cv3p2_closure.F90 @ 2398

Last change on this file since 2398 was 2398, checked in by jyg, 9 years ago

Introduction of two new flags (ok_conv_stop
[Def=F], ok_intermittent [Def=F]) and one new
parameter (tau_stop [Def=15000]) in
conv_param.data:

. ok_conv_stop=T => convective mass fluxes are

set to zero if there is no trigger for a time
lapse longer than tau_stop.

. ok_intermittent=T => intermittent convection is

represented; the change concerns the upper
bound on the cloud base mass flux in
cv3p2_closure.F90.

The upper bound on Alp in physiq.F90 should

also be changed: this is still to be done.
