Abstract : The objectives of research carried out during the past year were to understand entrainment processes across density interfaces subjected to differential turbulent forcing; and to develop theoretical and laboratory-based descriptions for internal waves and mixing processes resulting from the interaction between turbulence and stratification. The first part of the study is applicable to the evolution of density step structures observed in the atmosphere and oceans, which consist of turbulent layers separated by density interfaces (Padman & Dillon 1989, J. Phys. Oceanogr., 18, 1458-1462). The second investigation is aimed toward parameterization of processes occurring at the oceanic convective layers, for example, the night-time boundary layer where cooling-induced convection plays a significant role in the generation of turbulence.
