摘　　要：文章提出了一种简单且适用于大气环流模式（ＧＣＭ）的冰云辐射参数化．利用该参数化和ＵＧＡＭＰ大气环流模式研究了混合云在ＧＣＭ气候模拟中的重要性．结果表明，云的相态变化及其所产生的反馈作用对模拟的气候状态有显著的影响．在高纬地区，云的相态变化可使地气系统净辐射增加，而在热带则使净辐射减少．A Scheme of simple radiative parameterization of ice clouds suitable for use in GCMmodel is presented. The importance of mixed-phase clouds in GCM climate simulations is investigated using this scheme together with UGAMP general circulation model. It is foundthat the changes in cloud phase state and the effect of its feedback have a significant impacton the model climate. In the high latitude regions, the net radiation in the earth-atmospheresystem could be increased due to the changes in cloud phase state, whereas the net radiationcould be decreased in the tropics.
