Abstract
Preliminary experiments in the numerical prediction of large scale
sea-surface temperature anomalies are made using a 10-level primitive
equation model with 300-km horizontal resolution covering a rectangular
basin in the North Pacific. The model is first integrated over an 11-
year period to statistical equilibrium using time dependent wind and
thermal forcing. The monthly normal climatology, generated by the
model in this long term integration, is then used along with observed
sea-surface temperature anomalies to define the initial state.
The results show that inclusion of salinity in the model may produce
more accurate predictions of high latitude cold anomalies. The
most accurate of the predictions removed all of the anomalous diffusion
terms in the governing equations. Data for the observed temperature
anomalies were not available at depth, thus initialization of the
anomalies below the surface was superficial. Consequently, the effects
of vertical advection were not fully realized, indicating a need for
future experimentation with a more accurately defined initial profile
of the anomalies in the initial conditions.
