!!****  *TURB_VER_THERMO_FLUX* -compute the source terms due to the vertical turbulent
!!       fluxes.
!!
!!    PURPOSE
!!    -------
!       The purpose of this routine is to compute the vertical turbulent
!     fluxes of the evolutive variables and give back the source 
!     terms to the main program.	In the case of large horizontal meshes,
!     the divergence of these vertical turbulent fluxes represent the whole
!     effect of the turbulence but when the three-dimensionnal version of
!     the turbulence scheme is activated (CTURBDIM="3DIM"), these divergences
!     are completed in the next routine TURB_HOR. 
!		  An arbitrary degree of implicitness has been implemented for the 
!     temporal treatment of these diffusion terms.
!       The vertical boundary conditions are as follows:
!           *  at the bottom, the surface fluxes are prescribed at the same
!              as the other turbulent fluxes
!           *  at the top, the turbulent fluxes are set to 0.
!       It should be noted that the condensation has been implicitely included
!     in this turbulence scheme by using conservative variables and computing
!     the subgrid variance of a statistical variable s indicating the presence 
!     or not of condensation in a given mesh. 
!
!!**  METHOD
!!    ------
!!      1D type calculations are made;
!!      The vertical turbulent fluxes are computed in an off-centered
!!      implicit scheme (a Crank-Nicholson type with coefficients different
!!      than 0.5), which allows to vary the degree of implicitness of the
!!      formulation.
!!      	 The different prognostic variables are treated one by one. 
!!      The contributions of each turbulent fluxes are cumulated into the 
!!      tendency  PRvarS, and into the dynamic and thermal production of 
!!      TKE if necessary.
!!        
!!			 In section 2 and 3, the thermodynamical fields are considered.
!!      Only the turbulent fluxes of the conservative variables
!!      (Thetal and Rnp stored in PRx(:,:,:,1))  are computed. 
!!       Note that the turbulent fluxes at the vertical 
!!      boundaries are given either by the soil scheme for the surface one
!!      ( at the same instant as the others fluxes) and equal to 0 at the 
!!      top of the model. The thermal production is computed by vertically 
!!      averaging the turbulent flux and multiply this flux at the mass point by
!!      a function ETHETA or EMOIST, which preform the transformation from the
!!      conservative variables to the virtual potential temperature. 
!!     
!! 	    In section 4, the variance of the statistical variable
!!      s indicating presence or not of condensation, is determined in function 
!!      of the turbulent moments of the conservative variables and its
!!      squarred root is stored in PSIGS. This information will be completed in 
!!      the horizontal turbulence if the turbulence dimensionality is not 
!!      equal to "1DIM".
!!
!!			 In section 5, the x component of the stress tensor is computed.
!!      The surface flux <u'w'> is computed from the value of the surface
!!      fluxes computed in axes linked to the orography ( i", j" , k"):
!!        i" is parallel to the surface and in the direction of the maximum
!!           slope
!!        j" is also parallel to the surface and in the normal direction of
!!           the maximum slope
!!        k" is the normal to the surface
!!      In order to prevent numerical instability, the implicit scheme has 
!!      been extended to the surface flux regarding to its dependence in 
!!      function of U. The dependence in function of the other components 
!!      introduced by the different rotations is only explicit.
!!      The turbulent fluxes are used to compute the dynamic production of 
!!      TKE. For the last TKE level ( located at PDZZ(:,:,IKB)/2 from the
!!      ground), an harmonic extrapolation from the dynamic production at 
!!      PDZZ(:,:,IKB) is used to avoid an evaluation of the gradient of U
!!      in the surface layer.
!!
!!         In section 6, the same steps are repeated but for the y direction
!!		  and in section 7, a diagnostic computation of the W variance is 
!!      performed.
!!
!!         In section 8, the turbulent fluxes for the scalar variables are 
!!      computed by the same way as the conservative thermodynamical variables
