!!**** * - compute the explicit microphysical sources
!!
!! PURPOSE
!! -------
!! The purpose of this routine is to compute the slow microphysical sources
!! which can be computed explicitly
!!
!!
!!** METHOD
!! ------
!! The autoconversion computation follows Kessler (1969).
!! The sedimentation rate is computed with a time spliting technique and
!! an upstream scheme, written as a difference of non-advective fluxes. This
!! source term is added to the future instant ( split-implicit process ).
!! The others microphysical processes are evaluated at the central instant
!! (split-explicit process ): autoconversion, accretion and rain evaporation.
!! These last 3 terms are bounded in order not to create negative values
!! for the water species at the future instant.
!!
!! EXTERNAL

!! None
