Genetic Analysis of a Strong Convective Weather Process in Guannan County

摘要

To provide references for the forecast of strong convective weather process by county-level stations,through synoptic analysis,diagnostic analysis of physical quantities,analysis of satellite cloud pictures and new generation of weather radar data,the main reasons for the formation of strong convective weather process in Guannan County on May 16,2012 was analysed based on the weather situation and physical quantities.The results show that this strong convective weather process occurred under conditions of inversion layer,upper dry and low-level wet climate,highlevel convergence and low-level divergence,and unstable stratification,and surface cold front was the major factor triggering this strong convection.Besides,radar echo played an important role in the short-term impending forecast during the development of the weather.The occurrence of a strong convective weather is related to cold air activity,so we should strengthen the monitoring of cold air activity,so as to improve our warning level and service capability to forecast strong convective weather.
