| هدف پژوهش حاضر پیشنمایی تغییرات دما و بارش در شمالغرب ایران تحت سناریوهای SSP مدل NorESM2 است. با بهرهگیری از آزمون تخمینگر شیب سن، دما و بارش شهرهای منتخب طی 2014-1985 روندیابی شد. سپس با استفاده از نرمافزار SDSM6.1، پارامترهای مذکور برای دوره پایه (2014-1985) شبیهسازی و برای سالهای 2043-2015 پیشبینی گردیدند. برای ارزیابی عملکرد مدل، از شاخصهای خطاسنجی MSE، RMSE و MAE استفاده شد. استفاده از سناریوهای جدید SSP برای پیشبینی پارامتر مهم اقلیمی دما و بارش در شهرهای مطرح در زمینه گردشگری ایران، نوآوری این پژوهش است. نتایج آزمون شیب سن حاکی از روند صعودی دمای حداکثر در همه شهرهای مورد مطالعه در سطح اطمینان 99% بهجز شهرهای تکاب و سردشت بود. طبق نتایج روندیابی بارش، تکاب و مراغه در سطح اطمینان 99% دارای روند کاهشی معنادار و جلفا و ماکو در سطح اطمینان 95% دارای روند افزایشی معنادار بودند. بر اساس نتایج مدلسازی، بارش در همه شهرهای مورد مطالعه در فصل بهار افزایش خواهد داشت که بالاترین درصد افزایش مربوط به جلفا خواهد بود (20%). بارش در تابستان و پاییز کاهش خواهد یافت که بیشترین درصد کاهش برای مراغه پیشبینی شد (33%). دمای حداکثر در همه شهرهای مورد مطالعه بهویژه در ماههای سرد افزایش خواهند داشت که میزان این افزایش تا ℃2 خواهد بود. | ||

| The aim of the current research is to forecast temperature and precipitation changes in northwest of Iran under SSP scenarios of the NorESM2 model. By using Sen's slope estimator, the temperature and precipitation of selected cities were trended during 1985–2014. Then, using SDSM6.1 software, the mentioned parameters were simulated for the base period (1985–2014) and predicted for 2015–2043.To evaluate the performance of the model, the error measurement indices MSE, RMSE and MAE were used. The innovation of this research is the use of new SSP scenarios to predict the important climatic parameters of temperature and precipitation in prominent cities in the field of Iranian tourism. The results of the test of Sen's slope estimator indicated an upward trend of the maximum temperature in all the studied cities at the 99% confidence level except Takab and Sardasht cities. According to the results of precipitation trending, Takab and Maragheh had a significant decreasing trend at the 99% confidence level, and Jolfa and Mako had a significant increasing trend at the 95% confidence level. Based on the modeling results, precipitation will increase in all the studied cities in spring, and the highest percentage of increase will be in Jolfa (20%). Precipitation will decrease in summer and autumn, and the highest percentage of decrease was predicted for Maragheh (33%). The maximum temperature will increase in all the studied cities, especially in the cold months, which will be up to 2 °C. | ||
