Hi all.
I have been able to successfully run WRF (4.1.1) on the Amazon cloud using GFS input data on a region covering NW South America and a nest zoomed on on a mountainous part of Colombia. It ran fine using the "tropical" physics suite, however... when I change a few physics options, it always crashes in the land surface scheme.
See attached rsl and namelist. I copied a namelist that works on the same input files, and only changed these options, which crashes it:
mp_physics = -1, -1, 8,
cu_physics = 3, 3, 0,
lightning_option = 0, 0, 3,
(27-9-3 km domain grid spacing)
I wanted to experiment because the convective rainfall seems over-predicted near the mountains. On satellite there is no sign of convective clouds. With nwp_diagnostics =1 it shows even widespread signal in HAIL_MAX2D which is not simply cumulus to me.
I also got some meridional patterns in the cumulus rain which seem artifacts, maybe from interpolation of land surface properties?
Your suggestions are welcome.
best regards,
Oscar
