As a consequence of this, default of [../../app/inipar#bc_s_t bc_s_t] changed to 'initial_gradient', and new value 'neumann' can be prescribed if using top_scalarflux.

 If it is set to .F. (default), the large scale subsidence velocity w_subs is used to advect the prognostic variables (subroutine  {{{subsidence}}}).

-Two-moment cloud microphysics improved. As a new default, two-moment cloud microphysics are called just once before the time step (and not before every sub-time step). Not affecting the results substantial, these changes increases the computational feasibility of the two-moment cloud microphysics scheme. Note that the computation of microphysics before every sub-time step is still possible by setting the new parameter [../../app/inipar#call_microphysics_at_all_substeps call_microphysics_at_all_substeps] = .T.. A vector-type CPU optimized version of the two-moment cloud physics was added as well. Moreover, the individual subroutines of microphyiscs were reviewd to increase their computational performance. The computation of turbulent surface fluxes of rain water content (qr) and rain drop concentration (nr) were added (bugfix). The default of [../../app/inipar#drizzle drizzle] has been set to .T., since analysis showed that its computational needs are marginal. In prognostic_equations, w_subs is allocated only if it is not allocated before (bugfix).
