Abstract
Analysis of information on forest fires in the Arkhangelsk region showed bursts of forest fires in the period 1959–1961, 1972–1973, 1997–2001 and 2010–2011. To establish the regularities of the solar activity influence (Wolf numbers) on forest fires, statistical studies were carried out. The distribution of Wolf numbers in terms of magnitude has a regular character and practically does not change over the months of the year. Correlation analysis about the statistical dependence of the factors was used to test the hypothesis. A certain interdependence between meteorological factors, of the local population life and the number of fires has been noted. An assessment of the interconnection degree between the area and number of forest fires and solar activity has been carried out. A weak relationship has been established between solar activity and the number of forest fires in the forest fund. It is recommended to use Wolf numbers to predict the degree of fire hazard only in conjunction with other factors.
