I am interested in all aspects of atmospheric fluid dynamics, with a particular focus on troposphere-stratosphere coupling via convection and the Tropical Tropopause Layer (TTL). My PhD thesis used idealised numerical simulations to model turbulent transport, wave generation and hydration of the TTL by overshooting convection. The problem was modelled as a buoyant plume penetrating into a stratified layer.

My current research deals with coupling between large-scale stratospheric dynamics, such as the Quasi-Biennial Oscillation, and tropical convection patterns in the troposphere, such as the Madden-Julian Oscillation. The QBO is predictable on much longer timescales than the “weather” seen in the troposphere, meaning its tropospheric teleconnections have important implications for subseasonal-to-seasonal predictive skill. We use high-resolution aquaplanet simulations to develop mechanistic understanding of the coupling processes.
