This study analyzes the Impact of the Nino Index Fluctuations on the Annual Rainfall in Jordanduringthe period 1960-2014. Several appropriate statistical techniques are used in the analysis of annual rainfall in a sample of rainfall stations, including: Moving Averages, Accumulated Sums, Linear Regression, Correlation.The main results of this study suggest significant relationship between periodicities in both; the Niño index and annual rainfall in Jordan, especially in the northern and central,regions where most of the annual rainfall is associated with Mediterranean depressions. The relationship is weak and insignificant in the south and east where instability conditions and khamasin depression contribute more to the total annual rainfall.Short periodicities of four years where found in annual rainfall associated with similar periodicities in el-nino.
