Based on the Regional Atmospheric Modeling System and by means of Grid Nesting technique, anested numerical forecasting model system, the City-scale Meteorolog y Model(C-βM)nested to the Regional- scale Meteorology Model(R-αM), has been developed, w hich can supply meteo rology data for air pollution forecast.Comparisons betw een five practical fo recast results f rom R-αM and C-βM and two corresponding outputs of hydrostatic models ———Eta model (only regional-scale forecasting model)and M-βM (only cityscale forecasting model)are made.The result s show that the forecast made by R-αM and C-βM can more accurately reflect the evolution rules of the practical synoptic system than those of Eta model and M-βM.The former two model-predicted results are both more reasonable and bet ter than those of Etamodel and M-βM apparently.The nested model system supplies a good w ork-platform for air pollution operational prediction
Key words： air pollution forecast; grid nesting; local circulation
