摘要
本文利用地球辐射平衡试验 ( ERBE)和国际卫星云气候计划( ISCCP)提供的总云量、行星反射率资料 ,计算并分析了我国年、月平均云对地气系统太阳短波吸收辐射的强迫及其敏感性系数 ,揭示了它们之间的关系 ,最后绘制了地气系统短波辐射云强迫的全国分布图。结果表明 :我国地气系统短波辐射云强迫及其敏感性系数都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总云量配合较好。
Based on the data of toal cloud amount and planetary albedoes provided by ERBE and ISCCP,the effects of the total cloud amount on earth-atmosphere system absorbed shortwave cloud radiation forcing (SWCRF) in China and relevant sensitive parameters are investigated.The nationwide distributions of SWCRF are analyzed,either.Results show that they both have good power-law correlation with total cloud amount,and have obvious seasonal variations.The geographical distributions of SWCRF accord well with those of total cloud amount in China.
