摘要
建立了一个适用于复杂地形上的三维非定常雾模式，用于研究西双版纳地区雾的生消规律。模式详细考虑了湍流、长短波辐射、凝结、蒸发、重力沉降等影响因子，特别注意了植被和气溶胶辐射效应对雾的生消的影响。利用本模式对山谷风及雾的生消过程进行了实况模拟，结果表明，模式在一定程度上反映了实际情况。
A 3D fog model is designed to investigate the evolution of the Xishuangbanna fog. The model considers turbulent exchange, long- and short-wave radiation, condensation, evaporation, gravitational settling, soil, vegetation and so on, and gives parameterizations of vegetation and aerosol radiation effects. Compared with the observations, the simulations of the formation and dissipation of mountain-valley wind and fog conform to reality to some extent.
