How does a landspout that flatens crops form?
A landspout is a type of tornado that forms from the bottom up, unlike traditional tornadoes that form from the top down. When a landspout touches down over crops, the swirling winds can flatten them due to the strong rotational forces it generates. This can occur when the touchdown point of the landspout coincides with a field of crops, leading to damage from the intense winds.
Explain how a non- supercell tornado such as a landspout might form?
Landspouts form by mechanisms similar to waterspouts and dust devils. The process starts with a developing thunderstorm. The updraft creates a localized area of slightly lowered pressure, which draws air in. Wind passing through develops some vorticity at ground level owing either to a broad, gentle rotation or variations in wind speed. If this rotation gets caught in the updraft of a developing storm it can contract and rotate faster as angular momentum is conserved. The result is a fairly intense vortex that is drawn upward into the developing storm. Now a landspout has formed.
What is a sideways tornado called?
A sideways tornado is called a landspout. Unlike traditional tornadoes, landspouts form from the ground up and do not require a rotating thunderstorm to develop. They are typically weaker than traditional tornadoes but can still pose a risk to property and life.
Can you have tornado's without thunder storms?
Tornadoes typically form within thunderstorms as a result of strong updrafts and wind shear. It is rare but possible for tornadoes to form without a thunderstorm, such as in the case of landspout tornadoes which develop from different processes, like boundaries of air masses colliding.
Do tornadoes always come from a wall cloud?
No, tornadoes can occur without a visible wall cloud. While a wall cloud can be a precursor to tornado formation, tornadoes can also develop from other types of storm clouds or even from the cloud base itself.

How long does a landspout tornado last?
Waterspouts typically last about 10 minutes.
Is a land spout a waterspout on land?
Yes, a landspout is essentially a waterspout on land.
How big are landspout tornadoes?
Tornadoes come in many different sizes of funnels. Some funnels can be only a few feet wide and some could span a few miles wide.
When is a tornado called a downspout?
Never. A downspout is completely different from a tornado. It is a pipe that drains water from a rain gutter. A tornado on water is called a waterspout. A tornado that forms without a mesocyclone is a landspout.

Is a land cyclone another name for a tornado?
No. Although some people refer to tornadoes as cyclones this is incorrect. A cyclone is a large scale low pressure system A tornado is a small scale circulation spawned from a thunderstorm. However, there is one type of tornado known as a landspout.

Can a dust devil develop into a tornado?
No. Dust devils are whirlwinds that form from low-level convection in the absence of a thunderstorm. Tornadoes form from thunderstorms. However, on rare occasions dust devils can cause minor damage with winds comparable to those of an EF0 tornado. Landspout tornadoes can sometimes look rather like dust devils.
Do tornadoes always come from a wall cloud?
No, tornadoes can occur without a visible wall cloud. While a wall cloud can be a precursor to tornado formation, tornadoes can also develop from other types of storm clouds or even from the cloud base itself.
What word means a tube of violently spinning air that touches the ground?
The most notable example is a tornado, which is a funnel cloud that reaches the ground. Over water, this can manifest as a much less violent phenomenon called a waterspout (a non-cyclonic waterspout over land is called a landspout). Other smaller forms of rotating spinning air are called whirlwinds and dust devils.
