!!**** *ANEL_BALANCE_n* - routine to apply an anelastic correction
!!
!!
!! PURPOSE
!! -------
! The purpose of this routine is to fulfill the anelastic balance
! in case of non-vanishing orography
!
!
!
!!** METHOD
!! ------
!! The coefficients for the flat operator are first computed. Then the
!! pressure equation is solved and the pressure gradient is added to the wind
!! components in order to render this wind field non-divergent.
!!
!! EXTERNAL
!! --------
!! TRID : to compute coefficients for the flat operator
!! PRESSURE : to solve the pressure equation and add the pressure term to
!! wind
!! MXM,MYM,MZM : to average a field at mass point in the x,y,z directions
!!
