Figure W1. Alongshore wind stress at NOAA NDBC buoy 46050 (a transformed version of the similar Newport wind stress is used to fill gaps), years 1985-2003. The wind stress is calculated following the method of Large and Pond (1981). Gray bars denote time periods where high quality in situ data is available. |

Figure W2. Alongshore wind stress as in Fig. W1, convolved with an 8-day exponential decay, as recommended by Austin & Barth (2002). This filtered version of the wind is highly correlated with the amount of subsurface isopycnal deflection during upwelling. Blue highlighted areas denote fully upwelled conditions. |
