The effect of climate change on climate parameters of Takab and Saghez stations in Zarrinehroud Basin via LARS-WG

Excessive use of fossil fuels, the increasing world population and the ever-increasing of industrial activities accordingly to provide welfare and the needs of humans, thereby has been increased the concentration of greenhouse gases, particularly carbon dioxide in recent decades. This increase in greenhouse gases cause a phenomenon called climate change. The purpose of this study was to investigate the effect of climate change on the output of three CANESM2 MPI-ESM-MR and CCSM4 models selected from the CMIP5 model series in the near future (2020-2020) and the future of the future (2070-2099). ) Under the RCP2.6, RCP4.5, RCP8.5 radiation induction scenarios on precipitation, minimum temperature and maximum temperature. To simulate the climatic parameters of the Zarrine River basin, the data of these three models were microscopically compared with the LARS-WG model. According to the evaluation statistics, the MPI-ESM-MR climatic model has better performance than other two models for simulating climatic parameters. Subsequently, by examining the results for all stations, the temperature trend with increasing and precipitation decreased. Saqez Station showed a more intense trend in simulation as the temperature in this station is increased by an average of 0.5 to 1 ° C higher than the Takab station and in the rainfall, with a decrease of 3 to 30 mm, the ratio Shows Takab. Also, the minimum temperature is higher than the maximum maximum temperature at all stations.
