rainc is absent in coarse domain only in the nested domain region

Post by rabbanidu93 » Thu Mar 12, 2020 10:07 am

Hello there,
I have used 3 domains. While i visualize the parameter 'rainc' in the coarse/parent domain,
'rainc' is absent in coarse domain only in the nested domain region.
Is this because of my cumulus scheme // cu_physics = 1, 0, 0, // ???
See the picture attached herewith. I've also attached my namelist.input

This setting "cu_physics = 1, 0, 0," turned off cumulus in child domains. I guess you also turn on feedback for this case. Aa a result, the the child domain simulation will feedback to parent domain, which explains why rainc is zero in the parent domain.
