| 摘 要： | 本文利用美国犹他大学气象系的辐射和云参数化模式，对ＨＥＩＦＥ期间张掖地区１９９１年春、夏、秋、冬四季资料进行了计算，讨论了晴天条件下的大气状况态地表反射率与地表比辐射率等因子对地气系统的太阳辐射收支以及短波加热率与长波冷却率分布的影响；揭示了不同季节的整层大气反射、透过与吸收特征，分析了大气中各主要吸收成分对加热率与冷却率的贡献，同时就辐射模式的垂直分辨率对加热率与冷却率的影响亦作了讨论。

| Abstract: | A parameterized radiation and cloud model developed by the University of Utah U S A has been used to compute the atmospheric radiative properties in Zhangye area in January,April,August and October,1991 during HEIFE period For cloudless atmosphere,the effects of atmospheric condition,surface albedo and emissivity on the solar radiation budget,solar heating and IR cooling rates of the earth-atmosphere system are discussed;the properties of atmospheric reflection,transmission and absorption in different seasons are revealed, respectively;in order to recognize the influence of atmosphere on radiation,the contribution of main absorbers to solar heating and IR cooling rates is analysed At the same time,the influence of the vertical layers in the model on the solar heating and IR cooling rates is also discussed simply |
