Trends of long-term changes are estimated for air temperature, precipitation and snow accumulation in northern Eurasia, for the area of Arctic sea ice area and for the Arctic Oscillation index – for 1979–2009. For large Eurasian regions the significant regression dependence was found for the meteorological conditions from the sea ice area changes (negative relationship) and from index AO (positive relationship). Influence of Arctic Oscillation on the meteorological conditions prevails in the Western and Central Siberia, the effect of changes in sea ice area prevails in Eastern European Plain and the North-East Siberia. Regression dependence of snow accumulation from air temperature and precipitation throughout insignificant, correlation between long-term variability of Arctic Jscillation index and sea ice area is not significant too.
