Basin–Scale Winds

Wind stress over the northeast Pacific is measured from the Quickscat satellite.  Monthly average winds showed conditions favorable to upwelling as early as January 2007.  This is a positive indicator and the chief cause for improved ocean conditions observed in winter and spring 2007 (Figure 30).
