A simple atmosphere and ocean model of relevance to El Nino
and Southern Oscillation (ENSO) is discussed. Both the
atmosphere and ocean models are two layer, three
dimensional, linear and baroclinic, and generally follow
the Oregon State University coupled general circulation
model. However, the parameterization differs considerably
from previous work...
The Oregon continental shelf waters are typically characterized by four to five major upwelling events that occur between May and October. The upwelled water is rich in nutrients, which fuels an increase in phytoplankton biomass. The onset of El Nino, however, can disrupt the normal physical processes along the Oregon...
Many new research and monitoring projects, developed or initiated during ENSO 1982-83, constituted detailed descriptions of changes in specific taxa or specific processes. However, only a few projects were opportunely started or continued as regional efforts in the eastern Pacific. For those reasons, the information obtained is difficult to compare....
