The article presents the results of a study of the temporal variability of atmospheric circulation in the Arctic region. The classifi cation of atmospheric circulation forms according to Wangenheim — Girs for cold (November – April) and warm (March – October) periods of the year are used. We consider the repeatability of series with one form of circulation for gradations of duration and variability in time of this characteristic, as a parameter of stability of synoptic processes in the region under consideration. As additional characteristics, the horizontal gradients of the pressure field are calculated according to the atmospheric pressure at sea level. Estimates of the variability of the meridional and latitudinal directions of air advection are obtained.
