“The fast-moving squall of severe thunderstorms that ripped through the Chicago area Monday is called a derecho,” Tom Skilling writes this morning.
“The high speed, bow-shaped line of storms left an astounding 1,400-mile trail of damage across sections of 17 states in 30 hours.
“Long-lived, especially fast-moving, squall lines have been dubbed ‘derechoes’ since the term was first proposed in 188[8] in the American Meteorological Journal by Gustavas Hinrich[s], a Danish born University of Iowa scientist.”
