Combined NCEP/FNMOC Wave Ensembles Product
Due to scheduled maintenance of our backup supercomputer, there will
be no web site updates to our model graphics pages from
Sunday 23 July through
Thursday 27 July (estimated).
The production models are running normally on our primary
supercomputer and our production FTP server and NOMADS data server are
being updated. The only impact is to our post-processed graphical
products displayed from this server. We apologize for the
The Combined NCEP/FNMOC Wave Ensembles (NFCENS) Product consists of a combination
of significant wave height (Hs) data from the NCEP wave ensemble system, and from the
wave ensembles run by the US Navy Fleet Numerical
Meteorology and Ocenographic Center (FNMOC). The product combines outputs
from a total of 41 wave ensemble members. A detailed description is provided in
Alves et al. (2013)
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.
Products from the NCEP wave ensemble alone, which also include in addition to wave
heights, peak period and wind speed/direction data are at the GEOWAFS page.
Forecast products provided below consist of global maps of statistical parameters
derived from the 41 combined NCEP/FNMOC wave ensemble members, as follows:
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.
