In this study, the effect of meteorological variables and occurrence Foehn phenomena on forest fires are investigated using a combination of time series observations analysis and simulation data in Zagros Mountains. The high-resolution WRF numerical model with two nested domains 5, 15 km spatial resolution used to clarify the effect of meteorological variables on forest fires. The results indicate, the value of Angstrom Index or the risk of fire in the windward side stations is more than leeward side stations and the value of Fosberg’s Fire Weather Index is variable depends on the wind velocity. Also, results showed that the seasonal and dry conditions of the region starting from late May month cause drying of fields and pastures in the area and provided the conditions for fire. The conditions prevailing in the region indicate the absence of the Foehn phenomena in the region.
