Figure 4. Illustration of strong interannual variation in California Current transport, from the CalCOFI data set (after Roessler and Chelton, 1987). Cold years (e.g., 1954) are typified by strong equatorward transport of subarctic (low salinity) water. Warm years (1958, 1959) are typified by weak equatorward transport. Most of the interannual variation is coupled to ENSO events in the equatorial Pacific (Pares-Sierra and O'Brien, 1989). 345
