Case Studies

Another facet of my research on Cool-Season High Wind Events is investigating selected cases. Below is a preliminary list of cases with some loops of interesting features associated with each case:

17 February 2006
1 December 2006
1 December 2004

    17 February 2006: The first Northeast report occurred 0900 UTC 17 Feb 2006. A hybrid high wind event that accumulated the most high wind reports (267 total; 242 gradient and 25 thunderstorm reports) in the Northeast domain

    1 December 2006: The first Northeast report occurred 1600 UTC 1 Dec 2006. Another high impact hybrid event with similar characteristics as the 17 February 2006 case, however this case produced more thunderstorm wind reports (242 total; 117 gradient and 129 thunderstorm reports)
