摘要

摘要: 对1961～2010年间北半球大气环流背景异常变化及其东亚冬季风指数(东亚大槽位置指数-CW、西伯利亚高压指数-SH)与青藏高原降雪之间在年代际尺度上的相关关系进行了分析,结果表明:北半球冬季行星波年代际尺度上的异常导致了青藏高原地区冬季降雪在年代际尺度上的变化,北半球行星波“冬三(波)”流型的年代际尺度变化是青藏高原地区冬季降雪年代际尺度上增加/减少的环流背景;青藏高原冬季降雪与东亚冬季风之间也存在着年代际尺度上的显著相关。相对于1961～1986年间的冬季风减弱,青藏高原地区冬季降雪量呈现出增加趋势。结果也指出,青藏高原地区的冬季降雪、CW和SH在1986年前后存在一次显著的突变;突变后北半球冬季三波流型明显增强,青藏高原地区的降雪也相应发生了由多到少的变化。

Abstract: The relationships of the general circulation and East Asian winter monsoon (EAWM) index anomalies [e.g., the East Asian trough location index (CW), Siberian High intensity index (SH)] with the winter snowfall (WS) over the Tibetan Plateau (TP), as well as the interdecadal characteristics, during 1961-2010, are analyzed. The results show that: 1) The abnormalities of winter planetary waves in the Northern Hemisphere (NH) impact on the WS over the TP on interdecadal scales; 2) The variations of the planetary wave pattern in the NH, “Three Troughs/Ridges in winter”, are the background circulation for the WS change over the TP on interdecadal scales; 3) The WS over the TP and the EAWM indices indicate significant correlation on interdecadal scales; 4) The WS increases over the TP with a decreasing trend of the EAWM during 1961-1986; 5) The WS over the TP, the CW and SH, all show an abrupt change around 1986. After this abrupt change, the intensity of the winter “three troughs” pattern demonstrates a stronger variation, while the amount of WS over the TP declines.
