Physical Basis for Forecasting Strong Wind Events in the Antarctic Coastal Regions

The data set generated in this project is a long (10 years) climate model simulation, with the data over the Antarctic coastal region extracted. A subsidiary data set is episodes of strong simulated surface winds, particularly in the Casey region. From the abstract of one of the referenced papers: A...
