中文摘要	利用WRF中尺度气象模式结合卫星反演的下垫面土地利用/植被类型资料对夏季金塔绿洲辐射和能量传输过程进行模拟, 并用2008年"绿洲系统非均匀下垫面能量水分交换和边界层过程观测与理论研究"加强期外场试验所取得观测资料进行验证. 结果表明: 晴天状况下WRF模式能较好地模拟出辐射各分量和热流密度的变化, 阴天和雨天次之; 向下长波辐射以外的各辐射分量观测值与模拟值的相关性很好, 相关系数都在O.9以上, 均方根偏差在86.6W·m~(-2)以下, 平均绝对误差都在24％以下; 绿洲能量传输主要为潜热输送, 戈壁为感热输送; 绿洲潜热、感热和地表热流密度分别占净全辐射的87.1％、9.1％和11.1％, 研究结果可为合理配置绿洲太阳辐射资源提供参考
英文摘要	The radiation budget and surface energy over the Jinta oasis were simulated by WRF mesoscale meteorological model which combined with satellite-derived underlying surface land use-types and vegetation types. The model results were verified by experiment of "Theoretical study and observations of water-energy exchange and planetary boundary on inhomogeneous underlying surface in oasis system". The results showed that the simulated radiations and heat fluxes from the WRF model generally agree well with the observations in sunny but poor in cloud and raining day; there are good correlation between radiations and surface energy components except down-ward long wave, the correlation coefficients above 0.9, RMSE are less than 86.6W·m~(-2), MAPE are less than 24%; latent heat fluxes are the main ways of energy transmission over oasis, and the sensible heat flux over Gobi; the respective proportion of latent heat flux, sensible heat flux and ground heat flux in the net radiation is 87.1%, 9.1% and 11.1%, respectively. This work is a very valuable refer to utilize solar radiation resources over the oasis areas
