Abstract:In order to monitor and warn the heavy rainstorm weather in Wuning,using MICAPS conventional weather data,ground automatic weather station meteorological data,radar puzzle echo data and other data,using the principles of meteorology,radar meteorology and other technical methods,this paper analyzes a heavy rainstorm weather process in Wuning on May 29,2022,and resumes the forecast service in this process.The results show that the heavy rainstorm in Wuning on May 29,2022 accompanied by short-term heavy rainfall at or above 30 mm/h.The precipitation is unevenly distributed in time and space,and the heavy rain is concentrated in the central area of Wuning County.The heavy rainfall mainly occurs in the period of 08:00~14:00,and the rainfall magnitude is consistent with the change of echo intensity.The heavy rain is mainly affected by high-level trough,low-level shear line and southwest jet.The strong precipitation period is mainly affected by the repeated passing of strong monomers on the short band echo,and the echo intensity is 45~55 dBZ.The storm tracking information before the occurrence of heavy rainfall has the characteristics that the dense pointing area is parallel to the strip echo,and the rainfall lasts for a long time,which is conducive to the occurrence of short-term heavy rainfall,and has a good indication for the near forecast.The monitoring early warning,forecasting services and live verification provide valuable experience for similar weather forecasting services in the future.
