Abstract
Today, due to global warming, the frequency of heat waves has increased and the severity and continuity have left destructive impacts in the nature. Accordingly, the main objective of this paper is to identify heat waves in Zabol city and their continuity, severity and frequency. For this purpose, we received the daily Maximum and minimum temperature data of the Zabol station from 1961 to 2015. Then the daily average temperature was calculated and the databases formed in MATLAB software. The threshold of 95th long percentile of everyday climate of the year used to identify heat waves. The results of the analysis show that in this region, the low-heat waves have a higher incidence, and fewer excessive heat waves have occurred. The most durable heat waves occurred in the study area during the period from 1971.5.23 to 1971.5.30 and from 2013.7.19 to 2013.7.30 with continuity of 8 and 12 days, respectively. The results shows heat waves as climate hazards have been increasing in the statistical period and have grown more in recent years.
