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.
