The statistical characteristics of different types of precipitation particles are compared and analyzed from the aspects of precipitation particle raindrop spectrum distribution, precipitation inversion product and actual precipitation change trend consistency by using the surface precipitation and raindrop spectrum data of three weather processes with different precipitation properties in Weining, Guizhou from 2019 to 2020 and combined with macroscopic quantities such as precipitation, precipitation intensity,precipitation duration and microscopic quantities such as precipitation particle size, shape, and velocity.The results show that: ①The number and uniformity of precipitation particles can reflect the change characteristics of precipitation of different natures;Convective cloud precipitation has a large number of particles with a large increase and uneven distribution; stratiform cloud precipitation has a small number of particles with a small increase and evenly distributed. ②The range of particle diameter and particle velocity of different precipitation types is quite different,the particle diameter of precipitation is mainly concentrated between 0.562~0.812 mm, accounting for about 42.3% of the total ,while the particle velocity of precipitation is mainly concentrated in 3.8~5.2 m/s，about 36.7% of the total. ③The actual precipitation, spherical precipitation, and the maximum peak of the number-concentration precipitation have a good correspondence, and the different peak points , waveform increasing and decreasing trends are basically the same; the relative difference between the actual precipitation and the spherical precipitation is small,the relative difference between the precipitation and the concentration of precipitation is relatively large, which is directly related to the two algorithms. ④The equivalent mass of precipitation particles is directly proportional to the diameter and number of precipitation particles, which is consistent with the actual precipitation accumulation,the estimated precipitation value is closer to the true value, but influence of particles (smaller than 0.312 mm and larger than 6.5 mm)on precipitation accumulation should be considered.
