| 摘 要： | 中尺度区域气候模式RIEMS中陆面过程使用BATS模式,其缺点是土壤内部过程较为简单,本文把10层土壤模式引入BATS,代替原来的二层土壤模式,并采用了TOPMODEL水文模式中的一些处理方法,使土壤温度、水文的计算更为合理,模拟二个个例,每个例均为夏季一个月的模拟,表明在降水、气压场、流场上均较原RIEMS模式为优,因而是对原RIEMS模式一个改进。

| Abstract: | In meso-scale regional climate model RIEMS,BATS model is used as the land surface process model,its shortcoming is that its soil internal process is simpler.In this paper,the 10 layers soil model is introduced in BATS instead of original 2 layers soil model,and some concepts of TOPMODEL hydrological model are used.Then,the temperature and water in soil can be computed more reasonably.2 cases in summer are simulated,both periods are a month long.It is shown that the precipitation,sea surface pressure,stream fields on 850 hPa are all simulated better than the original RIEMS,it is an improvement to the original RIEMS model. |
