摘　　要：本文在中国科学院大气物理研究所二室自行设计的9层谱模式中,引入ECMWF的地形重力波阻参数化方案,取截断波数为21,进行了冬、夏两个例子的试验计算,分析讨论了重力波阻参数化对纬向平均西风剖面、纬向平均温度剖面、动能变化和预报评分的作用。结果表明重力波阻参数化方案的引入是成功的。In this paper, ECMWF scheme of topographic gravity wave drag parameterization is entered into nine levels spectral model that it was designed by Institute of Atmospheric Physics, Chinese Academy Sciences. Two cases of summer and winter with resolution T21 are computed, some effects of gravity wave drag on the cross sections of zonal mean west wind and temperature, the change of kinetic energy and forecast score are analysed and discussed. The results show that the scheme of gravity wave drag parameterization entering into the spectral model is successful.
