The Global Ensemble Ocean Wave Forecast System (GEOWaFS)
provides wave forecasts from 21 wave models run simultaneously using
winds from NCEP's Global Forecast Sytem GFS (control member) and
from the Global Ensemble Forecast System GEFS (20 perturbed members).
Forecasts extend from 0h to 240h, and are provided for a global domains in
a spherical grid with 0.1 x 0.1 degree resolution. Forecasts are run 4x daily at
the 00, 06, 12 and 18Z run cycles.
The US National Weather Service also generates operationally a combined wave-height
ensemble product in partnership with the Fleet Numerical Meteorology and Oceanography
Center (FNMOC) of the US Navy. The combined wave ensemble data are at the NFCENS page.
Forecast products provided below from the NCEP wave ensemble system consist of global
maps of statistical parameters derived from the 21 wave ensemble members, as follows:
|Mean & Spread
||Means and Spreads in the ensemble
||Contour maps where parameters exceed 7 threshold values
||Probability maps where parameters exceed 7 threshold levels
The viewer controls allow you to select from the last 5 days
at the run times of 00Z, 06Z, 12Z, and 18Z. Spaghetti and Probability maps
include a control to select a threshold value for the selected parameter.
