摘要
为了真实模拟干旱、半干旱地区以及湿润地区的陆面与大气之间的能量和物质交换 ,发展了一个具有普适性的南京气象学院 ( NIM)陆面过程 ( LSP)模式。该模式是由等温植被参数化方案和本文建立的土壤模式所组成。土壤模式又分为五层模式和两层模式两种。利用 1 979年 5~ 8月“青藏高原气象科学实验”资料作验证 ,同时将五层模式与 Deardorff( 1 978)陆面模式、两层模式作了对比 ,结果表明五层土壤模式的模拟效果较好 ,它比 Deardorff模式优越 ,也比两层土壤模式模拟效果稍好一些。
WT5BZ]A universal NIM land surface process (LSP) model is proposed to simulate the energy and mass exchanges really between the land surface and the atmosphere in the arid,semi arid and moist regions. The model is made up of the soil model which has two schemes (five layer and two layer model)in the paper and the isothermal vegetation parameterization scheme presented by Chen Wanlong and Shao Haiyan recently. It is tested by using QXPMEX data from May to August in 1979, and the comparison has been done among five layer model,two layer model in the paper and Deardorff's model(1978). The result shows that this five layer model is superior to Deardorff's model and the simulated result is also a little better than that of two layer model. [WT5HZ]
