This web page gives access to animations of continuous hindcasts.
These hindcasts have been run after the fact with
archived wind and ice fields. The entire data set has been (re-) generated
with WAVEWATCH III version 2.22 (see changes page).
Presented are the wave heights (Hs) and peak periods (Tp) at three hour
intervals. The animations start with a cold start of the model, and thus the
first month(s) show the model spin-up behavior. Particularly, the period maps
for the global model for Feb. 1997, shows that the global model needs
approximately 2 weeks to spin up its Pacific swell properly. Corresponding
binary wind and wave data (including peak directions) are available at the
ftp site at
three hour intervals.
CAUTION: The animation files are 3 to 6 MB
in size. It will take considerable time to download such a file, depending
on the speed of your internet connection. It may be worth while to download
the files to local resources before viewing them.

Remarks: For 2000 and 2001, these hurricane archive data were obtained with
reduced time resolution wind fields from a partial archive of GFDL winds and
should therefore be considered mostly as illustration. Data for several months
are not presented here as no hurricanes occured in these months. For 2002,
hourly wind fields have been used, and the archive has been generated using
the full NCEP archive. Starting with the 2003 hurricane season, this archive
is generated automatically like for all other models.

Unlike for the NAH model, this archive is generated automatically from its
