Results

The model was initialized with results from the NPac model,
and run for 1996 through 2002 with NCEP forcing. The resulting
sea surface height anomaly are shown below (left) compared to
TOPEX (right). Click image for animation. Eddies of realistic size
and seasonality are produced, as are El Nino related interannual variations.

The model was then re-run with MM5 forcing for the years 2001 and 2002.
Results were compared at the locations of GLOBEC LTOP stations along the
Seward Line in Alaska. Both cases have a realistic seasonal pattern in
temperature and salinity. Though they overestimate the freshness of water at
the surface inshore,using MM5 does improve the results.

Run with NCEP forcing:
Temperature Salinity
timeseries

Temperature (Celcius) sampled at 4 model locations approximating stations 1, 4, 9, and 13 along the Seward line.

timeseries

Salinity (ppt) sampled at 4 model locations approximating stations 1, 4, 9, and 13 along the Seward line.
