Abstract:

使用一个区域气候模式(RegCM3)在IPCCSRESA1B温室气体排放情景下对东亚地区进行的高分辨率数值模拟试验数据,就备受关注的相对于工业化革命前期全球变暖2℃阈值情景下中国平均气候和极端气候事件变化进行了预估研究.结果表明,届时中国年平均温度普遍上升而且幅度要高于同期全球平均值约0.6℃,增温总体上由南向北加强并在青藏高原地区有所放大,各季节变暖幅度相似但空间分布有一定差别;年平均降水相对于1986~2005年平均增加5.2%,季节降水增加4.2%~8.5%,除冬季降水在北方增加而在南方减少之外,年和其他季节平均降水主要表现为在中国西部和东南部增加而在两区域之间减少.极端暖性温度事件普遍增加,而极端冷性温度事件减少;中国区域年平均的连续5天最大降水量、降水强度、极端降水贡献率和大雨日数分别增加5.1mm,0.28mmd-1,6.6%和0.4d,而持续干期减少0.5d,其中大雨日数和持续干期变化存在较大的空间变率.
