Research Interests


I study the interaction between atmospheric heating/cooling such as is caused by convection or radiative absorption and the tropical large-scale circulation. For this purpose I perform simulations with climate models in idealized settings, and analyze existing simulations from the Climate Model Intercomparison Project as well as reanalysis and observational datasets. The focus of my current work lies on the influence of convective organization in the tropical rainbelts on the mean meridional circulation.

Furthermore, I am interested in more general climate problems such as the state-dependence of the climate response to radiative forcing, the climate response to periodic radiative forcings, the influence of meridional gradients in optical depth on climate, and the change of the tropical large-scale circulation with global-mean surface temperature. In the past, I have worked on several topics related to planetary science such as climate instabilities under strong radiative forcings, the emergence of very warm climates, Moist Greenhouse states, the initiation of a Runaway Greenhouse, climates of slowly rotating planets and climates of planets orbiting two suns.
