Atmospheric ozone has undergone distinct changes in the stratosphere and troposphere during the second half of the twentieth century, with depletion in the stratosphere and an increase in the troposphere. Until now, the effect of these changes on ocean heat uptake has been unclear. Here we show that both stratospheric and tropospheric ozone changes have contributed to Southern Ocean interior warming with the latter being more important. The ozone changes between 1955 and 2000 induced about 30…

The ozone–climate penalty over South America and Africa by 2100
Climate change has the potential to increase surface ozone (O 3 ) concentrations, known as the ‘ozone–climate penalty’, through changes to atmospheric chemistry, transport and dry deposition. In the

As the ozone hole begins to heal, concentrations of harmful ground-level ozone are also increasing. Work now shows the impacts that both changes are having on the Southern Ocean and our wider climate

Stratospheric Ozone Depletion: The Main Driver of Twentieth-Century Atmospheric Circulation Changes in the Southern Hemisphere
The importance of stratospheric ozone depletion on the atmospheric circulation of the troposphere is studied with an atmospheric general circulation model, the Community Atmospheric Model, version 3
The effects of historical ozone changes on Southern Ocean heat uptake and storage
Atmospheric ozone concentrations have dramatically changed in the last five decades of past century. Herein we explore the effects of historical ozone changes that include stratospheric ozone
On the Climate Impacts of Upper Tropospheric and Lower Stratospheric Ozone
The global warming simulations of the general circulation models (GCMs) are generally performed with different ozone prescriptions. We find that the differences in ozone distribution, especially in
Separating the Dynamical Effects of Climate Change and Ozone Depletion. Part II: Southern Hemisphere Troposphere
Abstract The separate effects of ozone depleting substances (ODSs) and greenhouse gases (GHGs) on forcing circulation changes in the Southern Hemisphere extratropical troposphere are investigated
Recent Southern Ocean warming and freshening driven by greenhouse gas emissions and ozone depletion
The Southern Ocean has, on average, warmed and freshened over the past several decades. As a primary global sink for anthropogenic heat and carbon, to understand changes in the Southern Ocean is
Historical Tropospheric and Stratospheric Ozone Radiative Forcing Using the CMIP6 Database
We calculate ozone radiative forcing (RF) and stratospheric temperature adjustments for the period 1850–2014 using the newly available Coupled Model Intercomparison Project phase 6 (CMIP6) ozone data
Antarctic climate response to stratospheric ozone depletion in a fine resolution ocean climate model
We investigate the impact of stratospheric ozone depletion on Antarctic climate, paying particular attention to the question of whether eddy parameterizations in the ocean fundamentally alter the
Combined Effects of Global Warming and Ozone Depletion/Recovery on Southern Hemisphere Atmospheric Circulation and Regional Precipitation
Ozone depletion led to a positive trend in the summertime Southern Annular Mode (SAM) during the last decades of the 20th century. During the present century, global warming (GW) is expected to
Drivers of past and future Southern Ocean change: Stratospheric ozone versus greenhouse gas impacts
We study the separate impacts of changing atmospheric greenhouse gas (GHG) and stratospheric ozone concentrations on past (1960–2010) and future (2010–2100) Southern Ocean conditions. To this end we
The Impact of Stratospheric Ozone Recovery on the Southern Hemisphere Westerly Jet
TLDR
Owing to the expected disappearance of the ozone hole in the first half of the 21st century, the CCMVal models predict that the tropospheric westerlies in Southern Hemisphere summer will be decelerated, on the poleward side, in contrast with the prediction of most IPCC/AR4 models.
