A cumulonimbus cloud indicates that moist air in the atmosphere is rising. As the air rises it cools and the water vapor in it condenses, forming clouds. Cloud droplets are too small to fall back to earth, but in the upper part of a cumulonimbus cloud, temperatures are well below freezing. Snow forms in thie part of the storm, melting on its way down to produce rain.
In a strong thunderstorm the updraft, or upward movement of air, is strong enought to keep ice pellets airborne. The pellets circulate in the turbulent updraft, colliding with cloud droplets, which freeze to the surface of the pellets, causing them to grow into hailstones. eventually the hailstones become too heavy for the updraft to keep suspended, or they move to where the updraft is weaker and fall to earth.
Hail can form in thunderstorms associated with other types of clouds, such as supercell clouds or multicell storms. These types of storms have strong updrafts and downdrafts that can support the development of hailstones.
Hail forms when updrafts in thunderstorms carry raindrops into colder regions of the atmosphere. As the raindrops freeze, they grow in size and eventually fall to the ground as hailstones. Hail is typically associated with cumulonimbus clouds, which are large, towering clouds that produce thunderstorms.
Hail requires strong updrafts to keep the hydrometeors suspended to accumulate ice. The only clouds that can normally support these updrafts are cumulus or cumulonimbus (thunderstorm) clouds. Hail requires TWO elements. One is an updraft and the other is that the water inside the cloud reaches the freezing level. This normally occurs only in cumulus or cumulonimbus clouds that extend to fairly high altitudes. Fair weather cumulus, for example, do not obtain the needed height to reach the freezing level.
The hailstones struck the roof loudly during the storm.
A cumulonimbus cloud can produce rain or hail depending on the strength of updrafts within the cloud. If the updrafts are strong enough to carry water droplets high into the cloud where they freeze, hailstones may form. If the updrafts are not as strong, the water droplets will fall as rain.
Cumulonimbus clouds have a large and tall horizontal appearance. They are capable of producing severe weather conditions such as thunderstorms and hailstones.
tornadoes develop from cumulonimbus clouds.
Hailstones start as small pellets of ice in cumulonimbus clouds.They grow larger as they are repeatedly tossed up and down,until they become so heavy that they fall to the ground.
Hail forms in cumulonimbus clouds, which are large, dense, and towering clouds associated with thunderstorms. Within these clouds, strong updrafts carry raindrops high into the atmosphere where they freeze, forming hailstones. These hailstones can grow larger as they are then circulated within the storm cloud before eventually falling to the ground.
Hail A+
Tornadoes form in thunderstorms, which are composed of cumulonimbus clouds. Usually a tornado will form from a wall cloud that develops are the based of the cumulonimbus cloud, and will develop from a funnel cloud that comes out of the wall cloud.
By swirling over by the clouds
Hail occurs in cumulonimbus clouds when ice crystals are repeatedly carried up and down within the storm. As the ice crystals encounter supercooled water droplets, they freeze on contact and grow in size, resulting in hailstones.
Inside a cumulonimbus cloud, there are updrafts that carry water droplets to colder altitudes where they freeze into hailstones. These hailstones can grow as they move up and down in the cloud, eventually becoming heavy enough to fall to the ground as hail. At the same time, the cloud produces rain from the water droplets that don't freeze into hailstones and are too heavy to remain in the cloud.
In the sky especially when a storm coming
