These impacts are caused by variable zonal winds through their effects on meridional Ekman transport and air-sea fluxes. While the SST response is well known on an interannual (ENSO) to decadal (PDO) scale, the response of sea surface salinity (SSS) is less known due to relatively sparse observations. The SSS response originates in the western Pacific and is concentrated along the North Pacific subarctic front, reaching a few tenths of psu in the upper 100 m, as demonstrated by satellite SSS, Argo salinity data, and model simulations. SSS anomalies, in contrast to SST anomalies, behave like passive tracers that are advected eastward in the North Pacific Current across the whole basin and, unexpectedly, sometimes intensify to the east. After reaching the eastern boundary, they continue predominantly southward along the California coast, remaining detectable by satellite SSS all the way to the southern tip of the California peninsula.
