Tourism Climate Potential Associated of Semnan Province by Using Physiology Equivalent Thermal (PET)

Iran from tourism point of view is carried to account among the five superior countries of the world. Therefore, information from attractions and natural efficiencies especially climatically viewpoint in the scope of Iran Geography enjoying a well deserved importance. In this research, in order to study the potentials of tourism area in Semnan Province, by applying the PET indicator has been used from climatically parameters of average dry temperature, relatively wet average, wind speed average, steam pressure average, and the cloudy rate of Semnan Synoptic stations, and that of Shahroud and Biarjmand during the statistic course of 1992-2004. The result of this study shows all stations in May mounth and in October, the station Semnan, Shahroud, Garmsar, in September Bearjmand and shahrood and, in April, Garmsar and in June in Byarjmnd of months that are having the best conditions from the point Comment comfort climate and climate are very suitable for tourism have. all stations, the months of July and August, a different degree of thermal stress is low until moderate exist.
