Description

Technical Field

[0001] This invention relates to the field of artificial rain enhancement technology, and in particular to a method and system for collecting, processing, and analyzing artificial weather modification data to determine rain enhancement potential. Background Technology

[0002] Current methods for assessing the catalytic potential of cloud enhancement before artificial rainmaking operations have several shortcomings. Regarding data collection, existing methods fail to accurately reflect the actual cloud development due to the lack of detailed data collection on the duration and volume changes of different cloud growth stages. In terms of assessment indicators, there is a lack of comprehensive indicators that consider multiple factors, failing to fully account for the complexity and variability of cloud development and thus not accurately reflecting the catalytic potential and rainmaking effect of clouds at different stages. Furthermore, existing assessment methods do not precisely quantify the specific impact of the duration and volume changes of each growth stage on the rainmaking catalytic potential of cloud regions with high catalytic efficiency, nor do they address the intrinsic correlation between key factors such as supercooled water content and catalytic potential. This limits the accuracy and reliability of the rainmaking catalytic potential assessment, leading to discrepancies between the assessment results and actual cloud conditions, thereby affecting the effectiveness of artificial rainmaking operations. Summary of the Invention

[0019] Furthermore, based on the volume ratio of rain enhancement catalytic potential at different times, the growth stages of the rain enhancement catalytic target area are determined, and cloud regions with high catalytic efficiency are selected from the rain enhancement catalytic target area for regional volume calculation, including the following steps:

[0031] Furthermore, based on cloud development stability and cloud catalytic potential, assessing cloud-based rain enhancement catalytic potential and generating a cloud-based rain enhancement catalytic operation report includes the following steps:

[0032] If the cloud's catalytic potential is low and its development stability is moderate or above, then the cloud is deemed suitable for rain enhancement catalytic operations; if the cloud's catalytic potential is low and its development stability is low or below, then the cloud is deemed unsuitable for rain enhancement catalytic operations, and a cloud rain enhancement catalytic operation report will be generated.

It should be noted that, in the absence of conflict, the following embodiments and features in the embodiments can be combined with each other. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0063] Example 1

[0064] like Figure 1 As shown, a method for collecting, processing, and analyzing artificial weather modification data to determine rainfall potential includes the following steps:

[0065] S101. Perform feature fusion on cloud radar data and cloud temperature data to construct a cloud temperature-thickness-echo intensity distribution map, and perform image segmentation to remove image areas smaller than the cloud thickness threshold.

[0066] Cloud radar echo data and cloud temperature data are acquired based on time series data. Cloud echo feature extraction is performed on the radar echo data to obtain cloud echo features, including cloud echo morphology and intensity characteristics. It should be noted that the cloud echo morphology features reveal the cloud thickness distribution, which is subsequently compared to a set cloud thickness threshold, removing data below this threshold. Cloud temperature distribution features are extracted from the cloud temperature data to obtain cloud temperature distribution characteristics. The cloud echo features and cloud temperature distribution characteristics are then fused to construct a cloud temperature-thickness-echo intensity distribution map. This map visually presents the cloud thickness and shape, echo intensity, and temperature distribution. To reduce data processing load, a cloud thickness threshold can be set to perform image segmentation on the cloud temperature-thickness-echo intensity distribution map, removing image areas smaller than the cloud thickness threshold and retaining areas greater than or equal to it. Optionally, based on the temperature distribution characteristics of the cloud layer, it can be determined whether the cloud layer is a cold cloud layer or a warm cloud layer to determine the type of catalyst to be selected, and the cloud layer can be labeled. The labeling process includes labeling the cloud layer temperature type and labeling the catalyst selection type.

[0067] The process of fusing features from cloud radar data and cloud temperature data to construct a cloud temperature-thickness-echo intensity distribution map, and then performing image cropping to remove image regions smaller than the cloud thickness threshold, includes the following steps:

[0068] Cloud echo features are obtained by extracting cloud echo features from cloud radar echo data. The cloud echo features include cloud echo morphology features and cloud echo intensity features.

[0069] The cloud temperature distribution characteristics are extracted from the cloud temperature data to obtain the cloud temperature distribution characteristics and determine the cloud temperature type.

[0070] The cloud echo characteristics and cloud temperature distribution characteristics are fused to construct a cloud temperature-thickness-echo intensity distribution map.

[0071] By setting a cloud thickness threshold, the cloud temperature-thickness-echo intensity distribution map is processed to remove image areas smaller than the cloud thickness threshold and retain image areas greater than or equal to the cloud thickness threshold.

