Abstract: The x-y-t, two-layer ?-plane numerical model developed by Hurlburt (1974) is used to examine the upwelling system off Peru. The region off Peru from 14 to 15°30's is one of strong and persistent upwelling. The most distinctive ...

Abstract: The Naval Research Laboratory (NRL) has developed a global, relocatable, tide/surge forecast system called PCTides. This system was designed in response to a U.S. Navy requirement to rapidly produce tidal predictions ...

Abstract: The National Ice Center relies upon a coupled ice?ocean model called the Polar Ice Prediction System (PIPS) to provide guidance for its 24?120-h sea ice forecasts. Here forecast skill assessments of the sea ice concentration ...

Abstract: Arctic air masses have direct impacts on the weather and climatic extremes of midlatitude areas such as central North America. Arctic physical processes pose special and very important problems for global atmospheric models ...
