WebMay 17, 2024 · The general Ekman momentum approximation boundary-layer model (GEM) can be effectively used to describe the physical processes of the boundary layer. However, eddy viscosity, which is an approximated value, can lead to uncertainty in the solutions. In this paper, stochastic eddy viscosity is taken into consideration in the GEM, and … WebEkman ( 1905) also analytically described the development of the Ekman boundary layer from rest. Within the framework of this model the complete analytical description of the dynamics of the Ekman current generated by an arbitrarily varying wind was derived in terms of explicit Green’s function by Gonella ( 1971 ). fc蛋白质

A two-dimensional modified semi geostrophic model is used to study the evolution of oceanic fronts in the presence of vertical mixing. The parameterization used for mixing is an elevated constant value of vertical viscosity and friction; hence the Ekman layer acts as a surrogate mixed layer, with, however, vertical shear allowed ...
