cv3p_mixing.F90 @ 3981

Last change on this file since 3981 was 3496, checked in by jyg, 5 years ago

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.

-> no liquid precipitation is ejected
-> 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.
