Subject: Announcement: New WES Data set - Atypical Tornado Producing Thunderstorms



Greetings All,

I am pleased to announce new addition to the National
Case Study Library:

   http://strc.comet.ucar.edu/csl


National WES data set #4

Title       : Atypical Tornado Producing Thunderstorms in Oklahoma
Authors     : David Andra and Bernard Meisner


SIMULATION OVERVIEW

  This case does not include a companion study guide; however,
  one could still use this data set to create a training session 
  with little effort.
   
  Training materials for this case include a damage survey, Storm Data
  information, a Powerpoint presentation, and a case summary paper 
  entitled "Radar signatures Associated with Atypical Tornado-Producing
  Thunderstorms in Oklahoma".
  

EVENT SUMMARY

  During the late night and early morning hours of 11 April 2001, 
  a quasi-linear complex of severe thunderstorms, with several 
  embedded mesocyclones, moved across portions of central, south
  central and southeast Oklahoma. This complex of severe thunder-
  storms produced several tornadoes and other non-tornadic wind 
  damage in portions of Atoka, Coal, Johnston, Love, Marshall, and 
  Pottawatomie Counties between approximately 1 AM and 6 AM CDT 
  (0700-1100 UTC). Many reports of damage, along with two injuries 
  and one death related to the storms, were received by the National 
  Weather Service Forecast Office (NWSFO) in Norman, OK, between 6
  AM and 8 AM CDT (1100-1300 UTC) 11 April. Based on these reports, 
  the decision to conduct a damage survey of the affected areas was 
  made. NWSFO Norman and National Severe Storms Laboratory (NSSL) 
  personnel conducted ground and aerial damage surveys of the storm-
  affected areas from 11-17 April 2001. The survey revealed the paths 
  of five tornadoes, and other instances of wind damage.


Data set #4 is available on DVD from the "Data-only Cases" section
