Surface meteorological records from Ocean Weather Stations are used to characterise interannualchanges in the intensity of synoptic and subsynoptic processes over the North Atlanticmid-latitudes during the period from early the 1950s to 1990s. Individual 3-hourly data werefiltered to separate ultra-high frequency variability (0–2 days) and synoptic scale variability(2–6 days). Joint consideration of the intensities at these 2 scales in mid-latitudes makes itpossible to construct parameters which are highly correlated with the North Atlantic Oscillationindex. In high latitudes, intensities of synoptic and ultra-high-frequency processes are stronglynegatively correlated on interannual and decadal time scales. This phenomenon is discussed inthe context of interaction between high and mid-latitudinal synoptic variability.DOI: 10.1034/j.1600-0870.2000.d01-6.x
