Hello to everyone,

I'm trying to obtain wind speed and direction in a city located near a coast in Colombia's Pacific Zone, also the city (Santiago de Cali) is located at the bottom of Los Andes Mountain so it's terrain is very complex. Wind direction results are awful. I tried several configurations but still can't get good results. I used 2 nested domains, 3 nested domains, ERA5 data, GFS data, tried to change the grid sizes for the domains.

Still don't know what to do.

Thanks in advance for your help.
