this analysis was conducted on 31 synoptic stations in iran. initially, the mann-kendall test was administered in order to analyse the trend of alterations of these two components over time and the results suggest that 16% of the stations show significant relationship with annual precipitation (positive and negative). more stations showed significant relationships between sunspots and minimum a...

Changes in the mean and the extreme values of hydroclimatic variables are two prominent features of the future climate. Therefore, simulating the climatic behavior of Shandiz catchment area, an important tourist area in the northeast of the country, will play an important role in identifying the climate condition and potential vulnerability of these areas in the coming decades of climate ch...
