		+	===== 3. Mean Flow Model =====
		+
		+	This module contains the definitions of the most important mean flow variables used in geophysical models. In GOTM, these are
		+
		+	• the mean horizontal velocity components,U and V
		+
		+	• the mean potential temperature,θ, (or the mean buoyancy,B)
		+
		+	• the mean salinity,S
		+
		+	Each variable Φ can be decomposed into a mean value and a perturbation:
		+
		+	Φ = <Φ> + Φ'
		+
		+	Due to the one-dimensional character of GOTM, the state-variables listed above are assumed to be horizontally homogeneous, depending only on the vertical z-coordinate. As a consequence, all horizontal gradients have to be taken from observations, or they have to be
		+	estimated, parameterised or neglected.

		+
		+	Because of this routine following steps are triggered:
		+
		+	- The model is updated and the output is prepared
		+
		+	- Air - sea interactions (flux, SST) are computed
		+
		+	- Time step is performed on mean flow equations (momentum, temperature)
		+
		+	- Some quantities related to shear and stratification are updated(e.g. shear number, buoyancy frequency)
		+
		+	- Turbulence is updated depending on what turbulence model has been specified by the user
		+
		+	- Results are written in the output files
