Microphysical characteristics of a precipitation affected by cold vortex based on disdrometer

Abstract

As a remote sensing instrument of rain drop size distribution, Parsivel disdrometer is widely deployed to meteorological observation stations. The microphysical characteristics of a severe precipitation affected by cold vortex are analyzed in this paper with the help of Parsivel disdrometer. After quality control of raw datasets, the precipitation process is classified as stratiform and convective precipitation. It is showed that convective precipitation has much larger values of liquid water content, rain rate and radar reflectivity factor than stratiform precipitation.
