一次西南涡引发暴雨的地闪特征
Lightning characteristics in a heavy rainfall process caused by southwest vortex
摘要
Abstract
Based on the Doppler weather radar echo data and the observational data from the lightning location detection equipment as well as the meteorological data from regional automatic stations,the lightning characteristics in a heavy rainfall process caused by the southwest vortex on June 9,2011 in Hubei province were analyzed.The results indicate that the location of ground lightning differs in the different stages of mecoscale convective systems (MCS).The frequencies of positive and negative lightning reach the peak values synchronously,which is one of the symbols of MCS mature.The intensive region of ground lightning and the rapid moving strong echo location of MCS are coincident.The ground lightning appears in strong echo region of MCS;they have a good relationship with radar echo between 45-55 dBz;the strong precipitation occurs in the disappearing stage of MCS.关键词
