英文摘要 | Due to computational constraints, interactive stratospheric ozone chemistry is commonly neglected in most climate models participating in intercomparison projects. The impact of this simplification on the modeled response to external forcings remains unexplored. In this work, we examine the importance of including interactive stratospheric ozone chemistry on the Southern Hemispheric circulation response to an abrupt quadrupling of CO2. We find that including interactive ozone significantly reduces (by 20%) the response of the midlatitude jet to CO2, even though it does not alter the surface temperature response. The reduction of the tropospheric circulation response is due to CO2 induced ozone changes and their effects on the meridional temperature gradient near the tropopause. Our findings suggest that neglecting this stratospheric ozone feedback results in an overestimate of the circulation response to increased CO2. This has important implications for climate projections of the Southern Hemispheric circulation response to CO2. |
