利用TRMM/PR资料分析1998年GAME/HUBEX期间梅雨锋雨带结构

摘要

结合1998年GAME/HUBEX试验期间的常规观测资料,利用TRMM/PR产品分析了一个梅雨锋面雨带的结构以及一些大气学特征.星载测雨雷达(PR)能够在一个广大的范围内提供锋面雨带的某些细节特征和内部结构.利用PR资料得出的结论与利用常规观测资料诊断分析的结果相当一致.以往根据地面雷达发展的雷达气象理论仍然适用,并且效果更加准确可靠.这说明在降水空间结构以及梅雨锋特征的分析中,PR有相当的优势和潜在的价值.%A method is investigated to analyze the structure and the synoptic characteristics of a frontal rain belt according to the combination of TRMM/PR images and conventional weather data during the 1998 GAME/HUBEX. The space-borne precipitation radar (PR) provides some detailed characteristics and inner structures of the frontal rain belt over a large area, and the synoptic analysis for this frontal case is also presented. It is demonstrated that the traditional theories of radar meteorology are still applicable, while PR has great advantages for showing the spatial distribution of rainfall and has potential value for analyzing the characteristics of the Meiyu front.
