Abstract: 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.
