Abstract
Background and Aim: Climatic characteristics and most of its elements play a decisive role in the spatial distribution and formation of environmental behavior of human societies, so that nowadays, studies and investigations of human bioclimate and the use of its various capabilities are the basis of urban, development, settlement, architecture, and tourism planning. Accordingly, the aim of this study is to investigate and analyze human comfort based on bioclimatic models and indicators.
Methodology: The research method is descriptive-analytical. This study was conducted in 2024 in the city of Sisakht, using climatic data such as temperature, relative humidity, wind speed and air pressure for the period from 2006 to 2024. The required data was collected from the Sisakht synoptic station. After collecting data, human comfort or discomfort was analyzed based on the bioclimatic models and indices of Terjung, Baker, nervous stress, and thermohygrometric for different seasons of the year. This analysis included examining the temporal and spatial changes of the indices to determine which month and hours of the day have the most favorable climatic conditions for tourists. Finally, the models and indices were examined and compared to determine the most effective and efficient method for assessing the bioclimatic conditions of the city of Sisakht.
Finding and Results: The results of this study showed that Sisakht has bioclimatic diversity throughout the year, ranging from hot to very cold conditions; during the winter and summer seasons, it is outside the range of bioclimatic comfort, and with the beginning of the spring and autumn seasons, in the months of transition from cold to heat (April) and heat to cold (November), the climate of Sisakht approaches human comfort conditions. In general, spring, with its unique conditions of human comfort, is the best season for environmental activities and tourism in the city of Sisakht. Also, considering the climatic characteristics of the studied area, the Baker method, neurotic pressure, and then the Terjung method are more suitable and reliable in evaluating the bioclimatic conditions of the city of Sisakht than other bioclimatic indicators.
