How to run WRF-LES

[Mob]

Hello. I am pretty new to the WRF and want to know how to run a WRF-LES simulation. Does one have to run ndown.exe for LES with pbl scheme off? Also, is there any step by step guide that I can follow to run LES?

WRF provides a capability for ideal LES simulation. Please take a look at the WRF/test/em_les/README.les to get some idea how it works.
Note that real-data LES simulation could be more complicated.

Hi. I am trying to compile the em_les and when I run ./compile em_les only the executables wrf.exe and real.exe are created. Does anyone know why this could happen?

Did you follow the steps below ( in top WRF directory):
./clean -a
./configure (then choose the option you want)
./compile em_les

You should have ideal.exe and wrf.exe produced.

Thanks for answering
I follow exactly those steps and it only generates the ideal.exe and the wrf.exe. That is my question, if when compiling the em_less I should only wait for these two executables

 

[Ming Chen]

That is right.
