Two-dimension numerical model of advection-radiation fogs
二维平流辐射雾的数值模拟

A two dimentional, time- depending model has been developed to simulate the formation, evolution and dissipation of advection-radiation fogs in the atmospheric boundary layer. Turbulence, radiation and advection are included in the model.The result shows that turbulence and radiation are important physical factors in the process of evolution and variation of fogs. The distribution and circulation of wind field in the atmospheric boundary layer, the advection transport of water vapour also have important influence on the above process.
