Hannah L. Croad

Hannah L. Croad is a researcher at the Department of Meteorology, University of Reading, and a corresponding author of a 2024 study on sea-ice coupling in Arctic weather forecasts. Her work focuses on improving atmospheric boundary layer representation in coupled models, particularly under dynamic Arctic cyclone conditions.

• Key Research Areas: Meteorology, Climate Science, Sea-Ice Dynamics, and Numerical Weather Prediction.
• Affiliations: University of Reading and European Centre for Medium-Range Weather Forecasts (ECMWF) collaborations.

Scientific Contributions include comparative analysis of dynamic vs. static sea-ice models in the ECMWF Integrated Forecasting System (IFS). Her 2024 study demonstrated that dynamic sea-ice coupling improves predictions of ice-edge movement and near-surface temperature biases in Arctic cyclones, though thermodynamic coupling introduces initialization shocks. She emphasizes the importance of surface roughness and heat flux parameterizations in marginal ice zones.
