Nearshore Wave Prediction System (NWPS) provides on-demand, high-resolution
nearshore wave model guidance to U.S. coastal Weather Forecast Offices (WFOs),
triggered in real time by forecast wind grids prepared and submitted by the individual
offices. NWPS is driven by forecaster-developed wind grids produced in AWIPS, and
wave boundary conditions from the operational WAVEWATCH III model. The model
core used is the spectral wind-wave model SWAN. Wave-current interaction is included
using surface currents from the Real-Time Ocean Forecast System (RTOFS-Global).
Tides and storm surge are accounted for using the Extratropical Surge and Tide
Operational Forecast System (ESTOFS, extratropical conditions), or the probabilistic
model P-SURGE (tropical conditions). The computational grids have a nearshore
resolution of 1.8 km-200 m. NWPS produces fields of integral wave parameters and
individually tracked wave systems. These are available in gridded binary (GRIB2) files
at hourly intervals out to 144 h. Forecast cycles are available at the synoptic times at
which they were requested by the individual WFO.
