摘要

为了研究芜湖夏季暴雨特征,文章利用2021年7-9月的芜湖微波辐射计资料、风廓线雷达资料及气象观测资料对芜湖暴雨个例进行温度、湿度、液态水含量及垂直廓线特征的分析.结果表明:暴雨前近地面和500~1 000 m处有逆温;暴雨开始前,低层0 km~1 km绝对湿度达到18~25 g/m3或以上,2 km~5 km液态水密度可达到0.30 g/m3,1 km处液态水密度可达到0.15 g/m3;对流性暴雨和梅雨锋暴雨具有较明显的温度、湿度区别.研究结果为微波辐射计的深入应用提供支持.

Abstract

In order to study the characteristics of summer rainstorm in Wuhu,this paper analyzes the characteristics of temperature,humidity,liquid water content and vertical profile of rainstorm rainstorm by using Wuhu microwave radiometer data,wind profile radar data and meteorological observation data from July to September 2021.The results show that there is temperature inversion near the ground and from 500 m to 1 000 m before the rainstorm.Before the beginning of rainstorm,the absolute humidity of the lower layer at 0 km to 1 km reaches 18 g/m3 to 25 g/m3 or above,the liquid water density at 2 km to 5 km can reach 0.30 g/m3,and the liquid water density at 1 km can reach 0.15 g/m3.There are obvious differences in temperature and humidity characteristics between convective rainstorm and Meiyu fornt rainstorm.The research results provide support for the further application of microwave radiometers.
