Abstract

A continuous scattered severe convection weather occurred in Ningxia Hui Autonomous Region,China during 21-25 August,2011.In this paper,the technologies for monitoring and early warning of severe convection weather were analyzed,and the indicators of grading early-warning were explored by analyzing the sounding data during the convectional process.The results indicated that,under the circulation high in the west but low in the east,a convectional process with a typical forward tilting trough configuration that it was dry and cold at high altitude but warm and moist at middle and low level occurred.There was a close relationship between a hail process and a stable 0 ℃-layer altitude and a significant decrease of -20 ℃-layer altitude,and the occurring probability of hail was high when the altitude difference between 0 ℃-layer altitude and -20 ℃layer altitude was below 1 500 m.The spots selected to compare the radar echo intensity must be equidistant.The longer the duration is,the higher the precipitation will be.The more the vertical liquid water content is,the higher the precipitation rate will be.Mesocyclone can be regarded as a monitoring indicator of hail formation.The gust front is the signal of thunderstorm wind.
