Numerical Simulation of Local and Non-Local Effects of Vegetation Change and Urbanization in a Semi-Arid Region in China
半干旱区植被减少与城市化对大气的局地和非局地影响的数值模拟

Using a mesoscale model,the local and non-local responses of the atmosphere to changes in vegetation cover and surface types in a semi-arid region are analysed.The results show that the changes in vegetation cover have a complex effect on the surface temperature with a significant diurnal cycle.Contrast to a strong and persistent warming caused by urbanization of the area,decreases in vegetation cover only give rise to a weak and intermitted warming depending on the partition of the surface net available en...
