摘　　要：统计分析了１月份、７月份热带东太平洋海温同北半球大气Ｏ３层之间的季节性相互联系以及海温导致的Ｏ３层遥相关的空间结构。结果发现：１月份海温与Ｏ３层的空间相关区域明显地不同于７月份，并且相关符号呈相反趋势，因而由不同季节海温导致的Ｏ３层的遥相关型也不相同。此外，海温对Ｏ３层的变化存在着持续的影响，导致不同季节海温对Ｏ３层的影响效果产生叠加，使Ｏ３层对海温的响应表现出十分明显的波列结构特征。表明了热带东太平洋海温对北半球Ｏ３层的分布及其季节演变都具有重要的作用。Seasonal interaction between SST in tropical eastern Pacific and ozone layer in northern hemisphere and teleconnection spacial structure in it caused by SST effects, for January and July, are statistically analysed. The result indicates that the areas being spacially correlated between SST and ozone layer in January is greatly different from the ones in July and they show opposite tendency in relavant signs, indicating difference in teleconnection pattern for the ozone layer due to effects of SST in different seasons. In addition, persistent influence of SST on the ozone layer results in superpoition for all seasons and causes well-defined wave chains in the layer responding to SST. It is concluded that SST in the tropical eastern Pacific is of great importance to the northern ozone layer distribution and its seasonal evolution.
