<p>What is the range of horizontal pressure gradients typically caused by the differential heating of land and water under sea breeze conditions?</p>

In my notes I have this modeled as a density current on at a constant pressure.  When I get some free time I'll look deeper at it.  Perhaps even model it.

@aretxabaleta's answer is a good start, but it indicates that the question could have some more detail: Are you interested in the extreme ranges, or just common behaviours? And for just a single site, or for any place/terrain type on earth?
