Abstract:

The goal of this project was to use observations from the Eastern Boundary Currents EBC field experiment and a quasigeostrophic model to describe and predict the dynamical balances of nonlinear eddies observed in the California Current System CCS. The synoptic, 2-D, quantitative estimates of horizontal shears, vorticity, and divergence resolved by our observations are new, and they have revealed a mesoscale eddy field that is strongly nonlinear, with Rossby numbers of O1. Model reconstruction of one of the anticyclones confirms the large Rossby number and nonlinearity. The model results suggest that the anticyclones are submesoscale coherent vortices.
