中文摘要:

为亚洲在地区性的气候的阶段 II 期间为内部比较的工程(RMIP ) 建模,亚洲气候用六个气候模型从 1988 年 7 月被估计到 1998 年 12 月。在这份报纸,六个气候模型的能力被分析在最后世纪的最后年期间在中国模仿几个重要极端气候事件。在 Yangtze-Huaihe 山谷上的降水异例的紧张的建模的结果在 1991 和 1998 的夏天期间比观察价值弱。为在 1991 的灾难的洪水负责的积极降水异例很好在几乎所有模拟结果,而是紧张被复制,在 1998 的降水异例的范围在建模的结果是更弱的。当严重干旱影响了诺思中国,洪水影响了华南时,因为大规模背景地的异例是模仿得好的,在 1997 的极端气候事件的空间分发被大多数地区性的模型复制,尽管有穷人,在北方的高温度区域的模拟在由所有的夏天期间当模特儿。

英文摘要:

During phase II of the Regional Climate Model Inter-comparison Project (RMIP) for Asia, the Asian climate was estimated from July 1988 to December 1998 using six climate models. In this paper, the abilities of six climate models to simulate several important ex- treme climate events in China during the last years of the last century were analyzed. The modeled results for the intensity of the precipitation anomaly over the Yang- tze-Huaihe Valley during the summers of 1991 and 1998 were weaker than the observed values. The positive pre- cipitation anomaly responsible for a catastrophic flood in 1991 was well reproduced in almost all simulation results, but the intensity and range of the precipitation anomaly in 1998 were weaker in the modeled results. The spatial dis- tribution of extreme climate events in 1997, when severe drought affected North China and flood impacted South China, was reproduced by most of the regional models because the anomaly of the large-scale background field was well-simulated, despite poor simulation of high temperature areas in the north during the summer by all models.
