摘要

(SAH ) 一个气候模型的能力被分析灵活联合 GCM 的 110 年的产量估计高复制南亚的气候的人物,版本 0 (FGCM-0 ) 。把 FGCM-0 的结果与 NCEP/NCAR 分析数据作比较, FGCM-0 更好举办的主要调查结果表演在 100 hPa 导致重力势高度域的模拟,并且相当复制主要大气循环中心。然而,仍然与分析数据相比在模仿的结果有一些差别。联合模型成功地也复制 SAH 的吝啬的季节变异,也就是说,它从太平洋搬到亚洲大陆,从冬季在西藏的高原上留下到夏天,然后从夏天从西藏的高原撤退到太平洋到冬季。然而,这观察到在 SAH 位置和夏天降水模式之间的关系不能相当在 FGCM-0 被复制。

Comparing the results of FGCM-0 with the NCEP/NCAR reanalysis data, the major findings show that FGCM-0 has better results in simulation of the geopotential height field at 100 hPa, and reproduces fairly the main atmospheric circulation centers. However, there are still some differences in the simulated results compared with the reanalysis data. The coupled model also successfully reproduces the mean seasonal variation of the SAH,that is, it moves from the Pacific Ocean to the Asian continent, remaining over the Tibetan Plateau from winter to summer, and then withdraws from the Tibetan Plateau to the Pacific Ocean from summer to winter. However, such observed relationships between the SAH positions and the summer precipitation patterns cannot be fairly reproduced in the FGCM-0.
