Research interest

PhD project
Title: The quasi-biennial oscillation in a warming climate
Supervision: Marco Giorgetta, Ulrike Niemeier, Bjorn Stevens

In my PhD project I investigate how and why the quasi-biennial oscillation (QBO) of the zonal wind in the tropical stratosphere may change in a warming climate. To tackle this question I use high resolution simulations with the global circulation model ICON, which explicitly resolve convection as well as gravity waves. This enables a direct simulation of the QBO without the need for relevant parametrizations, which are needed in coarser resolution models and which are accompanied by overwhelming uncertainties, preventing a conclusive answer about the QBO characteristics in a warming climate so far.

Further interests
1) Dynamics of the QBO and its response to external forcings (e.g. volcanic eruptions or geoengineering)
2) General circulation in the stratosphere and its response to external forcings (e.g. volcanic eruptions or geoengineering)
3) Dynamic coupling between the stratosphere and the troposphere
