Changeset 3496 for LMDZ6/trunk/libf/phylmd/cv3p_mixing.F90

Timestamp:

Message:

Implementation of the ejection of liquid precipitation from the adiabatic ascents.
New flags:
+cvflag_prec_eject: logical

n -> old code, y -> new code

+ejectliq: real; possible values 0. & 1.

0. -> no liquid precipitation is ejected
1. -> all liquid precipitation is ejected

+ejectice: real; any value between 0. and 1.

fraction of solid precipitation ejected at each level

Note that the adiabatic ascent mass flux decrease due to precipitation ejection is not taken into account.

Attempts to do it led to water conservation violation.
