My research aims to elucidate fundamental questions about climate such as, What controls the surface temperatures and winds? What shapes rainfall patterns? Where and when do clouds form in the atmosphere? To answer such questions, my group analyzes observational data and performs systematic studies with numerical models, with which we simulate flows ranging from the meter-scale motions in clouds to global circulations. We also strive to translate scientific discoveries into improved models for weather forecasting and climate prediction. The same observations and numerical tools that enable new scientific discoveries have the potential to transform modeling of the climate system. Our group is contributing to the development of next-generation models and model components that will enable more accurate predictions of the climate system.
