A method for identification of cold cloud artificial rainfall enhancement operating conditions and operating effect analysis

Abstract

The invention relates to a cold cloud artificial precipitation enhancement work condition identification and work effect analysis method. The method comprises the steps that the horizontal range and the vertical layers of work clouds and the content of cloud radar echo parameter distribution are determined through samples; the work clouds are the clouds meeting the work indicators; the horizontal range of the work clouds can be determined by drawing a closed polygon; and the radar echo parameter distribution data of three different temperature layers are extracted in the determined range of the polygon, the macro effect change after the cold cloud artificial precipitation enhancement work is judged through continuous analysis of radar echo parameter distribution before and after the work, and the original work indicator system is further corrected through the result of effect analysis. The layering method determined by the method is convenient to operate and convenient for statistical test of the cold cloud artificial precipitation enhancement work effect; and analysis of the original radar echo parameter work indicators and the work cloud radar echo parameter change before and after the work is further refined, and the analysis result is more scientific.

Description

technical field [0001] The invention relates to the field of artificial rainfall enhancement effect inspection, in particular to a method for identifying cold cloud artificial rainfall enhancement operating conditions and analyzing the operating effect. Background technique [0002] With the rapid development of my country's economy and society, the shortage of regional water resources is becoming increasingly tense, coupled with the impact of extreme climate change, the scale of artificial rainfall enhancement operations for the purpose of drought relief and reservoir water storage is gradually increasing. Artificial rainfall enhancement requires a large amount of capital investment, and its operational effect and scientific nature have gradually attracted the attention of governments at all levels and relevant departments. In the past, although the results of simple surface rainfall analysis met people's expectations for the effect of artificial rainfall enhancement, they ...

Problems solved by technology

In the past, although the results of simple surface rainfall analysis met people's expectations for the effect of artificial rainfall enhancement, they lacked inherent scientific and rational explanations, and it was inevitable to be suspected of "black box" operations. This is also an urgent need in the development of artificial rainfall enhancement. A technical problem solved

[0003] In the previous implementation of artificial rainfall enhancement operations, although the formulation of operational indicators followed the basic requirements of the principle of artificial rainfall enhancement, the concept of the requirements for operational cloud radar echo parameter indicators is relatively vague, which is bound to affect the effect of artificial rainfall enhancement operations. At the same time, in the analysis of the radar echo parameters before and after the cloud operation, its scientificity and the corresponding principle of artificial rainfall enhancement also have unclear concepts
