Deep profiles of the ocean current fine structure (the NE Black Sea, June 2011)
Internal waves and near-inertial motions interacting with the mesoscale eddies and the Rim Current
Northward component of the current velocity over the continental slope in the northeastern
Black Sea in July 2007. Thin red lines indicate location of the profiler during the survey
Near-inertial oscillations in seasonal thermocline off the Gelendzhik Bay in the Black Sea on July 2007
Sequential vertical profiles of the temperature are shifted by 2°C along X axis.
Lower part from 30 m to 250 m is not shown.
Estimates of vertical momentum and heat exchange
The mean gradient Richardon number <Ri> = < N2 > / <Uz2> as estimated from the profiler data on July 11-13, 2007.
The thick black line is the vertical profile of the median values <Ri>. Red line indicates <Ri> = 0.25.
Red dotted line indicates <Ri> = 1.The coefficients of vertical eddy viscosity and eddy diffusivity
v = A0/(1+aRi)2 +A1, k = v / (1 + aRi) + A2
