The Fluctuations And Trends In Odessa Sea Level During The Last 50 Years
Abstract
The oscillations of the Black Sea level by the average annual and monthly values on the stations of the Odessa-port for the entire observation period from 1875 was researched and compared with changes in the last 50 years (1960 and 2010.). The wave nature of the sea level variability with amplitude of 9-10 cm and period of 3-4 years was shown on background trends to rise. The change of the trends on the fall has happened in the second half of the 90s (from 491 cm in 1994 to 481 cm - in 2007). The amplitude of the seasonal sea level fluctuations in Odessa was estimated (13-20 cm) and was detected the appearance of two extremes in 50% of cases. The correspondence of the maximum in sea level of the Black Sea with the years of El Niño indicates the existence in the World ocean of common processes. The abnormally high value of the sea level on the Odessa-port station in 2010 was confirmed the connection with the El Niño in winter 2009-2010.
