英文摘要: Response of the Black Sea elevation to intraseasonal sea level changes in the Mediterranean is studied using satellite altimetry data and a linear analytical model. Satellite observations show that the nonseasonal sea level in the Black Sea (η1) is coherent with that in the Aegean and Marmara Seas (η0) but lags behind them by 10-40 days at subannual periods. The observed time lag is mainly due to friction that constrains the exchange through the Bosphorus Strait. Using realistic friction and characteristic η0 forcing in the model, we find that the amplitude of η1 reaches the amplitude of η0 at about 1 year period, and the time lag increases from 10 to 22 days at periods 50-250 days. Freshwater fluxes, atmospheric pressure, and to a smaller extent the along-strait wind also influence the Black Sea elevation, but sea level fluctuations in the Mediterranean appear to be the dominant forcing mechanism. © 2015.
