Wind-driven variations in a SSH (cm) at station K2 (red line) and b absolute geostrophic volume transport (Sv) down to a depth of 4000 dbar to the east of K2 (black line). Time series smoothed by 15- and 35-month running mean filters are indicated by thin and thick lines, respectively. Positive values in panel b indicate northward transport. For comparison, the observed SSH at K2 and the North Pacific Index (NPI) are shown by blue and green lines, respectively, in panel a. The NPI was smoothed by a 15-month running mean filter and normalized by the standard deviation
