Description
Summary:Northwest of Iran has plant, animal and environmental varieties because of its geographical location. Therefore, alternate weather may have irreparable outcomes in numerous environmental sectors. In the prevailing research, it was turned into consideration to investigate the droughts that with inside the northwestern vicinity of Iran all through a 30-yr statistical period (1987–2016) that occurred, the usage of the records of fifty-five synoptic, climatology and rain gauge stations was evaluated with inside the positioned area. Using the SPI in a 12-month period, 360 maps had been produced for drought severity and month-to-month droughts. Then, the maps had been transformed into records, and the calculations associated with its descriptive information consisting of the common center, well-known circle and ellipse had been calculated on 4236 cells. The consequences of the month-to-month evaluation of droughts and moist duration intensities all through 360 months confirmed that the chance of susceptible moist durations with inside the important elements and extreme droughts with inside the southern half of the vicinity is better than different situations. More extreme droughts arise on this vicinity.
