Abstract In order to do a good job in the monitoring,warning and forecasting of heavy rain in Yushan during flood season,this paper uses MICAPS weather data,automatic weather station data and Jiangxi WenGIS radar jigsaw data,and adopts the principles and methods of weather and radar meteorology to analyze the process of heavy rain in Yushan County on June 20,2022.It is concluded that the circulation configuration of high-level South Asia high peripheral divergence,low-level shear line and convergence line is conducive to the occurrence of heavy rain in Yushan.The echo near Yushan has typical characteristics of short time strong precipitation echo.The echo short band trend of Yushan heavy rainstorm tends to be consistent with the moving direction of the system.The research results are expected to provide a judgment basis for the forecast of heavy rainstorm weather in Yushan.

Key words： Yushan severe rainstorm train effect echo short band
