Reliable weather forecasts and future climate predictions for the polar regions are required by many users. The users in these regions are increasingly asking for more granulated, higher-resolution weather forecasts and climate predictions, which presents a major challenge for the current and next generation of atmospheric models. The World Weather Research Programme (WWRP) aims to address this challenge through the Polar Coupled Analysis Prediction for Services (PCAPS) project. Dr Andrew Orr - who is a climate scientist at the British Antarctic Survey, a member of the PCAPS steering group, one of the coordinators of the Polar Coordinated Regional Climate Downscaling Experiment (Polar CORDEX) project, and an investigator for the Polar Regions in the Earth System (PolarRES) project - reflects on how high-resolution regional atmospheric modelling is being used to address these challenges and help improve our understanding and decisions related to the polar regions.
