Stephan Fueglistaler

Geosciences/Atmospheric and Oceanic Sciences


My approach to research may be best described as "stumbling" over interesting and puzzling data, followed by a quest for identification of the key processes that usually takes much longer than anticipated. As such, I have been working on aspects of cloud microphysics (with a pinch of chemistry), radiation and large-scale dynamics; with a focus on the so-called Upper Troposphere/Lower Stratosphere (UT/LS) region. Currently, I am working with my group on theoretical approaches to understand atmospheric water vapour, on Kelvin waves in the tropics, and on a mechanistic understanding of the interplay of large-scale dynamics and ozone chemistry, and its feedback on UT/LS temperatures through radiative effects.
