Dr Christine McKenna

Profile

I joined the Institute for Climate and Atmospheric Science (ICAS) in October 2019 as a Postdoctoral Research Fellow. I worked with Amanda Maycock on the EU-funded CONSTRAIN project, which aimed to better understand and constrain uncertainty in future projections of climate change. My work focused on changes in large-scale atmospheric circulation – in particular, the North Atlantic Oscillation (NAO) – and using multi-model Large Ensembles to quantify uncertainty in these changes. Most recently I looked at the role of future changes in the NAO for changes in European winter precipitation and, also, the impact of NAO and East Atlantic Pattern variations on storm impacts including wind gusts, extreme daily rainfall, and storm surge. 

Before coming to Leeds, I studied for my PhD at the British Antarctic Survey and University of Cambridge. In my PhD I used an intermediate global circulation model, IGCM4, to look at how the large-scale atmospheric circulation changes in response to Arctic sea-ice loss. In particular, I examined whether the response is sensitive to different regions or magnitudes of sea-ice loss, and the relative roles played by tropospheric and stratospheric mechanisms. I also looked at the influence of atmospheric internal variability with regards to uncertainty in simulated atmospheric responses to sea-ice loss.

In March 2023, I moved into the private sector to work as an atmospheric scientist for JBA Consulting, a flood risk consultancy. I maintain a Visiting Researcher status within ICAS to facilitate ongoing research links and future collaborations.
