National Geographic : 1987 Jan
Smashing property and prices, a July 1984 hailstormreduced the value of a used Porsche 944 on a Munich, West Germany, car lot from $15,000 to $4,000 (below). In Texas a baseball-size hailstoneput a major-leaguedent in a car hood (above), striking at perhaps 90 miles an hour. Falloutfrom violent weather systems, hailstonesgrow onionlike layers as they pass through clouds of supercooled waterdroplets. (Frozensingle raindropsare called sleet, a close cousin.) Economic damagefrom hail in the U. S., primarily through destructionof crops, exceeds that caused by tornadoes.
