I think it is not correct to define the buoyancy flux as in the currently present form:
I would like to discuss the following points:
- This equation is an approximation for the flux that involves Reynolds averaging and some neglections. It is not a definition.
- This approximation is not accurate (see "An Introduction to Boundary Layer Meteorology" by Roland B. Stull, 1988).
- The actual temperature should be replaced by potential temperature.
- Hence, better use the following formulation:
The above formulation is the "correct" result from the definition of virtual potential temperature, splitting into mean and turbulent state and subsequent Reynolds averaging - but the triple correlation
- An important part of this article is a copy-paste from the book "Fundamentals of atmospheric modeling" by Mark Z. Jacobson without reference.

I'm preparing an article on Monin-Obukhov similarity theory as part of an UCLA class project (The Atmospheric Boundary Layer ), which will probably be more comprehensive than this one. I have gathered references and will draft in my sandbox. Let me know if you have any comments or feedback. Thank you. Geoalchimista (talk) 20:30, 29 April 2014 (UTC)
I suggest this page is merged with Monin-Obukhov similarity theory; both are marked as being too technical, and a page on the Obukhov length is inevitably going to be incomprehensible without the context of the similarity theory that it is applied to. When I have time I could help trying to improve a merged page as I taught masters-level Boundary-Layer Meteorology for a number of years. This would also resolve the question of whether to call the page the Obukhov or Monin-Obukhov length (is is more common to call it the former). Rjhogan (talk) 09:16, 23 October 2017 (UTC)
The article now only seems to discuss the Monin-Obukhov length in the atmosphere (with the formula for specific humidity). Should it not also discuss the Monin-Obukhov length in the ocean upper layer (for instance such as described in chapter 14 of Introduction to Geophysical fluid dynamics by Cushman-Roisin, 2011)?
