Extended Data Figure 7: Intra-annual variation in upwelling trends.
From: Intensification and spatial homogenization of coastal upwelling under climate change
Multimodel mean daily offshore Ekman transport for 1950–1999 (blue curve) and 2050–1099 (red curve) averaged over the three highest latitudes in the CalCS (a), CanCS (b), HCS (c) and BCS (d). Positive and negative temporal trends in the daily Ekman transport occur when the red curve is above and, respectively, below the blue curve. These increases and decreases in upwelling transport are also highlighted by the red and, respectively, blue shading between the curves. The onset and termination of the upwelling season correspond to the times of the year when the daily Ekman transport first and, respectively, last reaches zero.
