Rainfall Characteristics Analysis in Landslides Area Based on Micro Rain Radar

Abstract

It’s very important to study the characteristics of precipitation structure and internal micro-physical processes for improving the monitoring and forecast of precipitation. This paper studies the time-height profile of the reflectivity factor, radar echo analysis and comparative analysis of precipitation of the two precipitation processes from 14:30 to 15:30 and 18:00 to 20:30 on 29 May 2013 in the Wangmo county, Guizhou province of China. The results indicate that there is a good correspondence between the radar echo detected by MRR and the precipitation process, and the radar echo detected by MRR can detect and reflect the precipitation process very well. The comparative analysis of precipitation shows that MRR has higher detection accuracy for weak rainfall.
