Abstract Based on FY-4A satellite data and Doppler weather radar data,the weather process of squall line occurred in Guangxi on September 23,2021 was analyzed.This paper introduces the weather conditions,and analyzes the water vapor conditions,heat and instability of the squall line according to the weather background.Finally,the meteorological elements of squall line are analyzed,and the conclusion is drawn.The results aim to improve the forecast and early warning ability of squall line in peripheral spiral cloud systems such as tropical disturbance and tropical cyclone,and promoting the application of FY-4A satellite in short-term.
