Preliminary Study on the Character of Raindrop Spectrum and Precipitation Mechanism in Menyuan of Qinghai

Using the raindrop spectrum information at two observation stations in the Menyuan region,the changes of the average micro-structure parameters of precipitation raindrop spectrum with precipitation process and the three common types of precipitation raindrop spectrum microstructure parameters change features with time and the type of raindrop spectrum with precipitation are anlyzed.Under the micro-structure parameters and spectral type raindrop changes,combining satellite data and other data on three types of precipitation to preliminary study the precipitation mechanism for the formation.
