Embodiment 1

[0049] This embodiment provides a method for designing an aircraft route for artificial rainfall enhancement based on ground demand analysis, and the implementation steps are:

[0050] (1) Before the aircraft implements the artificial rainfall enhancement operation, use the MM5 model or GRAPES model to perform linear programming on the supercooled water enrichment area in the weather system to obtain the rainfall enhancement target area;

[0051] (2) In the absence of local governments’ demand approval reports on local rainfall in this year, all characteristic geographical points show water demand, and a polygon can be formed by connecting multiple locations to be increased rainfall, and the boundary of the polygon is used as the location of rainfall enhancement demand The boundary area of ​​, using the polygonal Fermat point theorem to obtain the optimal rainfall enhancement demand location on the ground;

[0052] Let the coordinates of each vertex of the polygon be (x 1 ,y ...

Embodiment 2

[0060] This embodiment provides a method for designing an aircraft route for artificial rainfall enhancement based on ground demand analysis, and the implementation steps are:

[0061] (1) Before the aircraft implements the artificial rainfall enhancement operation, use the MM5 model or GRAPES model to perform linear programming on the supercooled water enrichment area in the weather system to obtain the rainfall enhancement target area;

[0062] (2) In the absence of local governments' approval reports on local rainfall demand for this year, comprehensively consider soil moisture and water resource demand in the target area of ​​rainfall enhancement, and use descriptive geometry projection method to transform geographical points including dry and wet conditions It is a three-dimensional figure, and the projection is converted into a two-dimensional point distribution, and then the optimal rainfall enhancement demand position on the ground is solved by using the method adopted ...

Embodiment 3

[0065] This embodiment provides a method for designing an aircraft route for artificial rainfall enhancement based on ground demand analysis, and the implementation steps are:

[0066] (1) Before the aircraft implements the artificial rainfall enhancement operation, use the MM5 model or GRAPES model to perform linear programming on the supercooled water enrichment area in the weather system to obtain the rainfall enhancement target area;

[0067] (2) According to the report of local governments on demand for local rainfall this year, combined with soil moisture and demand for water resources in the target area of ​​rainfall enhancement, the descriptive geometric projection method is used to project the geographical points distributed on the plane onto a straight line, and carry The weight information of the final rainfall increase in various places is used to calculate the optimal rainfall increase demand position on the ground through the weight calculation method, and the geo...

Abstract

The invention discloses an artificial precipitation enhancement aircraft route design method based on ground demand analysis, and belongs to the field of weather influenced by manpower. Based on a traditional human image command mode; factors such as weather conditions, soil dryness and humidity and the like are integrated; parameters such as the position, the area, the soil dryness and humidity degree and the crop moisture demand distribution of an area with a rain increasing demand are analyzed and processed; and through an optimization algorithm, an optimal rainfall enhancement demand position on the ground is obtained, an aerial sowing area corresponding to the optimal rainfall enhancement demand position on the ground is calculated, and finally effective guidance on the aircraft routedesign weather modification command work is achieved.

Description

technical field [0001] The invention relates to the field of artificial weather modification, in particular to a route design method for artificial rain enhancement aircraft based on ground demand analysis. Background technique [0002] A series of problems exist in arid and semi-arid areas, such as the shortage of water resources and uneven distribution. As far as agricultural production is concerned, from the perspective of the impact of drought, if the drought continues to develop, spring sowing will be affected, and agricultural production throughout the year will be greatly affected. Large impact, artificial rainfall can alleviate crop drought, traditional artificial weather modification activities generally focus on the efficient development of water resources in the atmosphere, so that the water resources in the atmosphere can be fully converted into surface water resources as much as possible. However, the traditional rainfall enhancement model only takes the appropr...
