MIROC_Hires模式模拟我国极端降水非均匀性在CO2浓度增加下的响应
SIMULATING THE RESPONSE OF NON-UNIFORMITY OF PRECIPITATION EXTREMES OVER CHINA TO RISING CO2 USING MIROC_HIRES
摘要
Abstract
Based on the daily precipitation from an air-sea coupled climate model, MIROC_Hires, the response of non-uniformity of precipitation extremes over China to doubling CO2 has been analyzed. Under the CO2 increasing scenario (SRES A1B), the main conclusions are as follows: (1) For climatology, the precipitation extremes are concentrated over the southern part of China, while they are uniformly distributed over the northern China. (2) For interannual variance, the concentration of precipitation extremes is small over the southern part of China, while it is opposite over the northern China. (3) The warming effects on horizontal and vertical scales are different over the northern and southern part of China. Furthermore, the stability of the atmosphere over the northern and southern part of China is also different. The heterogeneous warming is one of possible reasons leading to the change of non-uniformity of precipitation extremes over China.关键词
