2010年6月17—21日浙江西南部地区出现了连续大到暴雨:过程,造成明显的灾情。对此次过程进行研究分析,发现此次过程有以下特征:副高稳定维持,处副高边缘,有低涡东移南下;低层切变线和低空急流的南北摆动,对降水落区有重要影响;大气层结处于不稳定状态和充足的水汽条件利于强降水发生。

The persistent heavy rainfall events resulting in a significant disaster which occurred in the southwest of Zhejiang Province ,June 17 to June 21,2010. Analyzed the process,the study found that this process had the tbllowing characteristics, Firstly,the subtropical high remained stable, deputy edge,the eastward shift of the low vortex down to the south. Secondly,the lower cutting edge and low-level jet north and south swing of precipitation had important effect on the drop area. Thirdly, atmospheric stratification was unstable and sufficient moisture conditions were benefit to the occurrence of heavy precipitation.
