摘要/Abstract

摘要： 本文利用 NCEP/ NCAR 再分析资料驱动 MM5V3 区域气候模式, 对东亚地区的气候进行了20 年(1982- 2001)的长期模拟, 分析了模式对中国地区地面温度和降水的模拟能力. 分析结果表明: 模
式对中国地区地面温度和降水的空间分布形态具有较好的模拟能力, 但在中国大部分地区对地面温度的模拟偏冷, 对降水的模拟偏多; 模式对地面温度年际变化的模拟好于对降水年际变化的模拟; 模式能
较好地模拟地面温度和降水的季节变化特征, 其中地面温度在夏半年的模拟结果优于冬半年的, 降水则相反; 模式对于一些极端气候要素, 如日最高、最低地面温度, 强降水等也具有一定的模拟能力.

Abstract: This paper presents a 20 -year ( 1982- 2001) simulation of MM5V3 driven by NCEP/ NCAR Re -analysis data over East Asia. The simulation results of surface air temperature and precipitation over China are compared with
the observation. Results show that the MM5V3 model has the capability to simulate the spatial patterns of both surface air temperature and precipitation, though in most areas surface air temperature is underestimated and
precipitation is overestimated. MM5V3 gives a better performance in simulating the inter -annual variability of surface air temperature when comparing to precipitation. Monthly cycles for both surface air temperature and precipitation
are well reproduced by the model. The analysis shows that the model is also able to reproduce the extreme climate conditions, such as daily maximum/ minimum temperature and precipitation intensity.
