Hi,
I am running WRF (v3.9.1) in cycling mode (every 6 hour) using WRFDA on a previous 6h WRF forecast as background. I normally use adaptive time stepping, to save on simulation time. If I run WRF in cold mode, it works just fine. But if I run WRF every six hour, using previous 6h forecast as background and with use_adaptive_time_step=.true. in the WRF namelist, the WRF run starts but stops immediately saying WRF successfully ended, but without having done any time integration at all. If, leaving everything else the same, I set use_adaptive_time_step=.false. , then the run proceeds and does its 60h of integration. I cannot figure out why? Did anyone experience this before?
Any help would be greatly appreciated!
