Hail is a form of solid precipitation. [1] It is distinct from ice pellets (American English "sleet"), though the two are often confused. [2] It consists of balls or irregular lumps of ice, each of which is called a hailstone. [3] Ice pellets generally fall in cold weather, while hail growth is greatly inhibited during low surface temperatures.
As the hailstone ascends it passes into areas of the cloud where the concentration of humidity and supercooled water droplets varies. The hailstone's growth rate changes depending on the variation in humidity and supercooled water droplets that it encounters. The accretion rate of these water droplets is another factor in the hailstone's growth.
Video footage of the rockslide shows the rocks tumbling down along with parts of mountain onto the road in a cloud of dust. The video was recorded by Sierra Wright, who told Storyful she made the ...
A capping inversion occurs when there is a boundary layer with a normal temperature profile (warm air rising into cooler air) and the layer above that is an inversion layer (cooler air below warm air). Cloud formation from the lower layer is "capped" by the inversion layer.
One hailstone that fell in Texas on April 28, 2021, set a new state record at 6.4 inches in diameter, and Colorado set its state record with a 5.25-inch stone that fell on Aug. 8, 2023.
A hailstone grows larger when other drops freeze onto its surface while it is inside an updraft, creating growth layers and the knobby appearance that big stones get as they spin and tumble in the ...
Clouds form as relatively warmer air, carrying moisture, rises within cooler air. The moist air rises, and, as it does so, it cools and some of the water vapor in that rising air condenses . [ 10 ] When the moisture condenses, it releases energy known as latent heat of condensation, which allows the rising packet of air to cool less than the ...
Research suggests climate change will make hailstones larger. Already, hail has caused higher damage costs in the U.S. this year than hurricanes and floods put together.
