I'm completely new to working with WRF (as of yesterday), and I'm hoping that the LES mode will allow me to run an idealized simulation of marine stratocumulus at very fine (~ 1m!) resolution. I'm also hoping that extraneous computation can be kept to a minimum -- single grid, simple LW radiative parameterization, no SW radiation, fixed SST, periodic lateral boundary conditions, liquid-phase-only cloud physics (Kessler).
The purpose is to try to capture something resembling the fine-scale cloud water density structure of marine stratocumulus clouds forced by radiative cooling at cloud top.
I have already found the "shallow convection" variant of the em_les idealized model, which seems to get me pretty close, but there are a lot of parameters in the namelist.input file whose significance/relevance remains unclear to me despite having read the "best practices" page. I have also already found that WRF crashes if I don't set both a SW and LW radiation scheme; it won't let me set just LW.
If anyone has advice on whether WRF can even do sensible things at this resolution, and if so, what things I should watch out for when setting namelist parameters, I'd greatly appreciate it.
