Future research of climatic parameters facing urban areas (Case Study: Isfahan City)

Climatic changes in Iran have been associated with increasing weather anomalies such as sudden and heavy rains, decreasing rain, increasing the average temperature of some cities, and causing widespread drought. Therefore, in this research, an attempt is made to evaluate the impact of climate changes on water-sensitive cities, especially the city of Isfahan, and to predict these changes. The research method in this article is applied based on its purpose and exploratory based on its nature. Also, Demartin's model has been used to measure the dryness factor of Isfahan. In the following, using document and library studies and with the help of information from synoptic stations of Isfahan city and using SDSM software, first the important effects of climate have been measured and then the effects of climate change on this city in the future have also been discussed. The findings of this research indicate that the city of Isfahan is going through very critical conditions in terms of climate. If the process of these changes is not curbed, we will see huge changes in the city of Isfahan in the not-too-distant future. According to the results of Demartin's method, it can be seen that Isfahan is located in a dry and desert region and climate changes strongly affect it. In addition, the results obtained from simulations in SDSM software, which were evaluated with NCEP data (rainfall and temperature), showed that Isfahan City will witness a warming of 2 degrees Celsius by the year 2050, which will affect the entire climate. It will cause the precipitation patterns and the other 26 variables of the Meteorological Organization to collide. This is despite the fact that if measures are not taken to curb the increase in temperature (based on the increase in greenhouse gases) by 2050, this increase will take an upward trend and will increase up to 4 degrees Celsius in 2080.
