【摘要】 本文简要总结了作者研究我国云雨对10GHz以上的微波衰减特征的理论结果。主要介绍利用地面微波辐射计测量云雨衰减的方法以及过去几年中所取得的观测结果,它们是各类云型的36GHz云柱单程衰减及其与云柱液态含水量的关系,35和9.375GHz降雨单程衰减值与雨强的统计资料。所有这些实测数据均同理论值作了比较。更多还原

【Abstract】 The paper describes the calculation results of attenuation characteristics at frequencies above 10 GHz due to rain and clouds in China, briefly. A measurement method using microwave radiometer is shown, and data obtained for the past few years are presented. The data include single path attenuation values of several cloud types at 35 GHz and its relation with total liquid water content and relation between precipitation attenuation at 35 and 9.375 GHz and rainfall. Finally, we compare these results with theoritical values.更多还原
