In most cases in the northern hemisphere, air spirals counter-clockwise around a tornado and sucks upward in the core center of the tornado. This is typically clockwise in the southern hemisphere.

What happens if a tornado strikes the ground?
Air at ground level will then spiral into the tornado and reach great speeds. Any buildings or trees the tornado hits will be damaged or destroyed by the winds.
Is a tornado torsion?
Yes. When a tornado forms, hot and cold air come together. They spiral around each other at a great speed, which is known as torsion.
What is a whirling wind accompanied by a funnel-shaped cloud?
A whirlwind. Whirlwinds can range from harmless dust devils to violent tornadoes.
Is air pressure inside a tornado is lower than outside a tornado?
The air pressure in a tornado is lower than that outside the tornado. That is why the wind blows toward the funnel.
A vortex of air rising into a cloud?
tornado
Why is it that the middle spiral of a tornado form?
A tornado usually forms from a large column of rotating air called a mesocyclone. A tornado therefore has quite a bit of angular momentum, so air spirals into the it.
Is a tornado a spiral in nature?
A tornado does not have a spiral shape or appearance (except in some cases where helical subvortices form), but the winds in and near a tornado move in a spiral fashion.
What happens if a tornado strikes the ground?
Air at ground level will then spiral into the tornado and reach great speeds. Any buildings or trees the tornado hits will be damaged or destroyed by the winds.
How does the air chase itself in a tornado?
A tornado forms from the rotating updraft of a thunderstorm. The updraft of the tornado creates low pressure that causes air to spiral inward (usually counterclockwise int he northern hemisphere and clockwise in the southern) and then upward.
Winds in a tornado rotate in or out?
Winds in a tornado spiral inward and upward.
How does the wind move in a tornado?
The wind moves in a spiral fashion, moving rapidly toward the center of the tornado in a cyclonic fashion, meaning counterclockwise in the northern hemisphere and clockwise in the southern. In the core of the tornado this wind takes on a more circular pattern. In addition to the spiral movement, wind in a tornado moves rapidly upwards. There may be fairly calm area of sinking air at the center of some tornadoes. In these tornadoes, a series of smaller whirlwinds can sometimes develop inside the tornado. These spinning columns of air circle the tornado's center, moving with the rotation.
Do tornadoes have a spiral-shaped wind path?
The air in and near a tornado generally follows a spiral path as it moves inward and upward around the tornado's center of rotation. In some tornadoes, however, it is more complicated than this as there may be smaller subvortices embedded in the main vortex. The tornado itself usually moves in a fairly straight line.
Is a tornado torsion?
Yes. When a tornado forms, hot and cold air come together. They spiral around each other at a great speed, which is known as torsion.
Why tornado is spiral in shape why do cyclones not have a spiral shape?
The opposite is true. Cyclones ave a spiral shape while tornadoes generally do not. In both a tornado and a cyclone, air spirals in toward a center of low pressure. A cyclone, however, is many times larger than a tornado. Therefore, variations in moisture and air temperature a few miles to a few hundred miles across can be contained within it. These variations give rise to variations in cloud cover, which get twisted into a spiral shape. Tornadoes, which rarely exceed a mile in diameter, are too small to contain such large-scale variations.
Are all tornadoes spiral?
Tornadoes generally don't have a spiral shape. But the winds in and near a tornado always move in a spiral pattern.
What is a 7 letter word for wind spiral?
Tornado.
What is the difference between a tornado and a microburst?
A tornado is a violently rotating column of air. Air in and around a tornado moves inward and upward in a spiral pattern. Unlike in a microburst, tornado damage usually follows a discrete path. A microburst is a sudden and intense downdraft within a severe thunderstorm that produces powerful winds. Unlike a tornado the winds in a microburst travel downward and outward and do not rotate.
