Abstract

The invention discloses a rainfall particle type identification method and a device. The method comprises steps that a polarization parameter set and preset temperature of rainfall particles are acquired, and the polarization parameter set comprises reflectivity, difference reflectivity, a difference propagation phase shift rate and a correlation coefficient; a parameter set corresponding to each rainfall particle type is respectively acquired, and the parameter set comprises a sub parameter set corresponding to each polarization parameter and a sub parameter set corresponding to the preset temperature; probability of a rainfall particle belonging to each rainfall particle type is calculated; the type of the rainfall particle is determined through utilizing probability of the rainfall particle belonging to each rainfall particle type. The method is advantaged in that through polarization parameter analysis processing, probability of the rainfall particle belonging to a certain type is acquired, rainfall particle type identification is realized, bases are provided for making different manual operation modes for different rainfall particle types, and manual influence weather work validity is improved.

Description

technical field [0001] The present application relates to the technical field of particle identification, in particular to a type identification method and device for precipitation particles. Background technique [0002] Artificial weather modification refers to artificially affecting the physical and chemical processes of the local atmosphere through scientific and technological means under appropriate conditions in order to avoid or mitigate meteorological disasters, rationally use climate resources, and achieve rain and snow enhancement, hail prevention, rain elimination, and fog elimination. , anti-frost and other activities. It is a scientific and technological measure that uses the physical principles of clouds and precipitation, and uses the method of spreading catalysts into clouds to transform some local weather processes in a direction that is beneficial to human beings. [0003] In artificial rainfall enhancement or hail prevention, it is necessary to understand...
