Abstract

The purpose of this study was to determine the role of Foehn wind on forest fires in Gilan province and forest fire prediction methods. For this purpose, fire statistics of Gilan forests were selected during the statistical period (2002 - 2006) and synoptic maps of sea level were investigated during fire. The results of this study showed that the two cyclone patterns of northern Europe and migratory high-pressure have been effective in the Foehn phenomenon of the southern Alborz slopes. By studying the first method of prediction (Factor B of Angstrom risk)  of fire caused by the Foehn phenomenon it is concluded that the migratory high-pressure system is the main cause of Foehn and fire in the region.
