| 摘 要： | 利用地球辐射平衡试验（ＥＲＢＥ）和国际卫星云气候计划（ＥＳＣＣＰ）提供的总云量、得星反射率资料，计算并分析了青藏高原地气系统年、月平均云对太阳短波吸收辐射的强迫，揭示了其与总云量的关系。结果表明：高原的短事射云强迫与总云量有较好的非线性相关，呈幂指数形式，且季节变化明显；短波辐射云强迫的地理分布与高原云的分产好，高原主体和北部是短波辐射云强迫的低值区，高原东南部和西部边缘迎风部位为强迫的高值区。

| Abstract: | In terms of data provided by ERBE and ISCCP, effects of total cloudiness on earth atmosphere system absorbed shortwave cloud radiation forcing (SWCRF) are investigated over Qinghai Tibet Plateau on an annual and a monthly basis separately. It turns out that there is a good power law correlation between them,and both have obvious seasonal variations. The SWCRF's geographical distribution accords well with that of the total cloudiness over the region and its value is lower over the main and north parts, and higher over the south east part and the windward side of the west edge. |
