Abstract
In this study, the land–sea breeze circulation model coupled with a random-walk model is developed by the analysis of the formation and the mechanism of the land–sea breeze. Based on the data of the land–sea circulation in Dalian, China, the model simulated the diurnal variation of pressure, flow, temperature, and turbulent kinetic energy field and also provides a basis for solving the air pollutant concentration in the land–sea breeze circulation so as to estimate the economic cost attributable to the atmospheric pollution. The air pollutant concentration in the background of land–sea circulation is also simulated by a Gaussian dispersion model, and the results revealed that the land–sea circulation model coupled with the random-walk model gives a reasonable description of air pollutant dispersion in coastal areas.
