The late Quaternary records of alkenone sea surface temperature (SST) in the Japan and California margins showed orbital‐scale anti‐phase SST variations between the two margins. This east‐west seesaw‐like change agreed well with the long‐term El Niño‐Southern Oscillation (ENSO) behavior predicted by the Zebiak‐Cane ENSO model [ Clement et al. , 1999] as regards both the timing and frequency during 0–60 ka and 120–145 ka, and is attributed to the precession‐controlled change in tropical ENSO behavior. This anti‐phase SST change was not clearly demonstrated during 60–120 ka. This finding suggests that the influence of tropical climatic dynamics on the mid‐latitude North Pacific varied in response to glacial‐interglacial cycles.
