Atmosphere Ocean Science Colloquium

Ice ages and the latent dynamics of the Indian Ocean

Of the tropical oceans, the Indian ocean basin exhibits the weakest gradients in winds and SST and lowest amount of interannual variability. But was the Indian Ocean always such a “quiescent” place? In this talk, I’ll discuss how paleoclimate data from the Last Glacial Maximum — the last Ice Age — suggest a notably altered climatology and the emergence of strong coupled ocean-atmosphere dynamics in the Indian Ocean. Our findings also raise the specter that such “latent dynamics” could emerge in the near future, in response to increased greenhouse gases.
