Biography

Timothy Cronin is an Associate Professor in Atmospheric Science at the Massachusetts Institute of Technology (MIT). His research specializes in regional-scale atmospheric dynamics and surface-atmosphere interactions to understand climate sensitivity. He focuses on convection, radiation, and clouds, employing numerical modeling experiments to elucidate the stability of Earth’s climate. Cronin’s investigations include the formation of cold air changes due to a warming climate, cloud clustering in tropical regions, and hurricane formation through dry atmospheric models. His recent work discovered mechanisms by which aerosols intensify thunderstorms in tropical regions, utilizing simulations of cloud dynamics to demonstrate that high concentrations of aerosols increase humidity surrounding clouds, leading to greater thunderstorm activity. This “humidity-entrainment” mechanism has been incorporated into weather and climate models to improve predictions of thunderstorm activity in areas experiencing changing aerosol levels. Cronin joined the MIT faculty in 2016 after completing his postdoctoral work at Harvard University and holds a PhD in Climate Physics and Chemistry from MIT.
