摘要
Abstract
According to the automatic weather stations (AWS) data, conventional weather data, FY-2c infrared satellite images and NCEP reanalysis data,the continuous heavy rainstorm process happened from June 27 to 30, 2010 in southwest Guizhou Province was analyzed. The results indicated that this continuous heavy rainstorm process was caused by southwest vortex; as shown in the 500hp aerial map, there was a stable through between Lake Balkhash and Lake Baikal, some small through and cyclonic circulation kept splitting off in front of the through,gliding, transferring and supplementing the southwest vortex in Szechwan Basin along the extendcd path of ladder through at the eastern part of plateau, which maintained the southwest vortex at the western Guizhou Province, and extended it to 200 hPa, the stagnation of the southwest vortex over western Guizhou Province for 72 h resulted in the heavy rainstorm which lasted for three days in this area.关键词
