Andrew Orr emphasises need for high-resolution modelling in new PCAPS blog

5 December 2024

PolarRES researcher Andrew Orr (British Antarctic Survey, UK) emphasises the need for high-resolution regional atmospheric modelling at grid-spacings of 1-10 km for the Polar Regions in a blog post for the Polar Coupled Analysis and Prediction for Services (PCAPS) project. High-resolution regional atmospheric models are able to better represent key local physical processes that characterise the polar regions, resulting in more accurate and detailed weather forecasts and future climate predictions, which are required by many users. 

PolarRES, a key project in this effort, supports initiatives like the Polar Coordinated Regional Climate Downscaling Experiment (Polar CORDEX) project and PCAPS to advance regional atmospheric modeling. The next step for the PolarRES work will be the completion by the end of 2024 of a set of storyline-based regional climate projections for the polar regions for the 21st-century at an unprecedented grid-spacing of 11 km, which will pave the way for more reliable assessment of the potential social and environmental aspects of climate change.
