摘要:

干旱区的气候模拟有着很强特殊性。气候模式是研究和探讨干旱区形成物理机制的有效手段和工具。介绍了近年来国内外干旱气候数值模拟和试验的研究与进展,总结和评述了陆面过程中地表反照率、土壤湿度、植被状况的参数化和对气候的影响,讨论和阐述陆面过程在气候模拟中的重要性。对干旱区的气候和天气灾害的数值模式模拟研究作了一些评述,并对干旱区数值模拟的有关问题进行了讨论和展望。指出干旱区陆面过程的深入研究和十旱区陆面参数的标定,是改进干旱区气候模拟的重要途径。

Abstract:

It has very intensive particularity in climate simulation on arid area. Climate numerical models are useful means and tools for study the physical mechanism of arid area' s form. Developments on arid climate numerical simulations and experiments were introduced in this paper ,and surface albedo ,soil humidity and parameters of vegetation and their effects on climate were summarized. We also discussed the significance of land一surface process on climate simulation. And then we reviewed numerical studies on climate and weather disasters in arid area. Finally ,it was pointed out that thoroughly studies on land一surface process in arid area and demarcate for parameters of land surface is an important approach to improve numerical simulation in arid area.

Key words: drought climate , numerical models and simulations , land一surfaceprocess, weather disasters
