Technical field
The present invention relates to Effectiveness Evaluation of Artificial Precipitation Enhancement field, particularly a kind ofly shift to axis with radar return and to determine to increase rain artificially the method for target area and contrast district.
Background technology
Artificial snowfall operation is one of important means of three-dimensional drought resisting.In rocket artificial snowfall operation, operative goals district is the region of rocket projectile catalysis, and contrast district is the region that rocket projectile does not have catalysis.Carrying out in the statistical test of rocket ground artificial precipitation enhancement effect, taking to carry out regression analysis to the target area of increasing rain artificially and contrast district more at present, determining the artificial rainfall increased.
Choosing of contrast district and target area has been the key of statistical test.Due to the moving direction by each rocket operation cloud not equal conditions limit, repeatedly after operation, seeding with rockets district can not cover pre-determined fixed target district completely, be namely difficult to selection one piece of FX as target area.Therefore the problems such as statistical test is inaccurate are caused.This invention, by the method for tracking radar echo, solves the problem of catalytic domain all standing target area.
Summary of the invention
In order to make up the deficiency determining target area and contrast district technical method in existing rocket Effectiveness Evaluation of Artificial Precipitation Enhancement, the invention provides and a kind ofly shift to axis with radar return and to determine to increase rain artificially the method for target area and contrast district.The method carries out the result of numerical simulation according to cold cloud seeding with rockets agent line source diffusion equation, shift to based on axis by radar return, in rocket projectile catalytic domain, determine the target area of seeding with rockets, shift on axis at operation windward side radar return and determine contrast district, form the defining method of a kind of rocket operation moving target district and contrast district; The statistical test carrying out operation effectiveness conveniently, is convenient in the method determination target area and contrast district; The target area that the method is determined simultaneously is all positioned at silver iodide diffusion region, realizes all standing of silver iodide diffusion region to target area; Contrast district and target area are separated by far, and in elimination rocket projectile, silver iodide are to the pollution of contrast district; The validity check accuracy of the contrast district that employing the method is selected and target area is high.
Technical scheme of the present invention is:
Shift to axis with radar return to determine to increase rain artificially the method for target area and contrast district, implementation step is:
1) determine that radar return shifts to axis;
2) that determines rocket release catalyzer sows line;
3) shift to axis according to described radar return and sow line determination target area; Described target area is quadrangle, and axisymmetrical distribution is shifted to relative to radar return in target area; Simultaneously described target area initial sideline with sow line and overlap, target area is positioned at catalyzer diffusion region and is positioned at the downstream direction that radar return shifts to axis;
4) shift to axis according to described target area and radar return and determine contrast district; Described contrast district and target area equal and opposite in direction, shape are identical, and described contrast district and target area are separated by least 40 kilometers; Described contrast district is positioned at the updrift side that radar return shifts to axis, and shifts to axisymmetrical distribution relative to radar return.
Preferably, described target area and contrast district are rectangular region.
Further, the spacing between described contrast district and target area is 40-50 kilometer.This setting both can ensure to eliminate silver iodide in rocket projectile and, to the pollution of contrast district, contrast accuracy with the not too large increase of time interval.
As preferably, the length that axis direction is shifted to along radar return in described target area and contrast district is 40-50 kilometer.Guarantee that target area is positioned at catalyzer diffusion region.
Beneficial effect of the present invention is:
The method is convenient to determine target area and contrast district, thus is convenient to the statistical test carrying out operation effectiveness; The target area that the method is determined simultaneously is all positioned at silver iodide diffusion region, realizes all standing of silver iodide diffusion region to target area; Contrast district and target area are separated by far, and in elimination rocket projectile, silver iodide are to the pollution of contrast district; The validity check accuracy of the contrast district that employing the method is selected and target area is high.
