Tropical Climate Dynamics Lab

About the Lab

Welcome to the tropical climate dynamics research group at Woods Hole Oceanographic Institution (WHOI)! We are interested in atmospheric and oceanic processes in the tropics and their interactions with higher latitudes. We study a variety of topics, including the Inter-Tropical Convergence Zone (ITCZ), marine atmospheric boundary layer clouds, the Madden-Julian Oscillation (MJO), the Hadley circulation, equatorial waves, tropical cyclones, El Niño-Southern Oscillation (ENSO), and tropical-extratropical interactions.  One of our primary goals is to improve understanding of observations of these complex phenomena using a hierarchy of models and observations. With this improved understanding, weather and climate prediction can be guided in the right direction.

We are also involved in science education and outreach, particularly at WHOI and in the local Cape Cod community. From bringing hands-on rotating tank climate science experiments to K–12 and college classrooms to mentoring middle- and high-school students and teachers on research projects, we strive to motivate a generation of future scientists.

We have an opening for a Ph,D, student to start Fall 2025 as a part of the MIT-WHOI Joint Program. The project seeks to better understand cloud structures in and surrounding the southern hemisphere branch of the ITCZ over the east Pacific Ocean with a long-term goal of alleviating the double ITCZ bias.
