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.

∙ 12y agoWhat is seldom known is that, rain and snow happen first upward. It is only when the air further cools down by the adiabatic effect of a lesser pressure aloft that raindrops or snowflakes form. When they are big enough to overcome the ascension, the fall as precipitation.
Hail occurs when the air is very unstable, i.e. the difference of temperature between the ground and the top of the troposphere is great. When that happens, the rising air of a convection never manages to cool down enough to stop rising and it does so all the way up. When that happens, the friction of the ice crystals in the cloud may even form static electricity and a thunderstorm. This type of cloud is called a cumulonimbus and sometimes a towering cumulonimbus.
It is only in those conditions that raindrops keep falling "upward" until they grow very big and freeze into pellets of ice, when reaching the tropopause and eventually come down as hail.

How do hailstones start?
rain.
What causes hailstones to fall from the sky?
hailstones fall out from the sky because when there is thunder or lightning it attacks it through stupid things
What does a cumulonimbus cloud produce?
A cumulonimbus cloud produces rain.
What is the cloud that produces hail?
Hail comes from cumulonimbus clouds.
What type of clouds do thunder storms form in?
Cumulonimbus clouds Cumulonimbus clouds.
What kind of a cloud is cumulonimbus?
Cumulonimbus clouds have a large and tall horizontal appearance. They are capable of producing severe weather conditions such as thunderstorms and hailstones.
What clouds do tornadoes develop from?
tornadoes develop from cumulonimbus clouds.
How do hailstone become so large in 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.
What term describes layered round formations of ice which form in cumulonimbus clouds?
Hail A+
Are cumulonimbus clouds associated with warm fronts?
Cumulonimbus clouds can develop along warm fronts, but are more common along cold fronts.
Which clouds develop tornadoes?
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.
Snowflakes and hailstones were once water vapor describe what happens to the vapor to form snowflakes and hailstones?
Water vapor form snowflakes when the temperatures in the air are above freezing and the air should be unsaturated. The water vapor to create hailstones start inside a cumulonimbus cloud and super cooled liquid water are caught in a strong updraft. The cycle continues to increase the size of the hailstone, then eventually falls to the earth's surface.
What is the relationship between a cloud and a tornado?
Tornadoes develop from thunderstorms, which are cumulonimbus clouds.
How does tornadoes develop commonly in thick cumulonimbus clouds?
By swirling over by the clouds
Where would you expect cumulonimbus clouds to develop most?
In the sky especially when a storm coming
When does acid rain occour?
it occurs when smoke goes into the clouds if its about to rain it mixes with the cloouds and if rain falls it cauases acid rain it occurs when smoke goes into the clouds if its about to rain it mixes with the cloouds and if rain falls it cauases acid rain
Does a tornado come from a cumulonibus cloud?
Yes. Tornadoes are produced by thunderstorms, which from from cumulonimbus cloud. Usually a wall cloud and then a funnel cloud develop at the base of a cumulonimbus cloud before a tornado touches down.
