Biography

Samantha Hallam completed her PhD in Ocean Climate Science at the National Oceanography Centre, University of Southampton. Her research topic was the impact of Atlantic Ocean variability on tropical cyclones and the northern hemisphere jet stream. Part of the findings show ocean drivers of recent active Atlantic hurricane seasons are found to take two forms: late winter changes in the ocean circulation related to a reduced Atlantic Meridional Overturning Circulation and late spring/early summer changes in the air-sea heat flux. In the subtropical Atlantic the prediction of TC potential intensity is also found to be closer to actual intensity using the average temperature through the top 50m layer (𝑇50𝑚̅) as opposed to SST. 

In February 2021, Samantha joined the Irish Climate Analysis Research Units at Maynooth University working on the ROADMAP project investigating the impact of ocean circulation variability on atmospheric and climate dynamics, including the reconstruction of western boundary currents and Atlantic Meridional Overturning Circulation.
