| 摘 要： | 按WMO提供的标准，提出了划分强爆发性增温(Sudden Stratospheric Warming，简称SSW)事件的指标，用NCEP／NCAR 30 hPa层逐日温度、高度资料，确定了1950-2002年1-3月期间的35次强SSW事件。在此基础上，给出了强SSW事件发生的气候及异常特征，并从北半球中高纬臭氧及日照年际变化及其年际异常出发，给出了这些特征的部分成因。

| Abstract: | Two indices for strong SSW events are put forward in this paper,according to the WMO standards.Using the NCEP/NCAR reananysis daily temperature and height data at 30hPa level,35 strong SSW events during January to March from 1950 to 2002 are determined.The climate and its anomalous features of SSW events are given,and their formation mechanism is partly explained by the interannual change and abnormality of sunshine and ozone distribution in the mid-high latitudes in the Northern Hemisphere. |
