RADAR DETECTS A HAILSTONE
When it was discovered that radar could locate rainstorms, meteorologists quickly moved the device into the arsenal of weather observing equipment, and scientists began to look for other applications. Early in the game attempts were made to devise techniques for observing a form of precipitation which causes damage in the millions of dollars every year --hail.
Almost everyone, at one time or another, has seen hailstones. They are large particles of ice which fall out of some thunderstorms.
