Abstract :
The majority of the planning of urban development, construction, habitat, architectural, and tourism expansion is perfectly assured when it is accompanied by weather cognition and the use of its various potencies. Considering the importance of the topic, in this research, a spatial and temporal analysis of changes in climatic parameters and identifying prone areas in Ilam province was carried. In this research, climatic data of precipitation, temperature, relative humidity and wind speed from six synoptic stations were used to investigate the trend analysis in the 30-year period (1992-2021) based on the Mann-Kendall test. Next, using Baker's climatic index, the degree of climatic comfort was determined for each month. Then, monthly climatic comfort zoning maps of Ilam province were prepared using geostatistics technique. According to the results, during the studied period, there has been a significant increase in temperature, while there has been a slight decrease in the amount of precipitation. The results of Baker's climatic indix showed that the months of April, May, October, November and March are prone to climatic comfort. According to the results, Darreh-Shahr and Lomar have the greatest potential for climatic comfort in the months of transition from heat to cold (October and November) and cold to heat (April and May). In general, according to the climatic zoning map, the northern and eastern cities of Ilam province have higher climatic comfort in spring and autumn. On the other hand, in the winter season, the southern and border cities (Mehran and Dehlorn) have a comfortable climate. The results of this research provide suitable information for improving living conditions, including health, safety, productivity and comfort of people, as well as suitable areas for residence at different times of the year.
