"It's chaos out there," by Nicola Jones. New Scientist, 23 June 2001,page 16.

Chaos theory predicts that small changes in, for example, wind speed, can havedramatic effects on the weather. Chaos theorists examining computer models ofweather prediction found that small changes in the wind had no effect on theweather for most of the globe, but there were a few "hot spots" that weregreatly affected. Weather forecasters already know such hot spots exist, butthis new result might help them locate the hot spots more efficiently.
