r625 r667 4 4 ! Current revisions: 5 5 !  6 ! 6 ! When advection is computed with wsscheme, turbulent fluxes are already 7 ! computed in the respective advection routines and buffered in arrays 8 ! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the 9 ! numerics and to avoid unphysical kinks near the surface. 10 ! So some if requests has to be done to dicern between fluxes from wsscheme 11 ! other advection schemes. 12 ! Furthermore the computation of z_i is only done if the heat flux exceeds a 13 ! minimum value. This affects only simulations of a neutral boundary layer and 14 ! is due to reasons of computations in the advection scheme. 15 ! 7 16 ! 8 17 !
