My main research interests are associated with understanding the coupling between different regions of the atmosphere, this coupling often being associated with waves on a number of temporal and spatial scales. My work involves the use of a range of remotely sensed observations from radar and satellite instruments and data from reanalyses and other models.
At present I am particularly interested in:
- VHF radar remote sensing of convection and the potential impact of convection on mixing between the stratosphere and troposphere
- Stratosphere-troposphere exchange in the Southern Hemisphere
- Mesosphere-Lower Thermosphere dynamics above Antarctica, primarily related to understanding the wave-driven circulation at these altitudes using the Scott Base MF radar
- Internal gravity wave observations with radar and satellite systems
- Antarctic ozone depletions dependence on planetary scale waves
- The impact of changes in the total solar irradiance on the chemistry and dynamics of the middle atmosphere
