鲁西南辐射雾和平流雾过程数值模拟检验

摘要

Simulating a radiation and advection fog progress in the south-west region of Shandong Province through MM5, which is a mesoscale numerical mod, the forecast effect of the elements which can affect fog highly such as humidity, wind and temperature etc. was examined. The results showed that there is an approximately accordant trend between simulation and fact of relative humidity. The simulated temperature inversion can be referred to better when we predict fog. Within 24 hr the simulation effect of the terrain affecting on wind at 10 m is also better.%用MM5中尺度数值模式模拟鲁西南一次辐射雾和平流雾过程,检验对雾有较大影响的近地层湿度、风、温度等要素预报效果.结果表明,48 h内相对湿度模拟结果与实况变化趋势基本一致,模拟逆温层对预报雾有较好参考价值,地形对10 m风场的影响24 h内模拟效果也较好.
