+>> UPDATE ON PARAMETERS TO SET TO USE THE THERMALS MODEL 
+********************************************************
+
+>> IN CALLPHYS.DEF <<
+---------------------
+
+- calltherm = .true.       > activates the thermals
+- callrichsl = .true.      > activate the Richardson Monin Obukhov surface layer
+with subgrid gustiness, and the yamada4 diffusion model from earth (corrected version of vdif_kc)
+- leave calladj = .true.   > so that the convective adjustment may work ABOVE the PBL.
+
+>> IN RUN.DEF <<
+----------------
+
+- 96 physicial timesteps per day (the internal sub-timestep of thermals will adapt
+so that it costs only 10% more CPU time to go from "48pdt+thermals" to "96pdt+thermals".)
+> this has to be respected because of a coupling between the radiative transfer and thermals
+> if you really wish to run with 48 pdt/day, you may want to deactive the thermals...
+
+>> USEFULL DIAGNOSTICS <<
+-------------------------
+
+- activating the thermals will automatically add 3 2D-outputs to diagfi.nc files:
+> zmax_th : interpolated boundary layer height (m)
+> hfmax_th : maximum vertical eddy heat flux reached in thermals (K.m/s)
+> wstar : free convection velocity reached in thermals (m/s)
+
+A rule of thumb for determining the mean velocities in subgrid-scale structures is:
+
+Mean updraft velocity : ~ wstar
+Maximum updraft velocity : ~ 2 or 3.*wstar
+Mean downdraft velocity : ~ 0.66*wstar
+Maximum absolute value of downdraft velocity : ~ 2.*wstar
+
+>> AT COMPILATION TIME <<
+-------------------------
+
+- +1 vertical level during the compilation, and then using the updated z2sig.def
+
+>> UPDATED Z2SIG.DEF <<
+-----------------------
+
+- one level has been added in the PBL, so that to reach 150km you have to compile with
+33 vertical levels instead of 32.
