摘要: Simultaneous satellite-derived observations from 2002 to 2009 are used quantify the relation between sea surface temperature (SST) fronts and ocean winds in California Current System (CCS). An edge-detection algorithm is applied SST generate monthly maps of frontal probabilities. Empirical orthogonal decompositions reveal that seasonal evolution CCS strongly related coastal alongshore wind stress. The development remarkably different north south Cape Mendocino, however. While cape extend for hundreds kilometers coast peaking during summer fall, when upwelling stronger off northern Oregon, region Mendocino characterized by high activity spring a much narrower band close coast.
