HUNTSVILLE, Ala. (October 18, 2011) — The University of Alabama in Huntsville’s Earth System Science Center and its Atmospheric Science Department have a major presence at the National Weather Association’s annual meeting this week in Birmingham. Students, faculty and research staff are scheduled to make ten talks during the four-day meeting, with an additional 13 poster presentations. The center’s severe weather research group also had a presence at the NWA’s ‘Weatherfest’ on Sunday at the McWane Science Center. About 400 people toured the Mobile Integrated Profiling System or learned about the Mobile Meteorological Measurements Vehicle. Presentations in which UAH students, faculty or staff were involved included: The Rare Synoptic and Mesoscale Setup Leading to the 27 Apr 2011 Tornado Outbreak, Dr. Timothy Coleman, UAH.
