使用垂直和角度详细的平面平行微波辐射传输模型研究了大冰颗粒对从强雷暴上方空间观测到的亮度温度 T(B) 的时间依赖性影响。在 EHF/SHF 频谱中的 10 个不同频率下，研究了大冰粒对演化模型雨云上的被动微波 T(B) 的影响。结果表明，在该模拟中引入的与频率相关的垂直分布广义发射/散射加权函数是为了垂直解析单个云和降水层对 T(B) 的贡献，可用于识别负责调节大气顶部 T(B) 大小的特定层。
The time-dependent influence of large ice particles on the brightness temperatures, T(B)s, that would be observed from space above severe thunderstorms is investigated using a vertically and angularly detailed plane-parallel microwave radiative transfer model. The impact of large ice particles on passive microwave T(B)s over an evolving model rain cloud was examined at ten separate frequencies in the EHF/SHF spectrum. It is shown that the frequency-dependent vertically distributed generalized emission/scattering weighting functions, introduced in this simulation to vertically resolve the contributions by individual cloud and precipitation layers to the T(B)s, can be used to identify the specific layers responsible for regulating the magnitude of top-of-atmoshere T(B)s.
