Abstract

We performed investigations of synoptic variability of bottom and surface currents, the flow rate of the Mzymta River, and the wind speed measured with high resolution (10 min periodicity) in the coastal zone of the city of Sochi in May 2009, 2010, 2011, and 2012. Based on the measurements, a Fourier spectral analysis and harmonic analysis were carried out for both low-frequency and high-frequency components of the variability of the current velocities and wind speed. The analysis revealed a similarity of the structures of the main oscillation periods for the currents in the low-frequency spectrum and significant fluctuation periods for the currents in the high-frequency range. In addition, we studied the internal waves generated by the river plume.
