Abstract

North Atlantic Oscillation is a efficacious pattern of variation of common gyration in the confine of torridness external and is one of the main operative of climate's elements such as temperature and precipitation that contain extra economic and social effects on department of energy, husbandry, industry, transport and hygiene. in this research monthly givens appertain to index of surface`s pressure of oscillation in the North Atlantic Ocean and annual precipitation in twenty years statistics period for 37 stops from mild northern of Iran used for account correlation coefficient without retardation and too as monthly ,bimestrial and quarterly .And in the outrance negative and slated positive phases of NAO and droughts and wet years. maid method in this research is using of analytic statistics person correlation coefficient ,spearman , analysis of component`s precipitation process and index of North Atlantic Oscillation(NA ,polynomial regression and nonlinear regression. results of chosen stops of mid northern of Iran and index of North Atlantic Oscillations there is negative correlation and meaningful. Particularly in January, February, March, April, May, October, November and December and there is this linkage especially in the droughts and wet years. and too specified that stops of western section of though out zone show more correlation from eastern zone stops to pressure of oscillations on the surface of North Atlantic Ocean. with these results we can say North Atlantic Oscillations is one of important and effective index on the precipitation of mid northern of Iran.
