AOSN-II August 2003

Data collected by the research vessel Point Sur from 2-6 August 2003 has been analyzed to provide an estimate for the current synoptic conditions. This estimate of synoptic conditions provides the initialization conditions for the Harvard Ocean Prediction System (HOPS) model simulations.

The model simulation uses data from 2-6 August 2003 in the nowcast (initial conditions). Data from Woods Hole Oceanographic Institution and Scripps Institute of Oceanography autonomous underwater vehicles (gliders) are assimilated into the ongoing simulation.

Atmospheric forcing for the PE model is derived from the US Navy operational COAMPS (Jim Doyle) at 3km resolution. Recent winds have not been upwelling favorable. Winds are generally light and variable, leading to relaxation conditions. During relaxation conditions, upwelling along the coast diminishes or vanishes and warm off-shore water moves on-shore.
