On the basis of NOAA-ESRL (http://www.esrl.noaa.gov/psd/) data it is shown that the cold anomalies averaged on the area of the Black Sea have a well-defined annual course with a maximum during the autumn period. The composites of warm and cold anomalies of sea surface temperature for the period of 1982-2014 describing the distribution of anomalies on the area of the sea are displayed. It is shown that the cold anomalies, more long-lasting in comparison with the warm ones, reach the greatest development in the central and western deep-water parts of the sea. They are characterized by fast onset and slow attenuation. The cold anomalies in the central part of the sea during the autumn period with temperature falls by 4–5°C and lifetime of more than a month are marked out. The distribution of the anomalies in the near coastal areas of the sea changes within the year. Positive anomalies in the northeastern Caucasian-Crimean region of the sea during the autumn-winter-spring period are controlled by heat transfer of the Basic Black Sea Flow. The histograms of the temperature anomalies for the central deep-water part of the sea characterizing asymmetry of distribution of the cold and warm anomalies and showing prevalence of repeatability of the long-lasting cold anomalies over the warm ones are constructed. In contrast, for the north-western coastal area of the sea the warm anomalies are the most developed and repeated
Keywords: annual variation, anomaly composites, long-lived anomaly, histograms, sea distribution features
