摘要
文章运用FY-4A卫星资料和多普勒天气雷达等资料,对2021-09-23发生在广西的飑线天气过程进行应用分析。文章介绍了天气实况,并根据天气背景对飑线产生的水汽条件、热力和不稳定性进行分析,最后对飑线过境时的气象要素做出分析,得出结论。所得结果旨在提高发生在热带扰动、热带气旋等外围螺旋云系中飑线的预报预警能力,促进FY-4A卫星在短临短期中的应用。
Based on FY-4 A 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-4 A satellite in short-term.
