Cloud seeding in the United Arab Emirates is a weather modification technique used by the government to address water challenges in the country. Cloud seeding is also referred to as man made precipitation and artificial rain making. [61] The United Arab Emirates is one of the first countries in the Persian Gulf region to use cloud seeding ...
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.
Furthermore, the hailstone's speed depends on its position in the cloud's updraft and its mass. This determines the varying thicknesses of the layers of the hailstone. The accretion rate of supercooled water droplets onto the hailstone depends on the relative velocities between these water droplets and the hailstone itself.
What makes a hailstone grow? Big rotating supercell thunderstorms produce the lion’s share of large hail, Gensini said. Supercells are a type of large thunderstorm with a rotating vortex of air ...
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.
Hail can melt quickly before a measurement can be taken. Spotter reports can be estimated. Although oblong conglomerations of hailstones can have a large diameter, they may weigh less than other ...
A large hailstone, about 6 cm (2.4 in) in diameter. Hail forms in storm clouds when supercooled water droplets freeze on contact with condensation nuclei, such as dust or dirt. The storm's updraft blows the hailstones to the upper part of the cloud. The updraft dissipates and the hailstones fall down, back into the updraft, and are lifted up again.
Ice particles can have a significant effect on cloud dynamics. They are known to be important in the processes by which clouds can become electrified, which causes lightning. They are also known to be able to form the seeds for rain droplets. It has become clear that the concentration of ice nucleating particles in shallow clouds is a key ...
