A storm so fierce, a new term is coined http://apocadocs.com/s.pl?1282481300
A windstorm that swept across Kansas, Missouri, and Illinois on May 8, 2009, was so remarkably fierce that NCAR scientists coined a new term to describe it: super derecho.
A derecho (the Spanish word for "straight") is a long-lived, straight-line windstorm that is associated with a bow echo, or line of severe thunderstorms. The word was first used in the American Meteorological Journal in 1888 by Gustavus Hinrichs, who sought to describe a derecho event in Iowa. The May 8 event, however, was no ordinary derecho. The bow echo produced an eye-like structure similar to tropical cyclones. It gained strength as it moved across Kansas in the early morning hours, spinning off 18 tornadoes and packing wind speeds from 70 to 90 miles per hour when it hit Springfield, Missouri. It plowed a path of destruction through the state about 100 miles wide, crossing the Mississippi River with 90 to 100 mph wind gusts before dissipating at Illinois' eastern border.
