摘要

[Objective]The aim was to study the heavy rainstorm by tropical storm ' Meari' in Liaoning. [Method]Based on the ground data,radar data,numerical report data,encrypted automatic station and NCEP reanalysis data,the heavy rain process by tropical storm ' Meari' was analyzed. The changes of each physical quantity were discussed while the tropical storm moving northward. [Result]The subtropical high pressure and Mainland high pressure jointed and maintained,forced ' Meari' turned northwest. The low-level southeast jet by ' Meari' provided full water transmission and layer unstable conditions. The heavy rain mainly distributed in the tongue area of high energy,and the total energy was a key index to predict the rainfall area. [Conclusion]The study provided reference for the report business.
