一次区域性冰雹过程的卫星雷达资料分析
Analysis of Satellite and Radar Data of Regional Hail
摘要
Abstract
In recent years,the application of satellite data was substantial increase. This paper analyzed a regional hail which took place in Dezhou on the July 14th by using FY-2 infrared imagery,meteorological observation data and doppler radar data,the study contents included radar reflectivity,threshold,physical quantity,satellite image,the weather situation and so on. The results showed that at the large circulation background of two troughs and a ridge in the Eurasian continent,cold air that comes from the back of northeast trough continued to split and bloom into trough,low level southwest warm air and upper level northwest cold air bring about stratification of convective instability which provided favorable conditions form strong convection and hail. Occurred wind shear of trough northward and development triggered strong convective weather on 850hPa at afternoon. By analyzing infrared satellite imagery and radar data found that the monitoring of cloud top temperature,basic radar reflectivity,radial velocity data,and VIL to forecast and warn strong winds,hail,heavy rain and other severe convective weather have an important role.关键词
