Abstract :
Climate comfort is related to the temperature balance of the human body with its environment. This balance depends on the combination of factors such as: characteristics of the surrounding air, physical activity of the person, ambient temperature, relative humidity, sunlight and wind. The present study was conducted with the aim of investigating the effects that the physiological equivalent temperature can have on urban tourism. For this purpose, the surface of Shiraz city was zoned using the physiological equivalent temperature (PET) index on an annual scale, which is zoned based on 10 observational stations. It was calculated in and around the city with the statistical period from 2000 to 2020. The generalization of the calculated station results to the level of the study was done in ArcGIS environment and using the IDW internalization method. According to the obtained results, the favorable and appropriate climatic conditions for tourism throughout the year in Shiraz city change due to the change of seasons and the change of weather conditions between the northern and southern highlands of the central plain. In general, the pattern of daily changes of the index showed that the period of climatic comfort in Shiraz includes two time periods in late spring and summer. The months of May and September are the only months without cold stress and have the best climatic conditions for attracting tourists, and it is the ideal time based on the PET .April and October with little cold stress and June with little heat stress are ranked second respectively. During the months of December, January, and February, the whole city has severe cold stress. Study the pattern of daily changes of the index showed that the spatial changes of the PET index in the region are mostly influenced by the geographical altitude and latitude
