The Southern Oscillation (SO) including cold (La Nina) and warm (El Nino) phases is one of the most important oceanic-atmospheric event affecting the climate on earth. Recent studies proved that climate changes display considerable effects on the components of the hydrologic cycle. In this context, understanding the mechanisms controlling the variability of SO will also help us to understand the systems controlling the climate changes. The large-scale oscillations (pressure fluctuations) due to atmospheric movements within the hydrologic cycle are the climate anomalies having periodical characters. Therefore, the effects of the climate changes and climate anomalies on the water resources should be studied, and their future conditions should be observed and investigated. The purpose of this study was to determine the relationships between Southern Oscillation and the precipitation data of Black Sea Region of Türkiye. In order to find out the relationships, the homogeneity analysis methods of Standard Normal Homogeneity Test, Pettitt Test, Buishand Test, Von Neumann Test and Run Test were applied on the precipitation data of the Black Sea Region. As a result, the correspondence between the breaking years obtained from the homogeneity analyses and the warm/cold phase years of SO was determined as 59%.eninfo:eu-repo/semantics/openAccessSouthern OscillationPrecipitationHydrologic CycleClimate AnomalyClimate ChangeConference Object
