| 摘 要： | 把近地层引入到NCAR的区域气候模式RegCM2中(简称为RCMC1)，用该模式及1991年梅雨期间的观测资料作了3组模拟试验，并同实况进行了比较。结果表明，在区域气候模式中引入近地层后，能够更合理的模拟出地表及植被同大气之间的感热和潜热通量输送，从而改善模式模拟的月降水及月平均地面温度的分布。l0层的RCMC1比18层RCM具有更优的模拟气候的能力，且一个模式天的计算量节省227s。

| Abstract: | By use of the regional climate model RCMCI, which modifies the NCAR regional climate model Regcm2 by including a surface layer, we have performed 3 simulation experiments with observational data of June 1991. The results show that the inclusion of the surface layer in the regional climate model can simulate the distributions of monthly precipitation and monthly mean surface temperature more accurately due to the more reasonable simulations of the sensible and latent fluxes between the surface, vegetation, and the atmosphere. The simulation ability of RCMCI with 10 levels is superior to that of the Regcm2 with 18 levels. |
