中文摘要	利用WRF(Weather research and forecasting)中尺度气象模式结合MODIS资料反演的植被覆盖度,并同化东北半干旱区近地面气象要素,对夏季东北半干旱区的辐射和能量传输过程进行模拟,并用2009年通榆站6~8月份的通量观测资料进行验证。结果表明:通榆站模拟的向上/向下短波、向上/向下长波辐射与观测值吻合较好,相关系数分别为:0.86、0.85、0.73和0.88,偏差Bia s均在36.7 W/m~2以下,潜热、感热和地表热通量密度观测日积分值分别占净辐射的28.8%、53.4%和3.4%。WRF模式也能较好地模拟出东北半干旱区夏季地表辐射与能量分量的区域分布特征。
英文摘要	The default fractional vegetation coverage data are replaced by MODIS data and the near surface meteorology elements are assimilated by WRF model and the radiation and surface energy budget process over the Northeastern China are simulated and analyzed. The model results are verified by flux data from June to August in Tongyu station. The results showed that the simulated downward/upward shortwave and longwave radiation have good agreement with observations in Tongyu and the correlation coefficient are 0.86,0.85,0.73 and 0.88,respectively. The Bias are all less than 36.7 W/m~2, and the respective proportion of latent heat flux,sensible heat flux and ground heat flux in the net radiation are 28.8%, 53.4% and 3.4%, respectively. The regional distribution characteristics of radiation and energy components can be simulated well by WRF model.
