Changeset 2761 for LMDZ5

Timestamp:

Jan 11, 2017, 12:39:50 PM (8 years ago)

Author:

Message:

Two options introduced concerning deep convection
and wakes:

+ deep convection is allowed only when top
temperature is lower than t_top_max.
(Default: t_top_max=1000.).
+ wake number per unit area may now be
different over ocean and over land:
wdens_ref_o and wdens_ref_l.
(Default is:wdens_ref_o=8.e-12,
wdens_ref_l=8.e-12)
