It's been reported before, and is being looked into. The intensity is a % in the panel and between 0 and 1 from an expression.
I think a UDF (DEFINE_PROFILE) will work otherwise it's more usual to set k and e/w depending on the turbulence model. There are papers with the atmospheric boundary layer profiles, we tend to use the one by Hoxey (I think - I've lost the reference).
