2-way nesting wrf-les (framework)

[Palma]

Dear all,

I am Massimiliano Palma and I am an Italian PhD student in “Earth Science and Fluid Mechanics”.

I am approaching for the first time to WRF model. I am interested in “2-way nesting in the wrf-les”. Precisely I am interested in “how it was developed” (about the framework) and not in “how to run it”. So I am writing to ask you if you could help me and if you could tell me some information about.

Precisely I would be grateful if you could explain to me the numerical technique occured in the 2-way nesting and/or if you could indicate to me in which part of the code it is implemented (if some subroutine exist..)

Moreover I read that one problem arise from the choice of the SFS model. Is the “Nonlinear Backscatter with Anisotropy (NBA) SFS model” the one and only best choice in order to develop a 2-way nesting?

I would be really grateful if you could support me
Best regards
Massimiliano
