Abstract:
The Nearshore Wave Prediction System (NWPS) is currently developed to
provide on-demand, high-resolution nearshore wave guidance to the
coastal forecasters of the National Weather Service (NWS). The
nearshore wave model applied is SWAN (Booij et al., 1999), and
alternatively a nearshore version of WAVEWATCH III (Tolman et al.,
2002). Wave boundary conditions are received from the National Centers
for Environmental Prediction's (NCEP) global WAVEWATCH III model, and
during storm events in the Atlantic and Gulf of Mexico, wave boundary
conditions are ingested from the NWPS implemented at NHC-TAFB domain
from where the official winds are also used, surface currents are
ingested from RTOFS Global and water levels are taken from the
Extratropical Surge and Tide Operational Forecast System (ESTOFS, Feyen
et al., 2013). NWPS produces various types of output, including fields
of integral wave parameters, spectra and individual partitioned and
tracked wave systems. This model guidance is subsequently ingested into
AWIPS to aid in the generation of detailed coastal marine forecasts.
NWPS has been designed to run locally at NWS’s coastal Weather Forecast
Offices (WFOs), covering their forecast domains of responsibility and
is driven by forecaster developed wind grids from the Advanced Weather
Interactive Processing System’s (AWIPS) Graphical Forecast Editor
(GFE). However, servers at WFOs are severely constrain by all the
processes and applications and for this reason NWPS will be installed
on WCOSS, this poses several challenges: the architecture of NWPS must
be changed to fulfill NCO requirements; forecasters will still provide
the wind fields from AWIPS through LDM at their respective HQ and, they
will have the control when NWPS will run on their geographical domain.
Moreover, the NWPS results will need to be transfer to every coastal
WFO via SBN.