[0072] For example, if the cloud thickness in a region is less than 2 km, effective rainfall is unlikely to occur even after catalysis. After fusing cloud echo characteristics and cloud temperature distribution characteristics to construct a cloud temperature-thickness-echo intensity distribution map, a cloud thickness threshold of 2 km is set. Image areas with a thickness less than 2 km are cut off, retaining only areas with a thickness greater than or equal to the threshold. This not only reduces data processing load but also accurately identifies cloud areas that meet the basic conditions for rain enhancement. It should be noted that the cloud thickness threshold can be set according to actual conditions. This embodiment is merely an example, and any image segmentation processing of the cloud temperature-thickness-echo intensity distribution map using a cloud thickness threshold falls within the scope of this invention.

[0073] S102. Select the target area for rain enhancement catalysis from the cut cloud temperature-thickness-echo intensity distribution map by setting the catalytic echo intensity threshold range, and perform rain enhancement catalytic potential volume ratio calculation.

[0074] The volume of the cloud region is calculated from the segmented cloud temperature-thickness-echo intensity distribution map to obtain the volume of the rain enhancement development area. A catalytic echo intensity threshold range is set based on the cloud temperature type to screen suitable cloud regions for rain enhancement catalysis operations. The volume of the cloud region within this catalytic echo intensity threshold range is then calculated to obtain the volume of the rain enhancement catalysis target area. The rain enhancement catalysis potential volume ratio is calculated by dividing the volume of the rain enhancement development area by the volume of the rain enhancement development area, and this ratio is saved to the rain enhancement potential database. The rain enhancement catalysis potential volume ratio can be used to measure the current rain enhancement potential development level of the cloud region.

[0075] The process of selecting rain enhancement catalysis target areas from the cut cloud temperature-thickness-echo intensity distribution map by setting the catalytic echo intensity threshold range and calculating the volume ratio of rain enhancement catalysis potential includes the following steps:

[0076] The volume of the rain enhancement development area is obtained by performing volume calculation on the cut cloud temperature-thickness-echo intensity distribution map.

[0077] The catalytic echo intensity threshold range is set based on cloud temperature type, and the volume of the cloud area within the catalytic echo intensity threshold range is calculated to obtain the volume of the rain enhancement catalytic target area.

[0078] The volume of the target area for rain enhancement and the volume of the development area for rain enhancement are compared to obtain the volume ratio of the potential rain enhancement volume, and then saved to the rain enhancement potential database.

[0079] For example, if the cloud temperature type is a cold cloud, the catalytic echo intensity threshold range for this type of cold cloud can be set to 15dBZ-35dBZ. Volume calculations are performed on the cloud region within this 15dBZ-35dBZ range to obtain the volume of the target area for rain enhancement. The volume of the target area is then divided by the volume of the rain enhancement development area to obtain the volume ratio of the rain enhancement potential for this type of cold cloud. Conversely, if the cloud temperature type is a warm cloud, the catalytic echo intensity threshold range for this type of warm cloud can be set to 20dBZ-40dBZ. Volume calculations are performed on the cloud region within this 20dBZ-40dBZ range to obtain the volume of the target area for rain enhancement. The volume of the target area is then divided by the volume of the rain enhancement development area to obtain the volume ratio of the rain enhancement potential for this type of warm cloud.

[0080] S103. Based on the volume ratio of rain enhancement catalytic potential at different times, determine the growth stages of the rain enhancement catalytic target area, and select cloud areas with high catalytic efficiency from the rain enhancement catalytic target area for regional volume calculation.

[0081] Based on the volume ratio of rain enhancement catalytic potential at different times in the rain enhancement potential database, a change curve of the volume ratio of rain enhancement catalytic potential is constructed. The slope of this curve allows for a direct assessment of the volume growth rate of the target area for rain enhancement in the cloud layer. The curve is then divided into growth stages based on the slope, resulting in different growth stages for the target area. These stages include slow growth, rapid growth, and deceleration. By setting a cloud echo intensity threshold range, cloud regions within this range are identified. High-efficiency cloud regions are then selected, and their volume is calculated to determine the volume of high-efficiency cloud regions at each growth stage. By analyzing the volume of these high-efficiency cloud regions at each growth stage, the rain enhancement catalytic effect at different growth stages can be quantitatively evaluated, accurately determining which growth stage yields the most significant catalytic effect.

[0082] The growth stages of the rain enhancement catalytic target area are determined based on the volume ratio of rain enhancement catalytic potential at different times, and cloud areas with high catalytic efficiency are selected from the rain enhancement catalytic target area for regional volume calculation, including the following steps:

[0083] A curve showing the change in the volume ratio of rain enhancement catalytic potential was constructed based on the volume ratio of rain enhancement catalytic potential at different times.

