On the influence of Atlantic Multidecadal Oscillation and North Atlantic Oscillation on the temperature regime of the Black Sea region

Abstract

To assess the interannual-interdecadal changes in surface air temperature anomalies in the Black Sea coastal zone associated with global climate change, long series of measurements of surface air temperature near Cape Kikineiz and the city of Yalta on the Southern Coast of Crimea were used. Estimates of polynomial trends and long-term fluctuations in surface air temperature anomalies are obtained. Trends in average annual and seasonal surface air temperatures are compared with changes in the North Atlantic Oscillation and Atlantic Multidecadal Oscillation indices. The results indicate the existence of long-term fluctuations in the regional surface air temperature anomalies, seasonally synchronized with global meteorological processes.
