一个适用于气候研究的陆面过程模式

AN IMPROVED LAND SURFACE PROCESS MODEL FOR CLIMATE RESEARCH

本文根据Dickinson等提出的陆面过程参数化方案,改进和发展了一个适用于气候研究的陆面过程模式。文中主要介绍了模式的结构和方程组,最后利用河西地区的观测资料作数值模拟,并与根据观测资料计算的感热和潜热以及观测得到的净辐射进行了对比,结果表明模式的计算是可行的。

A land surface process model has been developed and improved according to Dickinson's parameterization scheme [l,2]. The model describes macroscopically biophysical process of vagetation and hydrologic and thermal balance of soil so as to more accurately calculate the transfers between the earth s surface and atmosphere in the momentum! heat and moisture In this paper, we mainl introy-duc. the basic structure and equations of the model. Meanwihile, two numerical experiments have been completed by using the observational data in Hexi region, Gansu province and the results of the experiments show that the property of the model is reliable. The climate sensitivities of the model will be tested and discussed further in the reference [7].
