| 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-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-surface process in arid area and demarcate for parameters of land surface is an important approach to improve numerical simulation in arid area. |
