Start nested domain after the mother domain

Post by lcana » Wed Feb 04, 2015 3:17 pm

Hi all,

I'm running a high-res simulation with one mother domain and two nested domains (4500-1500-500 m). I'd like to speed my simulation starting the nested domains several hours later. I've read the WRF-EMS docs to find how to do it, but I couldn't find the way. Is it possible? It seems that all the domains must start at the same time.

that is explained inside your wrfems/runs/domain/conf/ems_auto/ems_autorun.conf

Code: Select all

DOMAINS = <domain #:start hr:length>,...,<domain #N:start hr:length>

Code: Select all

#          <start hr after parent> = The number of hours following the start of the
#                                    domain 1 to begin the sub-domain integration.
#                                    Not including this value will cause the EMS to
#                                    begin the nested domain run at the same time as
#                                    as the PARENT domain.

Code: Select all

#        DOMAINS = 2:3    - Start a simulation on domain 2 three hours after the start
#                           of domain 1 and run through the end of the parent domain
#                           simulation.
Hope this helps!
