Climatic Analysis in Western Iran (Case Study: Sanandaj Synoptic Station)

Climate change is one of the major challenges facing mankind today. Various climatic parameters such as temperature, precipitation and wind in one place are factors that influence the climate of that area and Their knowledge determines the climate of that region. Occurrence of phenomena such as sudden increase or decrease of temperature, rainfall and velocity and direction of wind over one or more years can be attributed to climate change in that region. One of the most important climate issues in recent years has been the opinion of researchers and even heads of governments and organizations due to their effects on political, social, economic and other activities. In our country this issue has been less attention, but in recent years has been the result of research and conferences To Study Climate Change in Kurdistan Province Average, Minimum, Maximum Temperature and Average Precipitation and Mean, Minimum, Maximum Wind Speed and Direction, Sanandaj Station during the Years 1960-2017 Obtained from the Meteorological Organization and set in time series and analyzed using Mann-Kendall nonparametric test. In this research, using the above model, the type and timing of changes in these elements have been identified. The results of the data analysis show that the onset of most changes was sudden and of both trend and fluctuation. Average and minimum temperature parameters have negative trend and maximum temperature parameter has positive trend and show negative trend precipitation and the mean and minimum wind speed parameters have a negative trend and the maximum wind speed parameter has a positive trend and the mean wind direction parameter has a negative trend.
