摘要: The Southern Hemisphere (SH) zonal-mean circulation change in response to Antarctic ozone depletion is re-visited by examining a set of the latest model simulations archived for Chemistry-Climate Model Initiative (CCMI) project. All models reasonably well reproduce late 20th century. related SH-summer changes, such as poleward intensification westerly jet and expansion Hadley cell, are also captured. experiments exhibit quantitatively same multi-model mean trend, irrespective whether ocean coupled or prescribed. Results similar those derived from Coupled Intercomparison Project phase 5 (CMIP5) high-top which stratospheric mostly prescribed with monthly- zonally-averaged values. These results suggest that ozone-hole-induced changes robust across specific chemistry-atmosphere-ocean coupling.
