| 摘 要： | 利用新疆北部43个气象观测站资料,引用异常气候事件和极端气候事件的判别标准,定量分析了2009/2010年冬季新疆北部的异常气候特征,总结了这一阶段的降水、气温的极端事件特征.分析表明,新疆北部2009/2010年冬季降水量大,积雪厚,积雪时间长,气温变化幅度大,多种表征降水和积雪的气象要素突破历史极值;极端事件发生频次高、范围广,极端冷事件与暖事件并存.在全球气候变暖的大尺度背景下出现降雪如此大、积雪如此厚,灾害如此重的极端气候事件,在新疆实属罕见,这也凸显了极端气候事件的多元性和复杂性.

| Abstract: | Anomalous characters of 2009/2010 winter(from 1st November to next 31st March) climate in northern Xinjiang were quantitatively analyzed based on the observations of 43 meteorological stations in 1961-2010 in terms of extreme precipitation and temperature events defined by WMO.The results show that in the 2009/2010 winter,precipitation in northern Xinjiang was heavy,snow cover was thick with a long duration,changes in temperature were very large,and several meteorological variables describing precipitation ... |