[0084] The constructed rain enhancement catalytic potential volume ratio change curve was divided into rain enhancement catalytic region growth stages to obtain each growth stage of the rain enhancement catalytic target region;

[0085] Based on the cloud echo intensity threshold range, cloud regions with high catalytic efficiency are screened from the rain enhancement catalysis target area, and the volume of cloud regions with high catalytic efficiency is calculated to obtain the volume of cloud regions with high catalytic efficiency at each growth stage of the rain enhancement catalysis target area.

[0086] For example, according to the rain enhancement potential database , , ... The volume ratio of the rain enhancement catalytic potential at any given time was used to construct a curve showing its change. This curve was then divided into growth stages within the rain enhancement catalytic region to obtain the growth stages of the target region for rain enhancement in that cloud layer. The durations of the slow growth rate stage, the fast growth rate stage, and the deceleration growth rate stage were also statistically analyzed. Based on a set cloud echo intensity threshold range of 20dBZ-30dBZ, cloud regions within this range were selected as having high catalytic efficiency. The volume of these high-efficiency cloud regions was then calculated to obtain their overall volume.

[0087] S104. Based on the duration of each growth stage and the volume increase of each growth stage in cloud regions with high catalytic efficiency, as well as the supercooled water content, determine the degree of cloud rain enhancement catalytic potential.

[0088] By statistically analyzing the duration of each growth stage in cloud regions with high catalytic efficiency within the target area for rain enhancement, and the volume increase during each growth stage, the dynamic development of these cloud regions can be accurately determined. This allows for the identification of the optimal time for catalyst deployment and improvement of rain enhancement operations. Specifically, the duration of each growth stage in high-efficiency cloud regions reflects the cloud's potential for stable development, while the volume increase during slow and decelerating growth stages reflects the cloud's capacity for sustained water vapor supply.

[0089] The determination of cloud rain enhancement catalytic potential, based on the duration of each growth stage, the volume increase during each growth stage, and the supercooled water content in cloud regions with high catalytic efficiency, includes the following steps:

[0090] Based on the duration of each growth stage and the volume increase during each growth stage in cloud regions with high catalytic efficiency, the stability of cloud development is determined, and its expression is as follows:

[0091]

[0092] in, For the stability of cloud development, The duration of the slow growth rate phase. The duration of the rapid growth phase, The duration of the growth rate slowdown phase. The volume of cloud regions with high catalytic efficiency during the slow growth phase. The volume of cloud regions with high catalytic efficiency increases during the rapid growth phase. The volume of the cloud region with high catalytic efficiency increases during the slowdown phase of growth rate;

[0093] Based on the volume of the high-catalytic-efficiency cloud region and the supercooled water content during the rapid growth phase, the cloud catalytic potential is determined, and its expression is as follows:

[0094]

[0095] in, For cloud catalytic potential, The volume of cloud regions with high catalytic efficiency increases during the rapid growth phase. The duration of the rapid growth phase, air density, The content of supercooled water;

[0096] Based on cloud development stability and cloud catalytic potential, the cloud rain enhancement catalytic potential is assessed and a cloud rain enhancement catalytic operation report is generated.

[0097] Based on cloud development stability and cloud catalytic potential, assessing cloud rain enhancement catalytic potential and generating a cloud rain enhancement catalytic operation report includes the following steps:

[0098] If the cloud's catalytic potential is low and its development stability is moderate or above, then the cloud is deemed suitable for rain enhancement catalytic operations; if the cloud's catalytic potential is low and its development stability is low or below, then the cloud is deemed unsuitable for rain enhancement catalytic operations, and a cloud rain enhancement catalytic operation report will be generated.

[0099] If the cloud's catalytic potential is high and its development stability is low or above, then the cloud is deemed suitable for rain enhancement catalytic operations. If the cloud's catalytic potential is high and its development stability is below low, then the cloud is deemed unsuitable for rain enhancement catalytic operations, and a cloud rain enhancement catalytic operation report will be generated.

[0100] For example, cloud development stability A value greater than or equal to 0.9 indicates a high degree of stability in cloud development. A value less than 0.9 and greater than or equal to 0.8 indicates a moderate degree of cloud development stability. A value less than 0.8 and greater than or equal to 0.7 indicates low cloud development stability. A value less than 0.7 indicates that the cloud layer is unsuitable for rain enhancement catalysis. Cloud catalysis potential. A value less than or equal to 1 indicates a low degree of cloud catalytic potential. A value greater than 1 and less than 2.5 indicates high catalytic potential of clouds. A value greater than 2.5 indicates that the material is unsuitable for rain enhancement catalysis operations.
