Abstract
A computer simulation model of the phosphate, phytoplankton and zooplankton dynamics in Monterey Bay was examined and modified. The model is driven by four forcing functions expressed as annual cycles of upwelling velocity, incident solar radiation, mixed layer depth, and mixed layer temperature. An alternate upwelling index was developed based on the local wind field. A revised radiation index is employed based on the generation of both advective fog and low stratus cloud cover common during upwelling on the California coast. Analysis of the model's response to sinking and advection of
phytoplankton was examined. The importance of seasonal increases in predators was introduced as a controlling factor in the seasonal growth of zooplankton. The model is able to predict the seasonal trends of phosphate, phytoplankton, and zooplankton throughout the year.
