Abstract

The phenomenon of climate change has caused a change in the intensity and frequency of extreme phenomena, especially extreme rainfall. Spatiotemporal analysis of extreme precipitation is very important in order to increase the flexibility of socio-ecological systems and their infrastructures under climate change. This study examines the spatiotemporal changes of precipitation characteristics with temperature changes. For this purpose, Spearman's non-parametric test has been used to evaluate trends in three precipitation indices (maximum 3 and 6-hour precipitation and total annual precipitation) and two temperature indices (maximum and minimum annual temperature) in 26 synoptic stations located in Iran. In this research, statistics and information from 34 to 70 years old (from 1951 to 2020) were used. The trend of the data was checked at a significance level of 95%. The results showed that the maximum rainfall of 3 and 24 hours in Gorgan station has a positive trend, but the index of total annual rainfall in this region has a negative trend, also the maximum rainfall of 3 and 24 hours in Ahvaz, Isfahan and Semnan stations also has a significant increasing trend, and these areas are prone to flash floods. Also, the results showed that the increase in maximum 3-hour and 24-hour precipitation at higher temperatures in a limited number of stations leads to an increase in annual precipitation, and most stations show a decrease in precipitation with increasing temperature. Also, the maximum temperature in all stations (except Shahrekord and Birjand) has increasing changes, which indicates the warming of the air in summer.
