My research interests are in the physics of rainstorms and atmospheric circulations in a changing climate. I am particularly interested in what environmental factors control the temporal and spatial scales of rainstorms, how will the characteristic scales of rainstorms change in a warmer climate, and how the collective effects of individual rainstorms, in turn, shape Earth's climate.

June 2021: Prof. Da Yang leads a C3.ai project on using machine-learning methods to improve the forecast of the MJO.
Feb. 2021: Our new paper "A Shallow Water Model for Convective Self-Aggregation" was published in the Journal of the Atmospheric Sciences.
July 2020: Our new paper "Amplified Madden-Julian Oscillation Impacts in Pacific-North America Region" was published in Nature Climate Change.
"A study from UC Davis found that in the tropical atmosphere, cold air rises due to an overlooked effect — the lightness of water vapor."
May 2020: Our new paper "The Lightness of Water Vapor Helps to Stabilize Tropical Climate" was published in Science Advances. This paper proposes that an overlooked effect of water vapor has significant impacts on Earth's energy balance. If you like simple models, check out our companion paper "The Incredible Lightness of Water Vapor" published in Journal of Climate.
Apr. 2020: Our new paper "Four Theories of the Madden-Julian Oscillation" was published in Review of Geophysics. This paper summarizes and compares four leading MJO theories.
