If early warnings are not issued, they can take an area by surprise and have a devastating impact. This lesson aims to improve the ability of marine forecasters to forecast extreme marine events related to high swells. It does so by providing background information on winds and waves, and presenting a process for monitoring and forecasting high swell events using a variety of data. These include ASCAT scatterometer wind data and the ECMWF Extreme Forecast Index (EFI) product, wh ...PermalinkThis lesson introduces forecasters to the physical processes and impacts of tropical cyclone storm surge.

Therefore, manual skills in determining swell height and period are needed in order to cross-check or correct model predictions in cases of poor or unresolved model forecasts of wi ...PermalinkThis is the fourth lesson in our series on open water waves. As deep-water waves approach the coastline, they encounter shallower water and begin to interact with the sea floor while evolving into shallow water waves.
