摘要
为了监测预警江西飑线天气,了解飑线过程特征,文章运用常规气象观测、数值预报、多普勒雷达、FY卫星云图等资料,对2020-05-05发生在江西中北部的飑线过程进行特征分析。文章首先介绍了天气实况、天气背景、物理量统计以及数值预报产品分析;其次对雷达回波演变和卫星云图演变进行了详细分析;最后阐述了地形对雷达回波的影响。研究分析的成果以期为监测预警飑线天气提供理论依据。
In order to monitor and early warn squall line weather in Jiangxi and understand the characteristics of squall line process,the characteristics of squall line process in the middle and north of Jiangxi on May 5,2020 are analyzed by using conventional meteorological observation,numerical forecast,Doppler radar,FY satellite cloud image and other data.Firstly,this paper introduces the actual weather,weather background,physical quantity statistics and numerical forecast product analysis.Secondly,the evolution of radar echo and satellite cloud image is analyzed in detail.Finally,the influence of terrain on radar echo is discussed.The results of research and analysis are expected to provide theoretical basis for monitoring and early warning of squall line weather.
