摘要
重庆是著名的“雾都”.本文建立了一个复杂地形下详细考虑长波辐射冷却、地表热量平衡、雾水沉降、水汽凝结和蒸发、湍流交换系数等的二维非定常雾模式,以实测资料为初始场,研究了一次重庆雾的形成和发展过程.对江河、热岛、辐射、地形和山城的影响,模式分别进行了数值试验.
Chongqing is a famous ' fog metropolis' , we have set up a model for complex terrain considering in details the long -wave radiative cooling, surface heat budget, gravitational settling, saturation adjustment and turbulent exchange, coefficient etc. We used the observed data as initial field to simulate the process of the formation and development of fog in Chongqing. Finally, the numerical experiments are made separately including rivers, thermal island, long -wave radiation, terrain and mountain city.
