　　Satellite observations show significant stratospheric warming trends over Southern Hemisphere (SH) high latitudes and large portion of the Antarctic polar region in spring season since 1970s.To investigate the relationship between the observed stratospheric warming and sea surface temperature (SST) increases,we performed simulations with a coupled chemistry-climate model (WACCM3) forced by observed time-varying global and tropical (30S-30N) SSTs and global SSTs with increasing observed CO2.
