Dr. Sheshadri's group addresses fundamental questions in atmospheric dynamics and variability. Understanding atmospheric circulation could enable seasonal prediction of events such as cold snaps and heat waves, potentially impacting many lives.
The group studies atmospheric dynamics, climate variability, and general circulation. Increased confidence in quantitative climate prediction can only come from a deep understanding of the physical processes that set climate. Important physical mechanisms and interactions in atmosphere and climate dynamics will be defined and isolated in idealized models, and subsequently tested using observational and reanalysis records and with comprehensive models. Dr. Sheshadri's group's goal is to understand both how the atmosphere and ocean work and how we can improve climate models to reduce the uncertainty in future projections. Current areas of focus include mid-latitude jet and storm track dynamics, stratospheric dynamics, and stratosphere-troposphere interactions.
