Tropospheric temperature response to stratospheric ozone recovery in the 21st century
Recent simulations predicted that the stratospheric ozone layer will likely return to pre-1980 levels in the middle of the 21st century, as a result of the decline of ozone depleting substances under the Montreal Protocol. Since the ozone layer is an important component in determining stratospheric and tropospheric-surface energy balance, the recovery of stratospheric ozone may have significant...
متن کاملComment on “ Tropospheric temperature response to stratospheric ozone recovery in the 21 st century ” by Hu et al . ( 2011 )
Stratospheric ozone recovery is expected to figure prominently in twenty-first century climate change. In a recent paper, Hu et al. (2011) argue that one impact of ozone recovery will be to enhance the warming of the surface-troposphere system produced by increases in wellmixed greenhouse gases. Furthermore, this enhanced warming would be strongest in the Northern Hemisphere, which is surprisin...
متن کاملThe Impact of Stratospheric Ozone Recovery on Tropopause Height Trends
The evolution of the tropopause in the past, present, and future climate is examined by analyzing a set of long-term integrations with stratosphere-resolving chemistry climate models (CCMs). These CCMs have high vertical resolution near the tropopause, a model top located in the mesosphere or above, and, most important, fully interactive stratospheric chemistry. Using such CCM integrations, it ...
متن کاملMitigation of 21st century Antarctic sea ice loss by stratospheric ozone recovery
[1] We investigate the effect of stratospheric ozone recovery onAntarctic sea ice in the next half-century, by comparing two ensembles of integrations of the Whole Atmosphere Community Climate Model, from 2001 to 2065. One ensemble is performed by specifying all forcings as per the Representative Concentration Pathway 4.5; the second ensemble is identical in all respects, except for the surface...
متن کاملThe contribution of ozone to future stratospheric temperature trends
The projected recovery of ozone from the effects of ozone depleting substances this century will modulate the stratospheric cooling due to CO2, thereby affecting the detection and attribution of stratospheric temperature trends. Here the impact of future ozone changes on stratospheric temperatures is quantified for three representative concentration pathways (RCPs) using simulations from the Fi...
