Calculation of the vertical shear (Source File: shear.F90)
The (square of the) shear frequency is defined as
It is an important parameter in almost all turbulence models.
The - and -contributions to are computed using a new scheme
which guarantees conservation of kinetic energy for the convertion
from mean to turbulent kinetic energy, see Burchard (2002a). With this method,
the discretisation of the -contribution can be written as
. The -contribution is computed analogously.
The shear obtained from (37)
plus the -contribution is then used for the computation of the turbulence
shear production, see equation (146).
