Abstract

A major objective in the remote sensing of convective storms by radar is the clear and reliable differentiation between regions of hail and regions of rainfall. This report describes the application of the differential reflectivity (Z(DR)) radar technique to the problem of hail detection. The procedure is based on the markedly different polarization-dependent backscatter characteristics of rain and hail. Field experiments conducted in Colorado during the spring of 1983 provide significant evidence of hail detection with this new radar technique.

摘要

雷达对对流风暴的遥感的主要目标是清晰可靠地区分雹区和雨区。本报告介绍了差分反射率(Z(DR))雷达技术在雹检测问题中的应用。该方法基于雨和雹明显不同的偏振相关后向散射特性。1983 年春季在科罗拉多州进行的现场实验为利用这种新的雷达技术进行雹检测提供了重要证据。
