Abstract

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.
