Hamadan has been formed from interconnected neighborhoods dating back more than a hundred years. The center of neighborhood in Hamadan that known as “Chaman”, provide convenient conditions for residents in severe cold winter of Hamadan; autumn and spring winds, and hot summer with intense sunlight. This space allows the residents to establish social interactions and access to adjacent commercial, religious, cultural and health services. The aim of this study is to investigate the correlation between the Chaman space and climate by climatic analysis of indigenous open spaces in Hamadan. After that, data analysis was done using SPSS software. The research method is a field survey using 4158 questionnaires that were evaluated in ten main neighborhoods of Hamadan in the middle of the seasons of one year at three turns in the morning, noon and evening. Regarding the correlation between temperature, thermal comfort and age; thermal comfort is higher at older ages. The feeling of satisfaction with humidity in the female is twice that of the male. The chance of thermal comfort in the spring, assuming the amount of other variables are constant, is 12.77 times the chance of thermal comfort in winter. The chance of thermal comfort in summer, assuming the amount of other variables are constant, is 17.14 times higher than that factor in winter. Also, the chance of thermal comfort in winter, assuming the amount of other variables are constant, is 7.63 times the chance of thermal comfort in autumn.

This article attempts to examine the appropriate time for tourism in the cities of Sistan and Baluchestan province, based on the physiologic equivalent temperature index (PET). The PET index is one of Rayman's software outputs, which is used to explain the tourism climate in Zahedan, Khash, Saravan, Zabol, Iranshahr and Chabahar cities. First, daily data (10957 days), air temperature, cloudiness, water vapor pressure, wind speed and relative humidity of meteorological stations of these cities were collected (1986-2015). The results of RayMan inferred in the form of daily climatic calendars. According to the monthly percentage of non-stress days (thermal comfort), the results showed in Apr (Zabol and Iranshahr, 67%), May, June, Jul and Sept (Zahedan, 28-90%), Oct (Saravan 87%), Nov (Iranshahr 87%), Des, Jan, Feb and Mar (Chabahar, 42-95%) have the best conditions for the presence of tourists. The best conditions for tourism in Zahedan (May and Sept), Khash (May, Sept and Oct), Saravan (Apr and Oct), Zabul (Apr and Sept), Iranshahr (Apr and Nov) and Chabahar (Dec, Jan, Feb, Mar and Apr) are estimated to have the highest percentage of non-stress temperature days.

The present study was conducted with the aim of explaining the relationship between the quantitative factors of degree of enclosure and the temperature difference (the difference between the average temperature of the passages and the average temperature of the city at the same time) in the historical passages of the city of Meybod. This research is applied in terms of purpose and descriptive-analytical in terms of method. The dependent variable was the temperature difference of historical passages with the average temperature of the city and the four variables of length, width, height of the body and the degree of enclosure of the passage were considered as independent variables. The statistical population is 90 passages in the historical context of Meibod city. The way of choosing the passages was random and based on their share from each neighborhood of the entire network of passages in the historical context of the city. Correlation tests, linear regression and Pearson's correlation test were used to measure the relationship between the quantitative factors of degree of enclosure and temperature changes. The results indicate that the two components of enclosure degree and wall height with beta of 0.634 and 0.623 at a significance level above %95 have a signinificant and direct relationship with the temperature difference of historical passages and city temperature. According to the findings it can be concluded that there is no signinificant relationship between the length and width of the passages and temperature changes in the city, while there is a significant relationship between the height of the wall and the degree of enclosure of the passages and temperature changes.
