It certainly does. Most introductory meteorology texts will have a chapter
on the boundary layer and its height that should answer your questions.
One point to note: during summer, over land, it is quite easy for the
boundary layer to be mixed as high as 3km, even a bit higher. Smoke from
forest fires can mix up a lot during the day, then get trapped below 500m
at night if the fire is not too large.
Alister.
