Comparison of two Continuous Strong Precipitation Processes in Yingtan on June 2015
摘要
Abstract
The region suffered a continuous heavy rain weather process in Yingtan on June 2015 . We divided the rainfall process into two stages and compared them by diagnostic analysis in terms of im-pacts system and formation mechanisms,using the conventional meteorological data,the regional sta-tion data encryption and NCEP/NCAR 1° × 1° reanalysis data by 6 hours. The results show that:the first stage belongs to the convective precipitation and the influencing systems mainly contain upper trough,middle and low level shear lines and low-level jet. The second stage is mainly affected by the upper trough,the subtropical high peripheral and low vortex influence,and belongs to both convective and stable precipitation. And then by comparing found that the water vapor flux convergence center and strength can Strengthen the happening of the strong precipitation. The configuration of middle and low level cyclonic vorticity and upper level anticyclonic vorticity is more conducive to the strong precipitation.关键词
