中文摘要: 利用中国气象科学研究院的三维对流云模式模拟了1 998年发生在我国武汉地区的特大暴雨过程中的对流云。在模拟云的成熟阶段,模拟结果和地面最大降水量实况及热带测雨卫星TRMM(TropicalRainfallMeasureMission)的降水雷达PR(Pre cipitationRadar)的零度层高度和降水粒子达到的高度较接近。将该云物理模式的输出结果输入到Liu的三维辐射模式的输入场,模拟了以TRMM的微波成像仪TMI(TRMMMicrowaveImager)的扫描角为入射角,频率为85.5GHz和37.0GHz的星载微波辐射仪接受到的亮温,模拟的结果表明云中各微物理量的分布对上行微波辐射的影响较大。

Abstract:The convetive cloud system on 20 July 2003 in Wuhan region is simulated with a 3-D convective precipitating cloud model. The microphysical characteristics of a mature convective system derived from 3-D cloud model approach to the results from TRMM TMI and PR products. The result from the cloud model is then used as input into a 3-D microwave radiative transfer model that calculates the upwelling radiance received by the rediometer aboard the satellite. The result shows that the structure of cloud has a strong influence on the upwelling microwave radiation.
