Physical Geography seminar: What can paleo-data tell us about Ice Age Southern Hemisphere westerly winds?

The Southern Hemisphere westerly winds are important drivers of large-scale changes in the global ocean’s heat, nutrient, and carbon cycling. However, neither climate models nor paleo data agree on the magnitude, or even the sign, of the change in wind strength and latitudinal position during the last Ice Age. This presentation combines large-scale data compilations with model simulations to address how Ice Age westerly winds may have changed.
