Date: Wed, 27 Oct 2004 07:32:15 -0600 From: Robert Rozumalski Subject: Announcement: National WES case study #21 now available Greetings All, I am pleased to announce new addition to the National Case Study Library: http://strc.comet.ucar.edu/csl National WES case study #21 Title : The Application of Scientific Concepts in Forecasting SuperCell Formation Author : Pablo Santos SIMULATION OBJECTIVES * To review the role of boundaries in tornado genesis through a real event. * To apply concepts related to supercell development including, cross-stream vorticity, streamwise vorticity, hodograph analysis, relative helicity, and Bulk Richardson Number. SIMULATION SUMMARY On March 27, 2003 a low pressure system moving across the NE Gulf of Mexico was accompanied by a strong squall line that swept across South Florida during the afternoon hours. The activity produced widespread severe weather across the WFO Miami County Warning Area with 8 confirmed reports of tornadoes received within a 4 hour period, including an F2 tornado that moved across metropolitan Miami. The event simulation puts emphasis on storm scale boundary interactions and the activity that affected metropolitan area. Case #21 is available on DVD along with a companion simulation guide from the SOO/STRC National Case Study Library: http://strc.comet.ucar.edu/csl Let me know if you have any questions.
