  !======================================================================

  ! Purpose:
  !    Calcul la difference d'enthalpie et de masse d'eau entre 2 appels,
  !    et calcul le flux de chaleur et le flux d'eau necessaire a ces
  !    changements. Ces valeurs sont moyennees sur la surface de tout
  !    le globe et sont exprime en W/2 et kg/s/m2
  !    Outil pour diagnostiquer la conservation de l'energie
  !    et de la masse dans la dynamique.


  !======================================================================
  ! Arguments:
  ! tit-----imput-A15- Comment added in PRINT (CHARACTER*15)
  ! iprt----input-I-  PRINT level ( <=1 : no PRINT)
  ! idiag---input-I- indice dans lequel sera range les nouveaux
  !              bilans d' entalpie et de masse
  ! idiag2--input-I-les nouveaux bilans d'entalpie et de masse
  !             sont compare au bilan de d'enthalpie de masse de
  !             l'indice numero idiag2
  !             Cas parriculier : si idiag2=0, pas de comparaison, on
  !             sort directement les bilans d'enthalpie et de masse
  ! dtime----input-R- time step (s)
  ! uconv, vconv-input-R- vents covariants (m/s)
  ! ps-------input-R- Surface pressure (Pa)
  ! p--------input-R- pressure at the interfaces

  ! q--------input-R- vapeur d'eau (kg/kg)
  ! ql-------input-R- liquid watter (kg/kg)
  ! aire-----input-R- mesh surafce (m2)

  ! the following total value are computed by UNIT of earth surface

  ! d_h_vcol--output-R- Heat flux (W/m2) define as the Enthalpy
  !        change (J/m2) during one time step (dtime) for the whole
  !        atmosphere (air, watter vapour, liquid and solid)
  ! d_qt------output-R- total water mass flux (kg/m2/s) defined as the
  !       total watter (kg/m2) change during one time step (dtime),
  ! d_qw------output-R- same, for the watter vapour only (kg/m2/s)
  ! d_ql------output-R- same, for the liquid watter only (kg/m2/s)
  ! d_ec------output-R- Cinetic Energy Budget (W/m2) for vertical air column
