Abstract. I report the discovery of a low frequency temperature oscillation in the eastern North Atlantic (NA), which was signi®cantly correlated with the Southern Oscillation Index (SOI) in the tropical Paci®c, but led the latter index by a number of months. This discovery is signi®cant, because it demonstrates a link between the tropical Paci®c and the high northerly latitudes which cannot readily be explained in terms of El NinÄ o/Southern Oscillation (ENSO) feedbacks from the tropics, and opens up the possibility that ENSO and temperature anomalies in northerly climes, may actually have a common origin within, or even external to, the global climate system. Key words. Meteorology and Atmospheric dynamics (ocean-atmosphere interactions) á Oceanography: general (climate and interannual variability) á Oceanography: physical (air-sea interactions)
