Application of the Altimetry Data to the Analysis of Water Balance of the Black Sea

Application of the Altimetry Data to the Analysis of Water Balance of the Black Sea We compare the estimates of the flow rates for the Upper and Lower Bosporus Currents obtained by using both the altimetry data on the Black-Sea level and the data of the coastal stations. Earlier, in analyzing the water exchange, it was customary to use the mean sea level computed according to the data of coastal stations located along the coast of the former Soviet Union. It is shown that the seasonal and annual variations of the increments of the mean sea level are qualitatively similar for the data of both types. At the same time, the values of the amplitudes of seasonal variations are noticeably different. The use of the increments of the mean sea level computed according to the altimetry data leads to insignificant changes in the annual water exchange through Bosporus as compared with the values obtained by using the coastal data.

Abstract

We compare the estimates of the flow rates for the Upper and Lower Bosporus Currents obtained by using both the altimetry data on the Black-Sea level and the data of the coastal stations. Earlier, in analyzing the water exchange, it was customary to use the mean sea level computed according to the data of coastal stations located along the coast of the former Soviet Union. It is shown that the seasonal and annual variations of the increments of the mean sea level are qualitatively similar for the data of both types. At the same time, the values of the amplitudes of seasonal variations are noticeably different. The use of the increments of the mean sea level computed according to the altimetry data leads to insignificant changes in the annual water exchange through Bosporus as compared with the values obtained by using the coastal data. However, the seasonal variations of these data are somewhat different. We propose an algorithm for the evaluation of increments of the sea level, which, in authors' opinion, decreases the error in the analysis of water balance.
