| 摘 要： | 本文对海气间湍流通量计算的参数化进行了两个方案的试验。第一个是对气候模式ＣＣＭ３中的计算方案作了改进，用半解析的计算方法代替纯迭代的方法，减少了计算量而达到相同精度。第二个是用Ｂｒｕｔｓａｅｒｔ提出的廓线函数计算海面通量，达到了当前最精确模式相同的精度。这二种方案均可用于大气模式或用于由实测气象资料求通量。

| Abstract: | In this paper,two experiments on the computation of the fluxes over sea have been performed.The first is to improve the scheme in the climate model CCM3 by using a semi-analytical scheme instead of pure iteration method.This method simplifies the computation and at the same time,attains the same accuracy.The second is to compute the fluxes over sea by using the profile function suggested by Brutsaert.Its accuracy is the same as the current other most accurate model.These two schemes can be used in atmospheric models or to compute the fluxes using the observd data. |
