I copied it to here at Citizendium as is with the exception that the Wikipedia article title was "Atmospheric dispersion modeling"... and will now delete all of the Wikipedia links and certain sections. I will also be making some wording changes. - Milton Beychok 23:08, 25 January 2008 (CST)

Wanted to clarify one point

Maybe you defined it and I'm not seeing it, or it's one of those case where "it's intuitively obvious", and it actually is because I have an intuition. Confusing enough?

Am I correct in my intuition that a "bent-over" plume is one that moves off the vertical axis of the stack, because its vertical energy is no longer sufficient to overcome horizontal crosswind components? Howard C. Berkowitz 00:05, 29 December 2008 (UTC)

Yep, your intuition is correct. I did not define it because I thought that the diagram I provided was adequate to define the plume shape. Do you think a textual description is also needed? Would it be better if I simply expanded ... he proposed for bent-over, hot buoyant plumes to ... he proposed for bent-over, hot buoyant plumes (as depicted in the plume diagram) ? Milton Beychok 01:02, 29 December 2008 (UTC)
You could either do that, or just describe it directly in text -- something along the lines of when crosswinds start to bend it off vertical, or something more in vectors. "Howard C. Berkowitz 01:16, 29 December 2008 (UTC)
I implemented your suggestion in the simple way that I proposed just above because I think a picture is always more effective than words to non-experts. Thanks again, Milton Beychok 03:42, 29 December 2008 (UTC)
