青藏高原单点地气交换过程的模拟试验

利用GAME-Tibet 1998 IOPs的外场观测资料，采用单点陆面过程气柱模式CLSM对青藏高原的昌都(Amdo)站和改则(Gaize)站的地气交换过程进行了模拟试验，模拟结果与观测分析的对比表明：模式对两个站陆面特征的变化和陆气之间的交换给出了比较合理的模拟结果，模拟结果与观测结果较一致。这在一定程度上表明，CLSM模式具有描述夏季高原地区两种不同下垫面陆面状况基本过程的能力。

Simulation of Land-Atmosphere Exchange Processes at Amdo and Gaize Stations over Qinghai-Xizang Plateau

Using the field observational data during GAME-Tibet 1998 IOPs, the land-atmosphere exchange processes at Amdo and Gaize Sations of Qinghai-Xizang Plateau are simulated by a comprehensive land surface model(CLSM). In which Amdo and Gaize Stations have the grassland and bare typical underlying surfaces respectively. The contrasts of the land-atmosphere exchange processes observed and simulated by the single point column model suggest that the CLSM has the capability to give a reasonable simulated result on the basic physical process of the land surface and the exchange between the land and the atmosphere in both sites.
