Comparative analysis of the long‐term variability of winter surface temperature in the Black and Aegean Seas during 1982–2004 associated with the large‐scale atmospheric forcing
Abstract Satellite and reanalysis data for the period 1982–2004 were used to study the long‐term variability of the winter‐mean sea surface temperature (SST) in the Black and Aegean Seas and its connection with the major atmospheric forcing: surface air temperature (SAT), surface wind and North Atla...

Abstract Satellite and reanalysis data for the period 1982–2004 were used to study the long‐term variability of the winter‐mean sea surface temperature (SST) in the Black and Aegean Seas and its connection with the major atmospheric forcing: surface air temperature (SAT), surface wind and North Atlantic Oscillation (NAO) and East Atlantic‐West Russia (EAWR) teleconnection patterns. In spite of some differences, the general tendencies of SST variability in both basins are similar. The major climatic event (i.e. SST decreases below the climatic mean followed by the sharp increase of SST, occurred during the period 1986–1999) and its connection with the atmospheric forcing are evident both in the Black and Aegean Seas. During the investigated period, the south‐western wind regime occurred over the Black Sea and the north‐eastern wind regime over the Aegean.
