They are most accurate when forcing is
organized.
Low level upslope, trough/dry line, etc.
Mesoscale circulations like the Denver Cyclone.
As would be expected, local model does well
with terrain forced precipitation: mountain snowfall ( slide
) .
Or, at the other end of the spectrum:
Under
weakly forced "diurnal upslope" model tends to be good for
timing/location of initial convection.
This was not an unexpected result however for the local model used,
which had a grid resolution of 10 km and employed explicit microphysics.
So end up with a few larger sized
storms vs. a greater number of smaller-scale storms.
