Abstract
The formation and break-up or erosion of stratification is a major process in all natural and man-made lakes, which controls to a large extent the functioning of their ecosystems. The key challenge here is the specific role of shear generated and convective turbulence in the formation/destruction of stratification and their interactions with internal waves. Three aspects of hydrodynamics, i.e. the dynamical state, the physical mechanism and the energy level are very important elements in understanding problems of turbulent mixing and the formation of vertical thermal stratification. The result of the stratification is the formation of the seasonal thermocline.
