【摘要】 利用区域大气模拟系统RAMS(RegionalAtmosphericModellingSystem),对北京地区2002年7月8～10日的地面风场进行了模拟,并将结果与同期的实际地面风场进行了对比。对比结果表明,结合高分辨率地表植被类型资料与地形资料,RAMS模式可以很好地再现北京地区地面风场的时空变化特征。更多还原

【Abstract】 By using of Regional Atmospheric Modelling System(RAMS), the surface wind field in Beijing district is modeled. The period of numerical modelling is from July 8th - 10th, 2002. Compared with the real surface wind field in the same period, it can be found that RAMS can fairly well reproduce the spatial and temporal variation of real surface wind field in Beijing on the condition that high resolution vegetation type data and topography data are used in modelling.更多还原
