The Surface Circulation of the Santa Barbara Channel and the Santa Maria Basin Inferred from a Model Simulation (1993-1999) with Data Assimilation
Abstract
The 1993-1999 circulation of the Santa Barbara Channel and the Santa Maria Basin is simulated using the Princeton Oceanic Model. Two numerical experiments are carried out: without and with data assimilation. Wind data from ECMWF data set and buoy data are used in the simulation. The comparison analysis shows that the model result generally agrees with observation and the assimilation of the temperature improves the results. The basic characteristics and seasonal variation of the circulation in this region, such the cyclonic circulation and the convergence and offshore flow at the Point Arguello are shown in the simulation. The analysis of seven-year time series of the model results indicates that there are multiple-timescale variations of the circulation in this region.
