世纪后期南半球平流层臭氧的减少使当地气温降低，导致60° S附近平流层西风增强，改变了南半球地面气候。然而，由于《蒙特利尔议定书》的实施，南极的臭氧自2001年以来一直在恢复，该议定书禁止生产和消费臭氧消耗物质。在这里，我们表明，2001年后臭氧的增加导致了显着的变化，在上海的温度和环流的趋势。这些趋势通常与平流层臭氧损失所导致的趋势相反，包括SH极地平流层下部的变暖和SH平流层极涡的减弱。观测到的2001年后平流层温度和环流趋势的幅度比臭氧消耗时期的趋势小约50-75%。这一反应与根据臭氧和活性氯的消耗时期趋势和可变性模型得出的预期大致一致。观测到的平流层趋势在恢复期和消耗期之间的差异具有统计学意义（P< 0.05），这为南极臭氧洞愈合的动态影响的出现提供了证据。
Depletion of stratospheric ozone in the Southern Hemisphere (SH) during the late twentieth century cooled local air temperature, which resulted in stronger stratospheric westerly winds near 60° S and altered SH surface climate. However, Antarctic ozone has been recovering since around 2001 thanks to the implementation of the Montreal Protocol, which banned production and consumption of ozone-depleting substances. Here we show that the post-2001 increase in ozone has resulted in significant changes to trends in SH temperature and circulation. The trends are generally of opposite sign to those that resulted from stratospheric ozone losses, including a warming of the SH polar lower stratosphere and a weakening of the SH stratospheric polar vortex. Observed post-2001 trends of temperature and circulation in the stratosphere are about 50–75% smaller in magnitude than the trends during the ozone depletion era. The response is broadly consistent with expectations based on modelled depletion-era trends and variability of both ozone and reactive chlorine. The differences in observed stratospheric trends between the recovery and depletion periods are statistically significant (P< 0.05), providing evidence for the emergence of dynamical impacts of the healing of the Antarctic ozone hole.
