstorm activities in the thunderstorm area are relatively stable, with small changes and fluctuations. At this time, targeted prevention and control can be carried out on the cloud layer position with thunderstorm fluctuations in the thunderstorm area.
