	Hail - Wikipedia, the free encyclopedia
		Hail is a type of graupel (a form of precipitation) composed of spears or irregular lumps of ice.
		Rarely, massive hailstones have been known to cause concussions or fatal head trauma.
		The ruler shows the size of this hailstone as approximately 6 cm, almost the size of a tennis ball.

	Hail Formation, Alaska Science Forum (Site not responding. Last check: 2007-10-09)
		Important to the buildup of hailstones is the existence in thunderhead clouds of supercooled water: water that remains in liquid form well below normal freezing temperature.
		In the north, large hailstones are rare because the lack of strong ground surface heating does not favor the buildup of the gigantic thunderstorms common in some temperate climates.
		Hailstones there were about the size of large grapefruit with an average diameter of 5 1/2 inches.

		The hailstone was recovered in Aurora on June 22.
		The old record for the largest hailstone had a diameter of 5.7 (14.5 centimeters) inches, a circumference of 17.5 inches (44.5 centimeters), and was found in Coffeyville, Kansas, on September 3, 1970.
		The hailstone lost nearly half of its mass upon landing on the rain gutter of a house.

		The damage caused by hailstones is proportional to their kinetic energy when they hit the ground.

		A typical hailstone has a radius around 1 cm, but during a 1970 thunderstorm in Coffeyville, Kansas, the largest hailstone ever recorded had a radius around 7 cm.

	The World's Heaviest, Fastest and Most Beloved Hailstone.
		But since hailstones challenging the world's record need to be sent to the Boulder, Colorado laboratory for verification, there's no telling how much weight, diameter or circumference was lost in transit.
		The intense desire to hold any hailstone record plus the quantum advances in modern radar detection have led some communities in the Great Plains to ask the help of local law enforcement personnel (formerly known as police or state troopers) in measuring the speed of descending hailstones.
		In the states that comprise the Great Plains, hailstone spotting is one of the fastest growing activities for "young and old alike." Immediately after a hailstorm, helmeted aficionados can be seen running outside - even before the "all clear" warning is announced - hoping to find a contender for the world record.

	Cliff Pickover's Patterns in the Mysterious Hailstone (3n+1) Numbers
		For example, the hailstone sequence for 3 is: H(3) = { 3, 10, 5, 16, 8, 4, 2, 1, 4,...}.
		For the hailstones, we are often multiplying by 3 and then dividing by 2.
		A number of researchers have noted that the hailstone sequence gives rise to a mixture of regularity and disorder: it is definitely not random, but the pattern resists interpretation.

	Fluid Friction
		Contributing to the danger of large hailstones is the fact that they fall faster than small ones.
		That is, the terminal velocity increases with the size of the hailstone.
		Assuming the hailstones to be spherical and using a drag coefficient of C = 0.5 gives the following :

	Hail
		NCAR scientist Nancy Knight holds a hailstone that fell in Coffeyville, Kansas, in 1970.
		When a hailstone falls through air with a smaller amount of liquid, the liquid freezes on contact with the hailstone, forming small air bubbles in the opaque layers.
		While hailstones have been found weighing as much as 0.75 kilograms (1.67 pounds), even much smaller hail can destroy crops, slicing corn and other plants to ribbons in a matter of minutes.

	Speed of a Falling Hailstone
		A hailstone falls to the earth when it becomes too heavy for an updraft to keep it up.
		Due to the fact that hailstone do not come in one size all hailstones do not fall at the same speed.
		A third smaller factor is the shape of the hailstone because different shapes create different amounts of air resistance.

	Impact Damage From Hail Storms
		Accounting for the air resistance force as the hailstone falls is necessary, but the air resistance does not necessarily remain constant.
		However the air resistance can be calculated at an instant based on the velocity of the hailstone relative to the air, a drag coefficient, the density of the air through which it moves, and the cross-sectional area of the hailstone.
		Since the density of the hailstone is about one-thousand times greater than that of the air, the buoyant force is very small compared to the weight of the hailstone.

		When considering storm reports from 1999, it was noticed that 1,618 1.75-inch hailstone entries were added to the database, as compared to 256 1.25-inch hailstone entries.
		However, there have been no studies done to correlate damage to the size of hailstones, and then apply this to better lead times on warnings, but such a topic is worthy of research.
		An additional point of research is the potential of hailstones to be severe based on the vertical height of the updraft and the position of the wet-bulb zero layer.

	Hail
		A piece of hail is called a "hailstone." Hailstones start out as really tiny balls of ice in a thunderstorm.

	More on hail
		A hailstone often consists of several concentric layers, which are either clear or milky.
		Sometimes a hailstone will shed water, even when it is still above the freezing level, because the latent heat released when water is frozen makes the hailstone warmer than the environment.
		The presence of multiple layers indicates that the hailstone was lifted several times by the storm's updrafts, however this 'recycling' appears to be not necessary for the formation of large hailstones.
