cudt for MSKF (cu_physics = 11)

[Sarath Guttikunda]

cudt (max_dom)

0​

minutes between cumulus physics calls; set to 0 when using all cu_physics except Kain-Fritsch (0 = call every time step)

for cu_physics = 1 (Kain-Fritsch scheme), cudt = 5 is recommended
Does this apply for cu_physics = 11 -- Multi-scale Kain-Fritsch scheme (11)?

or cudt =5 only for option 1 and for everything else is 0?

CUDT can also be applied to other cumulus schemes, including the Multi-scale Kain-Fritsch scheme.

Thank you.
We did a couple of runs with and without cudt (5 and 0) and the difference in precipitation field was small.

 

[Ming Chen]

That is possible.
