Climatic Comfort Potentials in the View of Tourism in Ilam Province Using Equivalent Temperature Index (ETI) and Discomfort Index (DI)

The purpose of present research is to assess Ilam provincial climate in the view of tourism using Equivalent Temperature Index Discomfort Index. In this regard, it was used dataset of National Meteorology Organization and statistics of General planning and management Department, Ilam provincial stations (& stations) from the date of their opening to the end of 2016. Then, collected data were considered by two respective indices. Discomfort Index will calculate the rate of human discomfort in relation to thermal factor using air temperature, relative humidity (RH) and wind rate. Equivalent Temperature Index will assess common effects of temperature on living organism in relation to air temperature and evaporation. Results obtained from Ilam provincial tourism climate by means of Equivalent Temperature Index showed that the lowest and highest annual scores were related to Ilam and Dehloran cities, respectively. Results of Discomfort Index (DI) showed that the lowest and highest DI scores related to Ilam city in January and Dehloran city in July were 614 and 28.8, respectively. Based on obtained results, Ilam province had two different spatial and temporal spans for tourism. Tow that, in regard to tourist attraction, if northern region has optimal conditions in one season, at the same time, there is no optimal conditions in southern regions.
