Abstract
The long-period variations in the climatic position of the Arctic front in the North Atlantic have been investigated. It is found that oscillations of the Arctic front latitude near Greenland occur with main periods of ∼80, ∼44, and ∼22 years; this finding indicates possible relationship of these oscillations with the solar activity and variations in galactic cosmic rays. It is shown that the secular oscillations of the Arctic front latitude can be responsible for the amplitude modulation of the 11-year harmonic in sea-level pressure variations in the North Atlantic.
