Figure 2: Satellite-derived surface current map for December 2000 from the method of Lagerloef et al. (1999), with improved techniques developed by Bonjean and Lagerloef (in preparation). Satellite data include December 2000 TOPEX/Poseidon sea surface height anomalies plus the mean December climatology for wind stress and SST. Data have been smoothed zonally with a 21 degree Gaussian filter.
