摘要
用GFDL气候场及GCM的模拟结果分别为区域模式(MM4)提供初始条件和边界条件,模拟了青藏高原地区夏季区域气候特征。通过比较不同初始条件和边界条件时区域模式的模拟结果,分析了初始条件和边界条件对模拟结果的影响。虽然这两种方法都模拟出了青藏高原附近的主要区域气候特征,但GFDL提供初始条件和边界条件时MM4的模拟结果明显优于用GCM提供初始条件和边界条件时的模拟结果,特别是在高层。GCM输出结果与实际资料的系统误差也导致了MM4模拟结果的系统误差。
We simulate the regional climate in the Qinghai Xizang Plateau,utilizing the regional model (MM4) and one way nested technique, compare the simulated results with different nesting methods and discuss the effects of initial and boundary conditions on the simulated results. The results show that main regional climate features are reproduced by the regional climate model but the simulated results nested with GFDL data are better than that with GCM simulated values, the errors simulated by the GCM could certainly affect the simulated results of the nested model MM4.
