The influence of North Atlantic Oscillation (NAO) variability over climate of France is investigated by several authors. In this paper, the centers of action approach are applied to study spring precipitation (March to May) variability over France, taking into account variations in the components of NAO; (i) the Azores High (AH) and (ii) the Icelandic Low (IL) pressure systems. Our results show that the north-south shifts of the Azores High has significant impact on interannual variations of spring precipitation over France, there being more precipitation when the Azores High shifts southward versus when it is northward. The present study showing that when AH. This article demonstrates that when the AH system moves towards south there is relevant moisture and hot air ascends from the Atlantic Ocean and enter into France. We construct a regression equation for spring rainfall over France in which the AH latitude and Arctic Oscillation are independent variables and it explains 23 percent of the variance of precipitation during 1981-2016.
