George Kiladis retired from NOAA in April 2025 and is continuing his research as a Visiting Scholar at the Physical Sciences Laboratory (PSL/NOAA) in Boulder Colorado. His work is focused on observational aspects of the tropical atmosphere and ocean, including comparisons of observations with theory and models. His main interests include equatorial waves, tropical-extratropical interaction, air-sea interaction, and the coupling between tropical convection and the large scale atmospheric circulation. This work is geared toward better understanding of the dynamics of the tropical portion of the atmosphere-ocean system, with the ultimate goal of providing statistical data that can be used to improve the full range of models used for forecasting the weather from hourly on up to decadal time scales.
