EFFECTS OF SOLAR ACTIVITY CYCLES IN THE ATMOSPHERE OF THE NORTH ATLANTIC AND EUROPE

Considered are results of the spectral analysis of temperature and dendro-chronological data (45 chronologies of which 10 are original collected in different regions of the Kola Peninsula including the Khibiny region and the zone of technogenic pollution in the vicinity of the enterprise Severonikel, the town of Monchegorsk). The spectral analysis results allowed us to single out the basic solar activity cycles (11, 22, 33, and 88—90 years) in climate variations from instrumentally measured temperature and dendrochronological data. It was shown for the first time that the manifestation of solar activity cycles in air temperature and annual tree rings weakens with the distance from the coastline of the North Atlantic—European system, which in turn is a major line dividing the region into two zones of relative stability and spreads from Northern Finland and the Kola Peninsula to the Iberian Peninsula. The results obtained are of principal importance for forecasting climate variations in the zone.
