The data of the current measurements in the Caucasus and Crimea region
s of the Main Black Sea Current (MBSC) are analysed. The main quasihar
monical components of the MBSC time temporal variability and their par
ameters are obtained. The main period of the meanders both for Caucasu
s and Crimea regions is 6 days. The mathematical approximation of the
MBSC time variability is correlated with experimental data.
