Northward shift of the southern westerlies during the Antarctic Cold Reversal
Inter-hemispheric asynchrony of climate change through the last deglaciation has been theoretically linked to latitudinal shifts in the southern westerlies via their influence over CO 2 out-gassing from the Southern Ocean. Proxy-based reconstructions disagree on the behaviour of the westerlies throu...

Inter-hemispheric asynchrony of climate change through the last deglaciation has been theoretically linked to latitudinal shifts in the southern westerlies via their influence over CO 2 out-gassing from the Southern Ocean.
