Description

technical field [0001] The invention relates to the field of meteorological monitoring, in particular to a cloud particle phase identification method and system. Background technique [0002] In the work of artificial weather modification, it is difficult to evaluate the specific effect of artificial intervention in the precipitation process. The important mechanism of artificial rainfall is to disturb the supercooled water particles or provide condensation nuclei to promote the condensation of supercooled water particles, and then promote cloud droplets to collide and grow to produce precipitation. . The detection of cloud areas by existing weather radars is limited by the density of radar sites, detection distance and scanning interval. Within the detection range of radar, the farther away from the radar, the lower the scanning resolution, and it is difficult to provide high-resolution refined detection Data, in areas that cannot be covered by radar, can only be estimated...
