Ocean Currents

Ocean currents can vary in geographic scale.  They not only dominate climate forcing but are of considerable interest to local coastal communities.  Smaller-scale eddies and tidal features in particular are key components to not only shipping and fishing industries, but for predicting how pollutants can flow in events such as the Deepwater Horizon BP oil spill.  Surprisingly, such data is currently not available to most of the television broadcast market.

WorldWinds has worked diligently to blend multiple ocean current models into a single array for North American ocean currents that cover all basins, gulfs, and near-coastal locations.  Multiple models from the National Center of Environmental Prediction (NCEP) and the U.S. Navy are used to build the total currents field.  A series of blending algorithms were created in order to mesh together a global coverage model and regional models without there being any distinguishable edges in model boundaries.  This 48-hour forecast is available daily at 10km resolution.
