| Summary: | Antarctic sea ice plays key roles in modulating Southern Ocean weather and climate processes. Accurate representation of sea-ice properties is one of the keys for improving predictive skill in polar atmospheric forecasts. However, sea-ice representation is relatively basic (i.e., static sea-ice properties throughout the forecast period and/or with an unrealistic, prescribed thickness/snow cover) in widely-used global and regional forecast models. Poor representation of sea-ice properties in numerical weather prediction (NWP) models may increase errors in forecast surface and near-surface parameters. Although operational weather forecasting centres are increasingly using global coupled atmosphere-ocean-ice models to replace atmosphere-only models for short-term (10 day) weather forecasting, the influence of sea ice on such forecasting has yet to be fully quantified, especially in the Southern Ocean. To address this gap, a polar-specific version of the Weather Research and Forecasting model (Polar WRF) is ... |
