[0048] In reality, the degree of physical and economic impact of weather on different scenarios, industries, spaces, and times varies significantly. Different scenarios and industries have different resilience to weather changes, which determines that they have different requirements for the accuracy of weather forecasts when responding to weather changes. How to achieve efficient weather change response results based on the actual needs of different scenarios and industries and the technical level of available weather forecast data is a very important technical issue, and the technical method to solve this technical problem can be defined as a data processing method for weather management engineering.
[0049] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0050] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0051] like Figure 1 As shown, the present invention provides a data processing method for weather management engineering, comprising:
[0052] Step 101: Standardize the weather forecast data and establish a weather forecast data baseline.
[0053] Specifically, the basic form of the weather forecast data baseline is a two-dimensional array, expressed as Where i is the category of weather elements, including wind speed, wind direction, atmospheric pressure, temperature, rainfall, solar radiation, lightning, etc., x, y, z are latitude and longitude and altitude respectively, and t is time. When t is equal to the current time, the weather information is real-time information, and when t is greater than the current time, the weather information is forecast information. When t is less than the current time, the weather information is historical information. Real-time weather information and historical weather information can be stored forecast information, or they can be processed by various algorithms based on actual monitoring. In general, real-time weather information and historical weather information processed based on actual monitoring data can be understood as the information closest to the actual weather conditions known at the technical level. In particular, in the weather forecast data baseline, there are some arrays that are composed of weather information actually monitored. These weather information can be considered as real weather information under the condition of ignoring equipment monitoring errors.
[0054] Step 102: Determine the impact domain, which includes a spatial range and a temporal range.
[0055] Specifically, the impact domain adopts express, are respectively the longitude, latitude, altitude and time in the affected area. is a continuous interval or a discontinuous interval. Their general expressions are as follows:
[0056] The purpose of determining the impact domain is to filter the data that needs to be used from the weather forecast data baseline in preparation for the next step.
[0057] Step 103: Determine the objective function form and the weather element input type of the impact domain, where the objective function is And T>0.
[0058] Specifically, in the objective function, i is the type of weather factor that affects the objective function, c is the matrix of all control variables of the objective function except weather factors, and k represents the control variable. For example, if there are n control variables, then k = 1, 2, 3...n. The specific form of the objective function T can be obtained by using historical weather data and historical data of control variables, using tools such as regression analysis, correlation analysis, and artificial intelligence algorithms, and can be optimized through continuous iteration. It should be noted that the objective function is the core of the data processing method of weather management engineering. It may be the power generation of a wind turbine, the water level of a reservoir, or the safety threshold of a drone flight environment, as well as the management objectives of various activities related to weather changes, such as transportation cost function, logistics cost function, warehousing cost function, passenger flow of tourist attractions, and takeaway order volume.
[0059] Step 104: Set the basic equation, which is:
[0060]
[0061]
[0062] Specifically, in the basic equation, ψ is the function to be minimized, st is the meaning of constraint condition, which is the abbreviation of the English word (subject to), M is the constraint condition for real-time weather monitoring, and δ is the required accuracy constraint condition. is the forecast data in the impact domain from the numerical weather model, The analytical data for weather management that needs to be solved is called analytical solution. is the actual observation data of weather elements affecting m observation stations in the domain, is a spatial operator function, which is used to convert The element closest to the observation site is converted into the element at the same position as the observation site. δ is the accuracy of the objective function, where T is the measured value of the objective function. is the predicted value calculated using the analytical solution, ε is the required accuracy, is the inverse matrix of the background error covariance matrix used by the numerical weather model from which the weather forecast data baseline is derived. All are in vector form.
[0063] More specifically, the solution of the basic equations of weather management engineering needs to meet two conditions: first, to obtain the real-time weather monitoring data within the influence domain, that is, Here is the current time or historical time, that is 0:00 represents the current time; second, obtain the weather forecast data for the corresponding time in the affected domain and The constraints The meaning of is that the total amount of the analytical solution is conserved, that is, the obtained analytical solution must satisfy the condition that the total amount is equal to the total amount of the observed value. At the same time, the analytical solution also needs to meet the required accuracy requirements, that is, Under the above two constraints, the analytical solution is obtained based on the minimum distance deviation from the original weather forecast data.
[0064] Step 105: Exploitation The analytical solution is obtained
[0065] Specifically, correlation analysis, regression analysis, artificial intelligence algorithms, etc. are used to establish and The transformation relationship is expressed as function Then according to the function right Perform transformations in sequence to obtain analytical solutions at different times Then, the analytical solution is substituted into the objective function T in turn to obtain the predicted values of the objective function T at different subsequent times, which are recorded as
[0066] Step 106: Conduct performance evaluation and economic evaluation.
[0067] Specifically, historical data is used to evaluate the performance and economics of the data processing methods of weather management engineering, determine their economic effectiveness and continuously iterate and upgrade. Through historical data, the timeliness of the accuracy of the forecast results of the objective function calculated by the analysis solution can be evaluated using the method in Table 1. For example, using the grid data of historical rainfall forecasts, the reservoir water level is analyzed to determine the accuracy of the forecast results of the weather management engineering objective function required for reservoir water level management, and how long it is valid. The meaning is that the weather forecast data is directly Substitute the objective function T to get the predicted value, It is the forecast value obtained by using the analytical solution of the weather management engineering equation. and They represent the direct prediction accuracy of the objective function and the prediction accuracy after analysis respectively.
[0068]
[0069] Table 1 Timeliness of the forecast results using the analytical solution as the objective function
[0070] The basis for judging the effectiveness evaluation is that or When it occurs, the timeliness of the data processing method of weather management engineering is determined to be 0-n times. The forecast accuracy greater than n times will no longer meet the needs or the analysis of the data processing method of weather management engineering will no longer be valid.
[0071] By using performance evaluation, we can determine how long the time-efficiency accuracy of the objective function value obtained by reanalyzing the weather forecast data using the data processing method of weather management engineering is. In practical applications, we can select management effectiveness and continuously optimize and upgrade methods based on the actual accuracy requirements of the management objectives. At the same time, similar methods can be used for economic evaluation. First, calculate the cost of using the data processing method of weather management engineering, including the cost of obtaining weather forecast data, relevant data collection, calculation program development, management system development, and labor costs. Secondly, use the forecast accuracy evaluation data in Table 1 to calculate the economic benefits. Finally, do a cost-benefit analysis to decide whether to use the data processing method of weather management engineering to implement weather management on the management object.
[0072] Therefore, the present invention can, without changing the existing weather forecasting technology level and forecasting accuracy, model the management target for the management object, set the required accuracy of the management target, and then use the thinking of system engineering and control theory to meet the required accuracy of weather management by mathematical optimization. To a certain extent, it solves the technical problem of insufficient weather forecast accuracy and improves the use value of weather forecast data. The present invention is universal and portable. For different scenarios and different management objects, only a few elements such as the objective function and the influence domain need to be adjusted to achieve scenario conversion, and then the historical data can be used for continuous optimization and iteration to carry out engineering practice, which is convenient for practical application.
