Investigation of the Effects of North Atlantic Oscillation and Arctic Oscillation on Samsun Precipitation

Global atmospheric indices are effective on many hydrometerological parameters. North Atlantic Oscillation and the Arctic Oscillation is one of oscillations that act on Turkey. In this study, the relationship between the annual and seasonal precipitation data obtained from the Bafra, Carsamba, Samsun, Ladik and Vezirkopru meteorological observation stations in the province of samsun was investigated. As a result of the research, significant correlations were determined between atmospheric indices and seasonal and annual total precipitation. A significant portion of the correlations obtained is seen as a negative correlation with winter precipitation. The precipitation formed under the influence of positive and negative phases of atmospheric indices was determined and it was determined that the precipitation formed by the negative phase was more than the positive phase.
