Antarctic Coastal Winds
This project aimed to improve observational knowledge of winds along the Antarctic coast and use this to both evaluate the current state-of-the art climate models and help make improvements for the next model generation.
I am a polar climate scientist whose research focuses on Antarctica’s coastal winds: their variability, drivers and representation in climate models. A goal of this research is to understand and improve projections of coastal winds for the coming decades. A realistic representation of these winds in model simulation is needed as they have a key role in Southern Ocean circulation, including transport of warmer water towards ice shelves. They also influence sea ice and coastal ecosystems.
In my doctoral research I investigated the winds responsible for emission of mineral dust from the remote central Sahara. I used infrared satellite measurements to characterise dust storms, showing the central role of convective storms and the effect of orography upon low-level jets in this dust source region of global importance.
