Tornadoes

A tornado or twister is a violent, rotating column of air which typically has a speed ranging from 177 km/h to over 480 km/h. This devastating windstorm is usually characterized by its funnel-shaped cloud that extends toward the ground.

Is it possible for a tornado to freeze?

User Avatar
No. A tornado is made up primarily of air. The freezing points of the gasses in air are far below anything found naturally on earth.

How is a tornado like a cyclone?

User Avatar
Both have low pressure centers and, with the exception of a very small percentage of tornadoes, have cyclonic rotation, meaning they rotate counterclockwise in the northern hemisphere and clockwise in the southern.

Why do hurricanes create tornadoes?

User Avatar
When a hurricane hits land the lower portions of the storm weaken faster than the upper portions. This creates rolling air called wind shear, which gets taken into the updrafts of thunderstorms in the outer regions of the hurricane, turning the storms into supercells with rotating updrafts called mesocyclones. The rotation in the mesocyclones then tightens and intensifies to form tornadoes. Aside from the source of the wind shear this process is essentially the same as how tornadoes are formed under other circumstances, only the storms are usually along a cold front.

no you cant weather cannot be controlled by people but preventing the impact is possible

How should structures be built to overcome the forces caused by tornadoes?

User Avatar
The way in just plain logic is that there should be a Strong inner structure plus with a strong outer Build. the reason for the inner is because of pressure under a tornado Many houses collapse inward in some cases so it is a smart idea hope you think this helps!

How many annual deaths in a tornado?

User Avatar
The United States suffers 60 tornadoes deaths in an average year. This number is gradually falling as warnings improve. Globally tornado deaths are generally not much higher as the United States sees most of the violent tornadoes.

Is the size of a tornado affected by water temperature?

User Avatar
No, especially considering that most tornadoes form over land, not water.

Hurricanes and tornadoes are both example of violent, rotating storms.

What makes a thunderstorm become a tornado?

User Avatar
A thunderstorm does not become a tornado, it produces them. How exactly thunderstorm produce tornadoes, but this is the best theory so far. First you need a special kind of thunderstorm called a supercell. This is a powerful, rotating thunderstorm. The rotation is especially strong at an updraft called a mesocyclone. If the strong strengthens fast enough a special kind of downdraft may descend from the back of the storm and wrap around the bottom part of the mesocyclone. This forces it to become smaller and can bring it down to the ground. As the rotation gets smaller it speeds up, producing a tornado.

Why should you stay low to the ground if you are caught outside during a thunderstorm?

User Avatar
There could be positive charges on the ground so chouch on all 4s & keep your head low. Do not lie on the ground full-lengh.

How do scientists safley study tornadoes?

User Avatar
I know one team who gets INSIDE a tornado using this really cool vehicle ; the Tornado Intercept Vehicle or TIV. They do it for 2 reasons; 1 for a IMAX film and 2 for data. Other storm chasers use probes that sits in a tornado's path. However, direct intercepts are rare. The best and generally method we have for studying tornadoes is using Doppler radar, which uses radio waves to gather data from a distance. Additionally, scientists will construct computer models of thunderstorms, one both with and without tornadoes.

How does a funnel in a tornado form?

User Avatar
The tornado pulls in moist air from the rainy portion of the parent storm. When the air is suddenly decompressed inside the tornado it cools and the moisture condenses, forming a cloud.

What kind of damage does an EF5 tornado do?

User Avatar
EF5 damage is total devastation. Well constructed houses are wiped clean off their foundations and can be carried or thrown great distances. Virtually nothing can withstand the full force of an EF5. Even concrete structures are heavily damaged.

you can get in your basement, hide in the bathtub with a mattress on you,hide in the closet,run out the house,lay in the lowest part of the house with a matress on you,

Is a walkout basement safe during a tornado?

User Avatar
It depends on the strength of the tornado, but it is not as safe as a fully underground basement. In most cases it would be safe, especially if you can get into a room that is in the underground portion of it.

When did the tornado in New York happen or who died in it?

User Avatar
If you are referring to the most recent tornado to hit New York City there were two: And EF0 with estimated winds of 80 mph and an EF1 with estimated winds of 100 mph. The EF1 was the killer Aline Levakis died when a tree fell on the car she was in.

Where do tornadoes occur?

User Avatar
Tornados can occur anywhere there is weather warm enough to generate the storms that spawn tornados. If an area can have a thunderstorm, it can have a tornado.
Asked in Tornadoes, Personal Safety and Security

What should you do during a tornado to be safe?

User Avatar
Safety tips during a tornado include: Stay inside at all times if possible! Do not go anywhere near windows. The best place to be is in a basement or storm cellar. Crouch down in a corner facing a wall with your head covered. If you do not have an underground shelter get to the lowest floor and find an interior room The bathroom is a good place, as they normally have the fewest windows and the plumbing can help reinforce the walls. If possible, take cover in the bathtub. Abandon vehicles and mobile homes and vehicles for sturdier shelter. Nearly half of all deaths from tornadoes occur in trailer homes, which offer little protection. If caught outside with no access to shelter take cover in a ditch. Do not try to outrun the tornado. Do not attempt to open your windows, Do not seek shelter under a bridge. Stay away from tall objects Cover you and your family in blankets in case of flying glass or objects. Avoid being near windows or around any external wall (one that separates the inside from outside). It is a good idea to keep a battery powered radio (with fresh batteries) with you so you know where the tornado might be located and when the threat of a tornado has passed. If you can get one quickly, wearing a bicycle or football helmet can protect you from head injuries.

Why do tornadoes form over open fields?

It just so happens that the best climate for producing tornadoes is the type in which grasslands develop. Many tornadoes have also touched down in forests as well.

A tornado on water is called a waterspout, not a hurricanes as some might say, which as a completely different type of event.

What atmospheric conditions cause tornadoes?

User Avatar
The formation of tornadoes is complicated. First, a condition called wind shear, in which the speed and/or direction of the wind changes with altitude. If the shear is strong enough it can essentially tilt a thunderstorm, this separates the updraft and downdraft of the thunderstorm, preventing them from interfering with one another. This allows the storm to become stronger and last longer. Additionally, if the wind shear is strong enough it can start the air rolling in what is called horizontal vorticity. This horizontal vorticity can then be turned vertical by a thunderstorm's updraft. When this happens, the thunderstorm may start rotating. The rotation is especially strong in an updraft called a mesocyclone. If the storm intensifies rapidly enough, a relatively warm downdraft called a rear-flank downdraft or RFD can wrap around the bottom part of the mesocyclone. This can then tighten and intensify its rotation and bring it down to the ground to produce a tornado. In addition to tornadoes, very heavy rain, frequent lightning, strong wind gusts, and hail are common in such storms.

How early can a tornadoes be predicted?

User Avatar
Tornadoes are very difficult to predict. The possibility of tornadoes occurring can be predicted hours ahead of time based on general weather conditions . In this case a tornado watch is issued. But within a large area there is no way of known with any certainty where or when a tornado will strike or if one will occur at all. If a tornado is occurring or a storm may soon produce a tornado, a tornado warning is issued for an area about the size of a county. Even then, meteorologists cannot be certain where or when a possible tornado will strike.
