基于地基微波辐射计对武汉夏季暴雨过程的观测分析
Analysis of a Heavy Rain Process in Summer by the Ground-Based Microwave Radiometer in Wuhan
摘要
Abstract
Based on the data measured by ground-based microwave radiometer with high spatial and temporal resolution and satellite infrared images, this paper analyzed the relationship between meteorological elements and precipitations in a heavy rain process in Wuhan during 12-13 July 2012. These results showed that: Firstly, the values of the relative humidity, the liquid water content, the unstable energy and the altitude of their maximum values in the precipitation period were all significantly greater than that in the precipitation period, which illustrated that the corresponding relationship with these variation characteristics of elements and the precipitation, and it also showed a high reliability of the analysis of precipitation process by ground-based microwave radiometer. Secondly, the precipitation was divided into the weak rain and heavy rain by an hourly rainfall of 10mm. The height of the cloud was zero only in the heavy rainfall period. The vertical distribution of temperature had an inversion during the period of precipitation, and the altitude of the inversion was higher in heavy rain period than that in the other. When the rain occurred, the bottom of the water vapor density raised with high value, and there was the large value center of> 26 g/m3 in the lower troposphere during the heavy rainfall period. The precipitation could be further divided by the ground-based microwave radiometer data, which can help to clarify the feature of the rain group and the precipitation efficiency.关键词
