| 摘 要： | 为更准确地研究气象因素对空气质量的影响,需进一步提高气象模式MM5的模拟效果.设计了MM5模式的6种参数化方案,选取地表温度(T2m)和海平面压力(Pslv)作为变量,通过统计学方法进行了水平和垂直方向的三维综合时空评估,并考虑了网格尺度因素的影响.结果表明:情景PX、BA表现出良好的模拟效果,情景ETA、MRFN的效果较差;通过分析情景MRFN和MRFF发现,地表方案对模拟结果影响明显;各方案对网格尺度不具有特殊的敏感性.

| Abstract: | The performance of meteorological models MM5 should be proved for the more accurate research of effect of meteorological factors to air quality.In this study,the six schemes were designed.The outputs of 2m-temperature(T2m) and pressure of sea level(Pslv) from the meteorological simulation were selected for statistical analysis.The results revealed a better performance of BA,PX between the prediction and the observation,and the relatively poor performance of ETA and MRFN.The results of MRFN and MRFF showed t... |
