摘　　要：本文讨论了海岸地区的大气过程和空气污染模式,推导了一个海陆风环流情况下的大气污染物输送扩散模式。实例应用表明,该模式对海陆风上下层风向存在切变时的空气质量模拟是有效的。The atmospheric process in this article and air quality simulating in coast are discussed. Considering the vertical wind shear, a transport and diffusion model for sea and land breeze is derived. It is assumed that dispersion of pollutants in the upper layer and in the lower layer proceed independently in view of the different wind direction of each layer. The results of case study show that the model is available for air quality predicting in shore line.Key Words Sea and land breeze; Vertical shear of wind: Atmospheric transport and diffusion model.

关 键 词：海陆风环流 空气污染 扩散模式
