Generally, I am interested in the interaction of "small-scale" phenomena with large-scale dynamics. How do the two influence each other? To what extent are the small-scale phenomena parameterizable, that is representable to the large-scale without being explicitly simulated? To that end, I am involved in diagnosing and developing parameterizations as well as general efforts at improving climate models. Regionally, I focus on Arctic climate, though I still do some research on tropical climate.
Some specific topics that I am interested in include:
