Influence of Clouds on Boundary Layer (preliminary)

This page describes some preliminary results on the role of clouds in the boundary layer, using the aircraft profiles.
The inversion base deepends more with clouds present than jet height, which explains why you must scale temperature and wind profiles with different height scales.

Most of the plots in the table below show the distribution of the variable under clear and cloudy conditions.
The mean value is indicated.
Cloudy = liquid water content > .02 in the profile.
Keep in mind sampling problems associated with profiles being taken near capes.

Cloudy

Clear

Inversion base deeper
Jet height a little deeper
Larger difference in inversion base height than jet height
Offshore flow Downstream from capes
Bouyancy flux > 0 Buoyancy flux < 0
More onshore flow More offshore flow

No difference with...

Inversion strength
