The hail has its origin in thunder storm in our atmosphere - cumulonimbus clouds and it reaches the ground as a hailstorm, producing hailstones of varying diameter from 5 millimeters (0.20 in) to 15 centimeters (6 in) and weigh more than 0.5 kilograms (1.1 lb). When the atmospheric condition favors strong, upward motion of air or updraft of air in the parent thunderstorm clouds with high water content, great vertical extent and freezing point - below freezing 0 °C (32 °F) at lower altitude, as in the formation of twisters or tornadoes that require strong updrafts, it will be conducive to the formation of hailstorms.

hail can exhibit a typical or characteristic green coloration. This is true of many case..................
You will be surprised to know the world's worst hailstorm disaster on account of bizarre and extreme weather anomalies over the present state of Uttar Pradesh occurred in April of 1888 at Moradabad during the British Raj under the English Crown. The Guinness World Records list the Moradabad hailstorm as the world's worst hailstorm disaster in history. The hailstorm left behind a trail of immense destruction and disaster, extensive loss of livestock - more than 1600, badly damaged homes, huts, etc besides worst human tragedy - 246 people were killed and scores of people severely injured. Sixteen others died in the nearby Bareilly district.
The Nature's fury was hell-bent on Moradabad, the hailstones started falling from the sky on Tuesday night and covered the entire villages under the snow-like blanket. The whole area was literally battered by the high velocity hailstones as if the hell-gate in the upper world was wide open to relieve them. People reported hailstones varying in size from pigeon’s eggs to the size of oranges and the big ones falling at speeds exceeding 100 mph. You can very well imagine what kind of impact such high velocity falling solid objects will cause. There was an accumulation hail up to two feet, once the storm was over.
