They are called cumulonimbus clouds.
Cumulonimbus
dry lands
cumulonimbus
Cirrus Clouds. They form about 9kms above sea level and are composed of ice crystals
Cumulonimbus clouds.
Cumulonimbus. Most notably cumulonimbus incus.
Tornadoes are typically produced by thunderstorms called supercells.
the weather that cumulonimbus brings is thunderstorms
Most storms, particularly in summer they will be cumulonimbus.
cumulonimbus
Cumulonimbus clouds have a large and tall horizontal appearance. They are capable of producing severe weather conditions such as thunderstorms and hailstones.
A wall cloud.
No, it can not happen. You will always need a cloud to form a tornado. The kind of cloud that a tornado uses is a cumulonimbus cloud.
Cumulonimbus clouds form lightning
No. Tornadoes need thunderstorms to form and by definition the vortex of a tornado must connect with both the ground and the bottom of a cloud. However there is another kind of whirlwind called a dust devil. Dust devils look somewhat like tornadoes and typically form on hot, sunny days, especially in desert areas. However they are not considered tornadoes because they do not connect with the cloud base and are usually too weak to cause any damage.
No. All thunderstorms require an updraft, but that updraft does not need to rotate. A supercell is not a rotating updraft, but rather a particular kind of thunderstorm with a rotating updraft.
If local convection, or a pressure front, causes the cloud to change elevation, the water vapor will form into a different cloud type consistent with that altitude.
Tornadoes form during thunderstorms, usually an especially severe kind called a supercell. The storms take the form of anvil-shaped cumulonimbus clouds. The sides of these storms sometimes look like stacked plates. However, if you are observing a tornado, you will be under the storm, and will not be able to observe this structure. The area of intrest will revolve around the wall cloud, which is a rotating mass of clouds that hangs below the main cloud base. The tornado itself will produce a funnel, which may be cone, needle, rope, or column shaped. However, not all tornadoes come with a wall cloud or condensation funnel, and these features, even if present, may be obscured by rain.
