Abstract

Heat stress is the most important climate feature of Khuzestan province and the most influential atmospheric phenomenon on manpower in the study area. In this study, in order to investigate the temporal and spatial heat stress affecting the manpower of military units based in Khuzestan province, First, a special exploratory study was conducted on the subject and method of research, and then the physiological equivalent temperature index was compared with the standard effective temperature index and the physiological equivalent temperature index was found to be more appropriate for this research. Data from 12 synoptic stations in the study area with a statistical period of 30 years (1990-2020) have been used to extract the index. Data on climatic parameters including wind speed, temperature, relative humidity, water vapor pressure and cloud cover were received daily from the Meteorological Organization and GIS software was used to draw the map. The research findings show that the trend of index changes in the last 30 years has been increasing and is projected to reach 18,088 in 2030. The stations of Abadan, Omidieh, Hindijan and Bostan in the west and south of the region are the most days with heat stress and the most unfavorable place for manpower in military units in the region. In terms of time, July and August are the worst times for the use of manpower in the region, respectively, and the months of November and March have the best conditions for the use of manpower in military units based in Khuzestan province.
