摘要: 本文利用二维数值模式研究了倾斜地形对城市热岛的影响,地形坡度的存在增强了低层风的切变,削弱了城市热岛环流的强度。Abstract: A two dimensional numerical model is developed for studing the effect of a slightly inclined terrain on the urban heat island. As sloped angle β≠0,the wind shear within the lower levels is increased, the strength of the circulation for the urban heat island is weakened.
