摘要:
利用实况观测资料和雷达、自动站加密观测资料,对江淮气旋影响下广西两次(2010年6月9日和20日)降雨过程的环流形势和物理量进行深入对比分析,结果表明:两次降雨天气过程前地面和对流层中低层在江淮到江南地区均有气旋生成,广西受气旋西部切变线的影响;暴雨发生时江淮和广西各有正涡度中心配合,但强度有差异,其主要原因是200hPa南亚高压、500hPa高空槽和副热带高压北界差异所导致。广西区域是否有较强降雨过程,取决于在广西区域是否有正涡度中心活动,并与江淮气旋形成"双涡效应",使该区域的水汽得以持续汇集。
Abstract:
Based on the observation data, radar and automatic station encryption observation data, the circulation situation and physical quantity of two raining weather processes in Guangxi (June 9th and 20th, 2010) under the influence of Jianghuai cyclone were compared and analyzed. The results show that the cyclone was generated on the ground and in the lower troposphere of the area between Jianghuai area and Jiangnan area before the two raining weather processes and Guangxi was influenced by western cyclonic shear line; during the occurring of torrential rain, both of Jianghuai area and Guangxi appeared the positive vorticity center cooperation, but the intensity of these two cooperation are different, which was caused by differences of the south Asia high of 200 hpa, upper trough of 500 hpa and the northern limit of subtropical high pressure. The positive vorticity center activities appeared in Guangxi decides the intensity of rain in Guangxi, while the "double effect" formed by the Jianghuai cyclone makes the water vapor in this region continue to collecting.
