Signatures of the Antarctic ozone hole in Southern Hemisphere surface climate change
1 Roughly 90% of atmospheric ozone is found in the lower stratosphere in the ozone layer. Since about the 1970s, anthropogenic emissions of ozone-depleting gases have led to depletion of ~3–4% of the total overhead ozone averaged over the globe1. The strongest depletion is found over Antarctica during spring, when photochemical processes combine with a unique set of meteorological conditions to...
متن کاملPotential for Southern Hemisphere climate surprises
Climate model results suggest that future climate change in Antarctica will be accompanied by continued strengthening and poleward contraction of the Southern Ocean westerly wind belt. Paleoclimate records suggest past changes in the westerly winds can be abrupt and that healing of the Antarctic ozone hole could lead to poleward contraction of the westerlies and increased meridional atmospheric...
متن کاملInterpretation of recent Southern Hemisphere climate change.
Climate variability in the high-latitude Southern Hemisphere (SH) is dominated by the SH annular mode, a large-scale pattern of variability characterized by fluctuations in the strength of the circumpolar vortex. We present evidence that recent trends in the SH tropospheric circulation can be interpreted as a bias toward the high-index polarity of this pattern, with stronger westerly flow encir...

متن کاملSimulation of recent southern hemisphere climate change.
Recent observations indicate that climate change over the high latitudes of the Southern Hemisphere is dominated by a strengthening of the circumpolar westerly flow that extends from the surface to the stratosphere. Here we demonstrate that the seasonality, structure, and amplitude of the observed climate trends are simulated in a state-of-the-art atmospheric model run with high vertical resolu...
