Hiroki Tokinaga, Associate Professor

Research

I am an Associate Professor at the Hakubi Center / Disaster Prevention Research Institute of Kyoto University. My research interests include diagnostic and modeling studies of observed climate variability and change over the tropics and extratropics, with a particular focus on ocean-atmosphere interaction. I have also reconstructed historical climate datasets from in situ observations including ship and buoy measurements to identify consistent patterns of regional climate variability and change.
