My research is to develop a unified understanding of how the tropical atmosphere works, and the key is to understand moist convection—cumulus clouds and thunderstorms. Moist convection dominates vertical energy transport in the lower atmosphere, and its interaction with atmospheric circulations forms the basis of a spectrum of atmospheric phenomena across wide temporal-spatial scales. I am now thinking about the following questions that help advance our understanding of multiscale convection.

How do mesoscale [O(100 km)] cloud systems cluster together?

What sets the propagation speed of synoptic scale [O(1,000 km)] tropical waves?

What is the nature of the planetary scale [O(10,000 km)] Madden-Julian Oscillation (MJO)?
