I put together a powerpoint presentation that attempts to explain the origin of the anomalous thermodynamic environment in place during the June 29 – July 01 severe weather outbreak across the Mid-Atlantic/Carolinas. Additionally, the presentation documents rare meteorological phenomena (heat bursts) that occurred over portions of VA, NC and SC in association with the anomalous thermodynamic environment. I’ve attached screen shots of a few slides below. The presentation is roughly 16 MB, and can be downloaded at:
Preliminary Findings Include:
1) The extreme thermodynamic environment in place across the Mid-Atlantic and Carolinas between June 29th and July 1st, 2012 resulted from anomalously steep mid-level lapse rates that originated from the upper Midwest and enhanced low-level moisture that originated from the Gulf of Mexico.
2) The thermodynamic environment over the Mid-Atlantic and Carolinas was almost identical to extreme thermodynamic environments in the Midwest, including the presence of a pronounced elevated mixed layer and a gulf moisture feed.
Any feedback, opposing viewpoints, constructive criticism, debate, etc. would be great!
