多普勒雷达资料的直接同化对降雨预报的影响

Impacts of the Direct Assimilation of Doppler Radar Data on the Rainfall Forecast

摘要: 利用中尺度数值模式WRFV3.1及其三维变分同化系统WRFVAR3.1,对2008年8月10日奥运期间北京地区发生的一次强对流天气过程进行了多普勒雷达资料变分同化试验,并对同化结果和降水预报进行了对比分析。结果表明:(1)雷达资料的同化能有

Abstract: Using the Model WRFV3.1 and its 3DVAR system WRFVAR3.l Doppler radar data variational assimilation experiments are performed on a heavy convective rainfall process occurred at Beijing on 10 August 2008 when the O
