What we have analyzed in the article is the spatial structure of the surface air temperature and precipitation amount fields in the Black Sea Region. Spatial correlation method is applied to reveal teleconnections between surface air temperature and precipitation measured at the meteorological stations of the region from one hand and globally averaged surface air temperature and atmospheric circulation indices from the other hand. Atmospheric circulation indices North Atlantic Oscillation (NAO) and Oscillation «North Sea Northern Caspian Sea» (NCP) determine to a great extent regional temperature and precipitation regime. The goal of the current research is to establish probable causes and mechanisms influencing regional climatic variations and examining of possible connections of the latter with the global climate change. It is demonstrated that relations between air temperature and precipitation at particular stations in the region and global temperature are weak and ambiguous. At the same time, temperature and precipitation regimes are affected by changes of phases of NAO and NCP. It means that global warming has no direct effect on the regional climate. More probably, global warming influences the regional climate through the changes in the atmospheric circulation pattern in the particular region.
