江苏一次锢囚状 MCS 和相关中涡旋MCV 的观测分析
Analysis of an Occluded-Shape Mesoscale Convective System (MCS) and Concomitant Mesoscale Convective Vortex (MCV)in Jiangsu
摘要
Abstract
Using conventional surface and upper air observation data,meteorological satellite cloud images and radar data,we analyzed the occluded characteristics and vertical structure of a mesoscale convective system (MCS)that happened in Jiangsu Province on 14 June 2009.By analyzing the mesoscale circulation on the ground surface we found that the southeast flow of closed cyclonic circulation,which developed in the eastern side of thunderstorm high pressure and the northern end of inverted trough,transported the warm and moist air to the northern side of cold thunderstorm high,froming a SE -NW oriented warm tongue and then the occluded structure.Meanwhile,based on the vertical structure of sounding data in Yangtze River Delta,the paper showed that there was cold thunderstorm high between the surface and 850 hPa,and warm meso-αscale convective vortex from 700 hPa to 500 hPa.From the statics relationship,we learned that the reason why the mesoscale convective vortex (MCV)only existed in the height of 700 hPa to 500 hPa is closely related to the thermal structure of mesoscale convective system (MCS)which was warm in the upper level but cold in the low level.关键词
