Analysis of temperature changes in East Azerbaijan province with a climate change approach Using the SDSM model

Temperature change in the future, which is very important in terms of agriculture, development and health, can be one of the consequences of climate change and global warming. Knowing how it can be a significant help to the agricultural sector and development issues and managers decisions. One of the effects of climate change is the increase in temperature in some parts of the world, including Iran, so it is necessary to study this phenomenon. The purpose of this study is to know the rate of temperature change in the next period (2015-2073) compared to the base period (1987-2015) in stations of East Azerbaijan province. In this study, the trend of temperature changes in Maragheh, Miyaneh, Jolfa and Tabriz synoptic stations with the help of SDSM statistical microscale exponential model under three scenarios of optimistic, intermediate and pessimistic radiation induction during the next two periods (2016-2044) and the middle future (2073-2045) has been examined. For this purpose, the observational data of the mean maximum and minimum temperature in the base period have been entered as input to the model. The output results of the exponential microscale model showed that temperature changes in future periods have an increasing trend in all studied stations. For example, in the Tabriz synoptic station, in the pessimistic scenario, the average temperature will increase by 4.17 ° C in the future, and in the optimistic scenario, the increase will be 1.85 ° C. According to the results of this study, the highest temperature increase in the middle pessimistic scenario compared to the base period for the middle synoptic station by 4.51 ° C and the lowest temperature increase in the near future medium scenario at Maragheh station by 1.31 ° C has been observed. It is suggested that politicians and planners pay attention to this increase in temperature in the fields of urban architecture, agriculture, energy management, etc.
