Turbulence
The turbulent transport of
momentum, mass and heat in the Mohid can be calculated in a simplified
way using constant diffusion coefficients. The user can also use
simplified parameterizations to compute variable diffusion coefficients.
However in the vertical due to the sharp gradients usually present
in this direction, the user can compute the evolution of turbulent flow
properties in a more realistic way using the ke
GOTM model . This model gather the
most known and well tested parameterizations of the ke
model applied to ocean and costal waters. This set of parameterizations
goes from the well known Mellor & Yamada (1974) parameterization to the
most uptodate ones like Canuto et al. (2001).
