【摘要】 本模式为针对大气环流模式所发展的一个简单的陆面过程模式，它包含：（１）地表温度计算，（２）冠层叶面贮水量和土壤湿度计算，（３）陆面与大气之间的水分和能量交换。对于表面温度和含水量的计算，采用的是联立求解计算方案，即耦合计算。植被冠层叶面的辐射特性和冠层形态对冠层中的辐射交换的影响得到有效和尽可能简单的模拟。另外，植被的气孔阻抗、表面与大气之间的水热交换通量和土壤中的水热输导作了较为细致的描写。利用此模式开展了对两个不同覆盖类型的陆面过程的模拟，模拟和观测的表面通量、温度和湿度较为相近。更多还原

【Abstract】 A simple land surface model for AGCM is introduced. It incorporates the calculations of ground temperature, canopy interception and soil wetness with a complete coupled numerical scheme. Plant morphology and leaf radiative properties have been considered in the treatment of radiation transfer within canopy simply and effectively. The parameterization for stomatal resistance, turbulent fluxes between surface and atmosphere, and heat and water transfer within soil has been presented. The scheme has been tested in three off-line experiments with the help of observational time series.更多还原
