When hail is formed, it is not instanteous nor fall immediately. Storms have a peculiarosity of up and down flowing winds. When a droplet of water in the clouds began to fall, the very low temperatures present cause the droplet so form a skin of ice. This droplet then goes thru a series of upward and downward journeys until enough ice is formed to the weight that it can escape the forming arena and thus falls to earth. It is well known, for instance, within each piece of hail, no matter the size, the original droplet still exists.

The best answer is that it depends on the air temperature in the upper levels of the atmosphere, as well as if there is a strong enough updraft in that particular thunderstorm to support the formation of hail. During a thunderstorm, rain drops are often times carried back up into the thunderstorm cloud and it freezes. This pattern happens over and over again until the updraft can no longer support the frozen ice. This ice then falls to the earth as "hail." If it is too warm in the lower levels of the atmosphere, then it can melt back to water before even reaching the ground.

Cumulonimbus clouds are very 'tall' clouds - with very cold temperatures at the top. Air currents within the clouds allow raindrops to be blown upwards towards the colder part of the cloud - which makes moisture freeze to the surface of the raindrop. The hail stays within the cloud until they get too big for the air currents to keep them there.

What is a name that form hail besides cumulonimbus clouds?

Cumulonimbus clouds are the only clouds that can form hail. No other cloud is capable of doing so.


How is a cumulonimbus cloud different from other clouds?

Cumulonimbus is the largest type of cloud. It is the only cloud that is tall enough to occupy low, medium and high heights. It is also the only (weather related) cloud that can form hail and lightning. Lightning can also be created in volcanic ash clouds, but they are not a weather related cloud.


What kind of clouds were out yesterday?

status clouds or cumulonimbus clouds


What type of cloud does a hailstone come from?

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.


What cloud does hail fall from?

Hail forms in thunderstorms (cumulonimbus clouds) when large updrafts carry water droplets high into the atmosphere where the air is much colder. The water freezes into ice and falls, only to be carried back up again by another updraft, where another layer of ice accumulates on the outside. After numerous trips, gaining more and more layers, the hailstone is too heavy to be lifted aloft by the updrafts, and falls to the ground.


What type of clouds produce lightning?

There is a particular cloud that is a thunder cloud. It is easily identifiable. It looks like a bucket of pop corn, only that it's the clouds. It is anvil shaped.


Is cumulonimbus clouds located in the ozone layer?

No, they are not. Only PSC's are located.


Why does a cumulonimbus indicate a tornado?

It doesn't. Cumulonimbus clouds are the clouds of thunderstorms, as they are formed by towering convective cells. Tornadoes are a product of thunderstorms, but only a small percentage of thunderstorms are tornadic.


True or false hail is only observed directly under the cumulonimbus cloud in which its formed?

true


What clouds are dark and so full of water that sunlight cant pass through them?

The only clouds on earth that are like this are cumulonimbus.


Do Stratus clouds produce the most rain?

No, stratus clouds only produce relatively light rain. Cumulonimbus produce the heaviest rain (thunderstorms).


Do low cumulonimbus clouds bring both tornadoes and thunderstorms?

Thunderstorms form from cumulonimbus clouds, but they don't have to be low. Some of these thunderstorms can produce tornadoes, but not all. A thunderstorm is the only thing that can produce a tornado. Tornadoes form best from low-based thunderstorms.
