Confusion about PBL

Postby Jennylucky » Mon Jun 13, 2016 2:58 am

Hello everyone,
I'm confused with the surface layer physics and planetary boundary physics in WRF model recently.
First, what's the lower bound of PBL in model ? the top of surface layer or ground ?
Second, what exactly the difference or relation between the surface layer and PBL scheme ? Does they transport the flux with different way ? For example, sfclay scheme computed the flux based on Monin-Obukhov similarity , but PBL shcme based on K-theory or TKE closure method and so on. I don't know whether this understanding is right , any help would be greatly appreciated.
Thanks very much !
