Freezing Rain Next Topic: Graupel

Freezing rain is a condition where precipitation which has fallen in the form of water droplets reaches temperatures which are below freezing and freezes upon coming into contact with surface objects. The result of this precipitation is a glaze of ice which can be damaging to plants and man-made structures. A severe onset of freezing rain which results in a very thick glaze of ice is known as an ice storm.

Hail Next Topic: Hole Punch Clouds

Hail is a form of precipitation which is recognized by large solid balls or clumps of ice. Hail is created by thunderstorm clouds with strong updrafts of wind. As the hailstones remain in the updraft, ice is deposited onto them until their weight becomes heavy enough for them to fall to the earth's surface.

Hail storms can cause significant damage to crops, aircrafts, and man-made structures, despite the fact that the duration is usually less than ten minutes.
