In this research the data relating to Sea Level Pressure (SLP) Oscillations index in North Atlantic and annual precipitation have been studied for East Azerbaijan Province in a time period of 43 years aiming at the calculation of coefficient of correlation and calculation of wet years and droughts. The main methodology being used in this research is the analytical statistics (Pearson and Spearman correlation coefficient methods, analysis of linear and polynomial trend components). The results of this study indicate that is being weak negative correlation (but meaningfully specially in intensive wet years and droughts) between annual precipitation and NAO index in Tabriz, Ahar and Jolfa stations.
