摘要
针对辐射传输模式在青藏高原地区的应用问题，使用Ｌｉｏｕ－Ｏｕ一维辐射传输模式及１９８２年８月～１９８３年７月青藏高原热源观测实验期间青藏高原地面、高空与卫星观测资料，在高原辐射传输模式中区分了下垫面温度与地表空气温度的作用，并利用卫星观测资料对模式改进后的实际效果进行了验证；分析了地表温度的日变化和季节变化幅度，得到了下垫面温度的简单参数化方法。
In order to achieve the goal of using the atmospheric radiative transfer model over the Qinghai-Xizang Plateau region,taking values of surface temperature in the model and effects of that on the calculation results of atmospheric longwave radiation cooling are analysed with the Liou-Ou one dimension radiative transfer model based on the data set of surface,radiosonde and satellite observation over the Qinghai-Xizang Plateau during period from August 1982 to July 1983. The effects of both underlying surface temperature( T g) and near-surface air temperature( T a) are distinguished in the radiative transfer model and the effectiveness is verified by using satellite observation data. The diurnal cycle and seasonal cycle of T g and T a are analysed and a simple method to calculate the T g from the T a is presented.
