SUMMARY:Variability\, uncertainty\, and vulnerability in our chaotic c
 limate \, Chaos & Complex Systems Seminar\, John Young\, UW Department
  of Atmospheric and Oceanic Sciences
DESCRIPTION:Climate and weather are part of a chaotic continuum which 
 impact our world through variability\, predictive and statistical unce
 rtainty\, and damaging extremes. In this talk I will illustrate these 
 issues with examples from observed atmospheric temperature and precipi
 tation patterns and time behavior.<br>
\n<br>
\nWeather chaos naturall
 y extends to slow variations and often power-law spectra. The probabil
 ity distributions of temperature differ strongly from those for precip
 itation\, which yield power law distributions at the extreme range. Im
 pacts often result from extreme states which exceed threshold values. 
 Since extremes are typically estimated with large uncertainty\, ecolog
 ical impacts are similarly estimated for a finite range of probability
 . An example of a physical constraint on extreme precipitation will be
  given: the "1\,000 year flooding rain".
