Wieloletnia zmienność opadów w atlantyckim sektorze Arktyki

In this study the multiyear variability of the annual and seasonal sums of precipitations in the Atlantic sector of Arctic were studied. The analysis were caried out on the base of 8 meteorological stations localized above the 60O N of latitude. The meteorological data were mainly obtained from GHCN (Peterson T. C et. all 1998) and NACD (Frich P. et. all., 1996). It was stated that at the large majority of the meteorological stations the greatest part of annual sums of precipitation appear in autum and the lowest one in spring. The annual as well as seasonal sums of precipitation were distinguised by considerable variation but their 5-years running of standarized value hardly ever exceeded 1 standard deviation. The coefficients variability counted in the running 11-years periods indicate on decrease of variability of the annual sa well as sprinf and winter sums of precipitation in the greatest part of Atlantic sector of Arctic.
