How does a wall cloud form?
A wall cloud forms when the rotating updraft of a supercell thunderstorm, called a mesocyclone, draws in moist air and causes the moisture to condense. The wall cloud marks the strongest part of the mesocyclone.
What is a column of violently rotating air in the shape of a funnel cloud?
A tornado
How is a tornado cloud different from other clouds in the sky?
A tornado itself is not a cloud, though it is often made visible by one. A cloud is a mass of tiny water droplets or ice crystals suspended in the air. The vast majority of clouds are not violent in any way. A tornado is a violently rotating vortex of wind that connects to the base of a thunderstorm and the ground, capable of causing significant damage. The cloud associated with a tornado is called a funnel. This cloud is unique in terms of the violent rotation with in it and for the fact that it will often be in contact with the ground.
Describe how tornadoes develop what is the difference between a funnel cloud and a tornado?
Tornadoes develop when wind shear (horizontally rolling air) is turned vertical by a thunderstorm and starts it rotating. This turns the thunderstorm into a supercell, a thunderstorm with a powerful, rotating updraft called a mesocyclone. If conditions are right, a downdraft called a rear-flank downdraft or RFD will descend from the storm and wrap around the mesocyclone, tightening and intensifying it and extending it down to the ground, producing a tornado. A funnel cloud has the general form of a tornado but is not in contact with the ground, while a tornado extends all the way from the clouds to the ground with winds capable of producing damage.
Why would a tornado start rotate?
Tornadoes rotate because they form from a larger mass of rotating air. In most cases this rotation comes from a mesocyclone, the rotating updraft of a supercell thunderstorm. The mesocyclone can tighten and intensify to produce a tornado. Some tornadoes form from a broad, weak circulation at ground level, which gets caught in a thunderstorm updraft and turned into a narrower but stronger vortex.
What is a violently rotating column of air stretching from cloud to ground?
a rotating column of air that extends from a thunderstorm to the ground is a Tornado
What is a rotating air mass in a thunder storm cloud?
one word;mesocyclone
Is a tornado a cloud?
No. A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground. A tornado is often, but not always made visible by a funnel cloud. But the tornado is not the cloud itself.
How does a wall cloud form?
A wall cloud forms when the rotating updraft of a supercell thunderstorm, called a mesocyclone, draws in moist air and causes the moisture to condense. The wall cloud marks the strongest part of the mesocyclone.
What is the difference between a shelf cloud and a wall cloud?
A shelf cloud is produce by thunderstorm outflow, resulting from rain cooled air being force downward and outward in a thunderstorm. A shelf cloud may indicate that strong straight-line winds are coming A wall cloud is found in the mesocyclone, or rotating updraft of a type of thunderstorm called a supercell. This is an indicator that a tornado may soon form.
What are supercells and tornadoes?
A tornado is a violently rotating an often destructive column of air extending from the base of a thunderstorm to the ground. They are often made visible by a condensation funnel and a cloud of dust and/or debris. A supercell is a type of very powerful, rotating thunderstorm typically defined by a rotating updraft called a mesocyclone. They are the strongest thunderstorms on earth. The majority of tornadoes are produced by the mesocyclone of a supercell.
What forms when a warm air mass collides with a cold air mass?
thunderstorm
What is thunderstorm cyclone tornado?
A thunderstorm is any rain storm that produces thunder and lighting. They are typically the result of a rising mass of warm, moist air in a cumulonimbus cloud. A cyclone is a large-scale low pressure system with a defined center of rotation, turning counterclockwise if it is in the northern hemisphere and clockwise in the southern hemisphere. There are tropical cyclones, which include hurricanes and typhoons, and mid-latitude cyclones, which occur in temperate climates. A tornado is a violently rotating and often destructive column of air extending from the base of a thunderstorm to the ground, often accompanied by a funnel-shaped cloud.
What is a tornado and what makes it occur?
A tornado is a violently rotating column of air extending from the base of a thunderstorm to the ground, often made visible by a funnel or cone shaped cloud. A tornado occurs when rolling air called wind shear is turned vertical by a thunderstorm. This creates a supercell, a storm with a strong, rotating updraft called a mesocyclone. Under the right conditions a downdraft can wrap around the mesocyclone, forcing the rotating into a tighter, more intense vortex: a tornado.
What is a rotating cone shaped column of air extending downward from a cloud?
Funnel cloud
Are tornadoes and avalanches similar?
No. An avalanche is a large mass of snow and ice sliding down the side of a mountain. A tornado is a violently rotating column of air extending from a thunderstorm to the ground.
What is a huge rotating column of air that descends from a cloud?
A tornado.
