How and why might clouds cluster together in the tropics, and what impact does this have on climate? I've worked on this subject with Allison Wing, a professor at Florida State University, as well as Tom Beucler, who was my first PhD student at MIT and graduated in 2019. We have used computer models to simulate and analyze the phenomenon of "self-a...
Do hurricanes require an ocean surface, or even moisture at all, to form and exist? The answer, based on the present climate, might seem like an emphatic "of course!" -- but other climates and vortices on other planets might disagree! A paper from several years ago also found formation of a hurricane-like storm in a completely dry atmospheric model...
How does very cold air form, and how is that process sensitive to a changing climate? The process of Arctic air formation is that by which high-latitude maritime air is transformed, by radiative cooling, into high-latitude continental air, which is much colder at the surface and often has temperature inversions. I've worked on this problem with Eli...
Why does it rain more over even flat islands than nearby ocean areas in the tropics, and what consequences might this have for the climate system? As a dissertation topic, I looked at whether the diurnal cycle of land-atmosphere interaction and convection might be able to explain this island rainfall enhancement. I worked together with advisor Kerr...
How do ice ages begin? How a small glacier, or set of small glaciers, expand to cover much of a continent (which we think happened around 115 thousand years ago) is called glacial inception, and is a fundamental but still largely open problem in climate science. Harvard PhD student Leah Birch was co-advised by Eli Tzpiperman and me, and worked on t...
How do human-caused changes in land surface properties affect the climate? The complexity of the land surface formulations used in climate models often makes it difficult to understand what is going on when we attempt to simulate something like the impacts of land cover change on climate. I have developed a (relatively) simple theory which can be u...
What are some of the nuances of our simplest credible model of planetary climate? Radiative-convective equilibrium (RCE) is this simplest credible climate model, and represents a hypothetical state of the atmosphere-surface system where radiative cooling of the atmosphere to space is balanced by convective heating, mainly by rising warm and moist a...
How do midlatitude weather systems alter the overturning cells of the Tropical Atmosphere? Early in my time as a grad student at MIT, I did a few term papers exploring theories of the Hadley circulation. For a Harvard Journal Club in 2013, I led discussion on a paper about a simple model for the Hadley circulation. See the Code For Numerical Models...
Tim Cronin is a researcher at MIT who studies convection, radiation, and clouds. He works on topics such as self-aggregation of convection, tropical cyclones, cold air formation, diurnal cycle, glacial inception, and boundary layer sensitivity.
Tim Cronin is an Assistant Professor of Atmospheric Science in Earth, Atmospheric, and Planetary Sciences at MIT. The focus of his research is on the role of regional-scale atmospheric dynamics, radiative transfer, and coupled surface-atmosphere interactions in the climate system. He combines pencil-and-paper theory and simplified numerical ...
Former postdoctoral associate from 2017-2021, worked on coupling between clouds, convection, and atmospheric dynamics on tidally-locked rocky expolanets, and on fundamentals of radiative transfer and the runaway greenhouse. Currently assistant professor at Peking University. PhD University of Chicago (2016). dkoll (at) pku.edu.cn.
Timothy Cronin is an associate professor at MIT EAPS who studies regional-scale atmospheric dynamics and surface-atmosphere interactions. He uses numerical modeling to explore topics such as cold air formation, cloud clustering, and thunderstorm enhancement by aerosols.
