Abstract
ABSTRACT

In conducting this research, 15 stations with 30-year statistics (1993-2022) were selected in order to evaluate and determine the disadvantages of heat and cold and its effect on the military forces in southern Iran.

Then, data related to climatic elements including dry air temperature, relative humidity, wind speed, cloud cover and saturated vapor pressure were received from the Meteorological Organization on a daily basis. In this research, the MEMI model, which is one of the thermo-physiological heat balance models, was used among the climate comfort indicators.

The results of PMW, PET and SET indices showed that the highest thermal comfort conditions are in the months of January to May and the lowest in the months of July to September. Mahshahr station has good comfortable conditions for 6 months of the year and Bandar Deir station has bad conditions for the military forces for 1 month. Bushehr airport station has very severe thermal stress conditions in September, October and November, and Abadan station has cold stress conditions in January, February and March.

generally; Due to being located in low latitudes and high temperature fluctuations, the southern coasts of Iran have very high heat stress from late spring (June) to early autumn (September). In the two seasons of autumn and winter, the amount of heat stress is reduced, and in these conditions, the southern coasts are at the threshold of comfortable and cool temperatures. As we go from the eastern coast of the Persian Gulf to the western coast, the level of comfort will increase and the heat stress will decrease, and the conditions will be more suitable for military activities and operations.
