Chaos Theory Effects Weather Forecast

The man who developed the concept of the "Butterfly Effect" died last week.

Edward Lorenz, 90, discovered that even the smallest discrepancy in data can produce vastly different results when using computer models. This, he explained in a paper published in 1963, is why weather is unpredictable.

Later in 1972, Lorenz gave a presentation titled, "Predictability: Does the Flap of a Butterfly's Wings in Brazil Set Off a Tornado in Texas?"  The "Butterfly Effect" suggests a small flicker of a butterfly's wings can set off a chain of events that can eventually grow into a major disturbance.
