Figure 3 Images of hailstones made of PVA with a diameter of … Terminal velocity of hail, or the speed at which hail is falling when it strikes the ground, varies. It is estimated that a hailstone of 1 cm (0.39 in) in diameter falls at a rate of 9 m/s (20 mph), while stones the size of 8 cm (3.1 in) in diameter fall at a rate of 48 m/s (110 mph). See more Hail is a form of solid precipitation. It is distinct from ice pellets (American English "sleet"), though the two are often confused. It consists of balls or irregular lumps of ice, each of which is called a hailstone. Ice pellets … See more Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid-water content, great vertical extent, large water … See more The size of hailstones is best determined by measuring their diameter with a ruler. In the absence of a ruler, hailstone size is often visually estimated by comparing its size to that of known objects, such as coins. Using the objects such as hen's eggs, peas, and … See more Narrow zones where hail accumulates on the ground in association with thunderstorm activity are known as hail streaks or hail swaths, which can be detectable by satellite after the storms pass by. Hailstorms normally last from a few minutes up to … See more Any thunderstorm which produces hail that reaches the ground is known as a hailstorm. An ice crystal with a diameter of >5 mm (0.20 in) is considered a hailstone. Hailstones can grow to 15 cm (6 in) and weigh more than 0.5 kg (1.1 lb). Unlike ice pellets, … See more Hail occurs most frequently within continental interiors at mid-latitudes and is less common in the tropics, despite a much higher frequency of thunderstorms than in the mid-latitudes. Hail is also much more common along mountain ranges because mountains … See more Hail can cause serious damage, notably to automobiles, aircraft, skylights, glass-roofed structures, livestock, and most commonly, See more
