| 摘 要： | 本模式是为“重庆雾客”课题而设计的,能够通报“雾害”形成的500hPa背景形势场的正压原始方程模式。它从转报、客观分析到数值预报完全自动化。可以投入业务使用。模式提供500hPa环流形势的24小时预报。预报域覆盖整个东亚地区。模式的差分方案采用准拉格朗日平流格式。时间步长取为半小时。通过1990年11月～12月60天的预报试验表明:该模式能够较准确地预报500hPa环流形势。

| Abstract: | In this paper.an one-level primative equation model which can forecast the 500hPa height field controlling the formation of the chongqing fog is investigated. In this operational model, code interpretation,objective analysis and numerical prediction work automatically . With the domain covering East Asia and using Lagrange scheme with the time step 1/2 hour,this model gives 24-hour forecasting. The experiments during 60 consecutive days (Nov. 1-Dec. 30,1990) show that this model can give accurate prediction of 500hPa height field. |
