Roiling??

You have copied a passage from the source in your second para. The copy includes an apparent misprint in the original. I think the word "roiling" does not exist, and that "boiling" is meant. Anyway, I demote the page to C class; virtually all the first two paras are verbatim from the source quoted. Macdonald-ross (talk) 16:54, 13 August 2012 (UTC)[reply]

"Roiling" is not a misprint. At m-w.com it is defined as "moving turbulently," which makes it a much better choice here than "boiling."--RichardMathews (talk) 23:18, 14 August 2012 (UTC)[reply]
