| 摘 要： | 本文利用一个三维中尺度模式模拟了长江三角洲地区的海陆风环流状况，以及城市发展后动力热力效应对环流的影响，其中热力效应主要考虑了城乡反照率的差别，模式考虑了海陆温差、通量传输、太阳辐射、科里奥利效应等因子。模拟结果得到了长江三角洲地区的夜间垂直环流状况，辐散辐合带分布，预测了城市发展后的环流情形。为大气扩散评价以及城市建设规划提供了一定的依据。

| Abstract: | In this paper, a thwtimensional numerical meso-scal model was carried out to shaulate the land-sea breeze circulahon in the nighttime in the Chang her delta area, thc dyn- and therm-al effect on the circulation due to city expansion was also shaulatal. The roughness and-alboo differ-ence between city and rural was conthe. The nux transfcr, sotar ndation, Coriolis Coriolis effect.etc Were also included in this model. The simulation results showed vertical circulation condition, divegence and convergence zone. The circulahon condition after city expansion was als0 given. It provided some bases for atm0spheric diffusion and city constnation. |
