Dear regcnet users,
I have run ReGCM-4.1 for six month (March-June)on a domain Meddle East, with EIN15 6-hourly reanalyses and OI_WK SST as
boundary conditions. Although the RegCM4 accurately simulated the spatial distribution in precipitation on all of domain but, it is overestimated over more of domain and the region in comparison with observations.
(figure for 6 month (March-june) total rainfall of ReGCM-4.1 and 4 observations And namelist of model configuration are attached).

Can anybody suggest of tuning any other parameter/variable by which the excessive precipitation over domain may be reduced?
With my best regards,
