Current Research

The climate response to the Weddell Sea Polynya (2021 – 2023)

My current research focuses on the Weddell Sea Polynya, assessing the response of the local and global climate, funded by the European SO-CHIC project. I have used HadGEM3 and the HighresMIP PRIMAVERA data set to understand the ocean and atmospheric response to the polynya. Additionally, this data is being used to evaluate the differences between model resolutions in modelling the polynya and sea ice loss in the region.

Past Research

The climate response to Antarctic Sea Ice Loss (2017-2020, University of Exeter).  

My PhD research focused specifically on the modelled impacts of Antarctic sea-ice loss, through a multi-model CMIP5 analysis, in addition to Unified Model coupled and atmospheric only simulations via HadGEM3 GC3.1. The thesis aimed to answer the question of how Antarctic sea ice loss impacts the global climate system through various modelling techniques, in addition to highlighting the differences between these techniques and limitations associated with them. I also setup and run simulations for the Polar Amplification Modelling Intercomparison Project (PAMIP). This PhD was part funded by the University of Exeter, alongside the NERC Real Projections Project.
