The North Atlantic Oscilation (NAO), The Arctic Oscilation (AO) and Forest Fires in Lithuania

Abstract

In Lithuania in the period 1992–2015, decreasing trends were recorded for the annual number of forest fires (significant at p≤0.05) and the annual burned area (not significant). In the research of the connection between forest fires and the North Atlantic Oscillation (NAO) index, the highest values of Pearson correlation coefficient (significant at p≤0.01) were recorded for the annual number of fires and NAO index for June (0.589) and summer (0.538). With the Arctic Oscillation (AO) index, the highest value was recorded for the annual number of fires and AO index for June (0.486).
