Abstract
In this study, to evaluate the temperature hazards of Khuzestan province, first the matrix of maximum daily temperature data for the warm period of the year of the stations from May 15 to October 6 (156 days) for a total of 24 years (2013-2017) is equivalent to 3744 days was extracted. In order to distinguish hot, very hot, and super hot days, the average and long-term standard deviation of the total station data during the period of 3744 days were calculated and the standardized maximum daily temperature index was calculated for all stations. Days with an index anomaly of less than 1, between 1 to 1.5 and more than 1.5 were designated as hot, very hot and super hot days, respectively. The application of cluster analysis by cumulative stacking method on the temperature data matrix of 3744*1144 and drawing a zoning map using (GIS), showed four temperature risk zones (low risk, medium risk, high risk, and very high risk) in the province: 1) Low risk area: with the northwest-southeast trend of the province, including mountainous and relatively highlands, which are located on the Zagros highlands at the eastern and northeastern extremities; 2) Medium risk zone: low altitude belt adjacent to Zagros mountain range in the southeast, East and North; 3) High-risk area: low-lying central, eastern and western lands of the province; 4) Very high-risk area: most of the central and western regions of Khuzestan.
