SUMMARY:Characterizing variations in Wisconsin’s extreme weather\, C
 haos & Complex Systems Seminar\, Steve Vavrus\, UW Department of Atmos
 pheric and Oceanic Sciences
DESCRIPTION:Anecdotal evidence suggests an increasing occurrence of ex
 treme weather in recent years\, but a major impediment to identifying 
 and quantifying trends is the absence of a common measuring stick.  Ma
 ny definitions of extreme weather exist\, but they are often haphazard
  and not comparable to one other for quantifying the aggregate behavio
 r of extremes.  To help remedy this problem\, I created a simple\, non
 -parametric index of extreme weather based on the combined percentile 
 rankings of temperature and precipitation (at monthly or longer timesc
 ales).  This integrated index reveals that extreme weather has indeed 
 been unusually pronounced in recent years in Madison and across Wiscon
 sin.  However\, the reasons for the high index values vary considerabl
 y by location.  The temporal and spatial variations of extreme weather
  in Wisconsin and elsewhere are probably a combination of chaotic weat
 her processes and emerging anthropogenic climate change.
