摘要: Many processes are known to influence the distribution of sea surface temperature (SST) fronts in Eastern Boundary Current Systems (EBCS), including wind forcing, mesoscale activity, flow instabilities and flow-topography interactions. Here, we used satellite observations quantify relative importance one these processes, eddy on SST gradients EBCS. Eddies characterized by large gradient anomalies all At end upwelling season, eddy-induced dominant components full offshore 300 km from coast, especially regions high activity. Comparisons between California System indicate that migration eddies plays a significant role seasonal widening region frontal associated with anticyclonic largest within 400 shore, while signature cyclones can extend for up 700 coast.
