Interdecadal changes in the frequency of winter extreme cold events in North China during 1989–2021OA
全球变暖背景下,极端天气气候事件的变化受到关注.本文研究发现, 1989-2021年期间,华北地区极端冷日数在2003和2013年发生了年代际变化.极端冷日数先增加后减少. 2003-2012年,西伯利亚-乌拉尔高压偏强,极地西风急流偏弱,有利于冷空气南下入侵华北地区,华北极端冷日数偏多.而在1989-2002年和2013-2021年,情况相反.虽然三个时段华北极端冷日的强度没有显著差异,但与其相联系的冷空气强度变得更强, 2013-2021年冷空气中心区域往西北扩张到了贝加尔湖以西地区.
