Simulation of Recent Southern Hemisphere Climate Change
Nathan P. Gillett1* and David W. J. Thompson2

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 resolution that is forced solely by prescribed stratospheric ozone
depletion. The results provide evidence that anthropogenic emissions of ozonedepleting
gases have had a distinct impact on climate not only at stratospheric
levels but at Earth’s surface as well.
