Abstract

El Nino Southern Oscillation (ENSO) phenomena is one of the atmospheric events causing climatic variability Worldwide that demonstrates a teleconnection pattern on a global scale. It influences the whole southern hemisphere and a great part of northern hemisphere beyond countries and continents. The present research investigates the impacts of this phenomenon on precipitation in Shahr-e-Kord region, southwest Iran using Southern Oscillation Index. Monthly precipitation records of Shahr-e-Kord gauging station for a period of 1956-2005 were gathered for the purpose of this study and the results showed that a significant correlation of 0.01 and 0.05 exists for precipi­tation data of several months of the year over specific time periods. This correlation is negative which emphasizes the fact that the El Nino event is usually followed by a wet year and the La Nina phenomenon reduces the precipitation in the region.
