英文摘要: Non-smoothed yearly temperature records with minimal statistical uncertainties are constructed for winter and summer of the period 1950-2000 in two areas in the Aegean Sea, for the sub-surface layer of 80-120 m, and two areas in the Black Sea, for the sub-surface layer of sigma-theta isopycnals between 14. 5 and 15. 4. The specific areas are selected mostly because of the dense hydrographic-data coverage they have during the period 1950-2000. Two trend regimes appear in both Seas: a period of decreasing sea temperatures from the early/mid 1960s to the early/mid 1990s and an apparent warming afterwards. Trends in sea temperatures correlate with trends in the North Atlantic Oscillation (NAO) and partly the East Atlantic West Russian (EAWR) indexes, but the signs of NAO and/or EAWR cannot sufficiently justify the winter-to-winter temperature changes in the entire study area. In examining the wind flows in the sea-level-pressure maps for characteristic winters in which local peaks in the sea-temperature records occur, we identify particular sea-level-pressure structures that are not accounted for by the typical North-Atlantic or East Atlantic-West Russia positive or negative dipoles. In addition, there are winters when the Siberian High induces local maxima in sea-temperatures in the study area. A spectral-coherence analysis of the unfiltered winter sea-temperature and the corresponding teleconnection NAO/EAWR records, shows that common spectral and coherence peaks exist at ~5-6, ~9-10 and ~15-17 years. © 2012 Springer-Verlag.
