摘要:

利用国家气象信息中心气温数据集1961~2011年中国东北地区资料及NCEP /NCAR再分析资料,对东亚冬季风与东北冬季气温变化特征的对比分析表明:从20世纪90年代起,东北冬季异常冷、暖事件明显增多,冬季风异常强、弱事件也相对增多;1986年前后东北冬季气温发生增暖性气候突变,冬季风同时进入转弱阶段;冬季风在2004年进入偏强阶段,东北冬季气温在2009~2011年出现转入低温阶段迹象。冬季风通过影响200 hPa 东亚急流,500 hPa东亚大槽、乌拉尔高压,850 hPa风场,地面西伯利亚高压等的异常导致东北冬季气温的年际和年代际异常。

Abstract:

The contrastive analysis of the winter monsoon intensity index and the winter air temperature in Northeast China during 1961-2011 is made by using the temperature dataset from National Meteorological Information Center of CMA and the data of the NCEP/NCAR reanalysis. The result shows that abnormal cold and warm events increased obviously in Northeast China since the 1990’s, and the strong and weak EAWM abnormal events were relatively increased. A warming climate jump of the winter air temperature occurred in Northeast China in 1986. EAWM has turned to continuous weaker at the same time. EAWM entered the stronger stage in 2004. The winter air temperature in Northeast China appeared the emergence of signs in 2009-2011 years which was into the low temperature stage. EAWM influenced the abnormal of some systems such as the East Asian westerly jet stream at 200 hPa, East Asia trough and the high in Ural at 500 hPa, wind at 850 hPa, Siberian high on the ground to lead to the interannual and interdecadal abnormal of the winter air temperature in Northeast China.

Key words: East Asian winter monsoon, Northeast China, winter air temperature, interannual climate variation, interdecadal climate variation
