[Wrf-users] wrf parameterizations

Dear users,

I'm trying to find a better configuration of wrf parameterizations to 
describe the atmospheric conditions concerned to instability when 
lightning happens. I've set 2 domains, the coarse 30 km grid and the 
nest 10 km grid. I'm not working with high resolution because the 
integration time is very important to my purposes, so I focus my 
analysis on the nest outputs. Firstly I tested 3 different sets of 
cumulus and microphysics options: 1) Kain-Fritsch and WSM3; 2) 
Betts-Miller-Janjic and Ferrier; 3) Grell-Devenyi and Lin. The best 
results I've found with the first set. Physically I'm trying to explain 
this but it's difficult. I would like to understand a little more the 
diferrences among these parameterizations. Can anyone help me?

Thanks in advance.
Best regards,
