Tornadoes

A mid-latitude cyclone is a large-scale low pressure system that typically occurs between 30 and 60 degrees of latitude. Such systems are driven by temperature contrasts along fronts. A typical mid-latitude cyclone will have an associated warm front and cold font, which eventually merge into an occluded front. Mid-latitude cyclones often bring stormy weather and sometimes strong winds, but are not necessarily violent or severe. These systems generally last several days.

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-shaped cloud. A tornado is not a self-sustaining storm system, but rather a small-scale vortex dependent on a parent thunderstorm. Tornadoes are violent by definition. Most tornadoes last no more than a few minutes. Tornadoes that last more than an hour are rare.

Antarctica has never recorded a tornado or a tropical cyclone (hurricane or typhoon).

Wind, the movement of air, is driven by pressure differences. Like all liquids and gasses, air tends to move from an area of high pressure to one of low pressure. The more the pressure changes over a given distance, the faster the air moves. Both hurricanes and tornadoes have significantly lower pressure than their surroundings, which exerts a strong pull on the air.

1. A hurricane is its own, self-sustaining storm system while a tornado is dependent on a parent storm cell.
2. A hurricane is typically hundreds of miles wide while a tornado is rarely over a mile in diameter.
3. A hurricane lasts for days, sometimes weeks. A tornado usually lasts no more than a few minutes, never more than a few hours.
4. A hurricane can only develop over warm water while a tornado is most likely to form over land.
5. A hurricane is primarily a tropical phenomenon while tornadoes are more common in temperate and subtropical regions.
6. A hurricane brings a risk of major flooding in addition to powerful winds while a tornado does damage simply from wind and debris.
7. The strongest tornadoes have the fastest winds of any storm, in rare cases over 300 mph. Hurricanes cannot produce such winds.
8. Tornadoes are often made visible by a funnel cloud. Hurricanes do not have such a feature.
9. Tornadoes tend to cause more severe damage than hurricanes, but on a more localized scale.
10. Multiple tornadoes often form in the same storm system in what is called a tornado outbreak. Hurricanes occur individually

No. A typhoon is neither underwater, not a tornado. Rather, a typhoon is essentially the same thing as a hurricane. It is a large and intense tropical storm system that brings powerful winds, torrential rain, and large waves. A typhoon is much larger than a tornado and is its own self-sustaining weather system.

The best course of action is to keep an eye on the weather and the potential hazard. If you see conditions becoming hazardous or if the advisory is upgraded to something more serious then you should take the action such as evacuating or taking cover.

This qualifies as a high-risk outlook.

Such an outlook generally means that the SPC anticipates a major tornado outbreak with the potential for multiple long-tracked and violent tornadoes.

Since the SPC started publishing outlooks online in 2003, only four days have featured 45% or greater tornado outlooks.

Hurricanes last for days or even weeks. The longest lived hurricane on record lasted 31 days.

Tornadoes usually only last a few minutes and are rarely on the ground for over an hour. Some just last a few seconds. The longest lived tornado on record lasted 3.5 hours.

Tornado warnings did not start being issued until the 1950s. Prior to that we did not understand tornadoes well enough to predict them, and forecasters were forbidden from mentioning tornadoes for fear of starting a panic. Even in the modern day a tornado occasionally slips through the cracks. One of the most notable examples came on December 31, 2010 when an EF3 tornado struck the small town of Cincinnati, Arkansas without warning, killing 4 people.

A tornado comes from a type of storm called a rotating thunderstorm, but is not a storm, itself.

The debris in a tornado consists of objects lifted and carried by the winds of the tornado. The debris travels at high speeds. A hard object traveling at such high speeds, even if it weighs only a few pounds, can easily cause a serious or even fatal injury. The debris may also include sharp objects such as splintered wood and broken glass. It is easier for the winds of a tornado to pick up such relatively light, but still dangerous objects than it is to pick up a person, which is why more people die from debris that from being thrown. Additionally, people are more likely to be inside than outside during a tornado. The building they are in will usually provide enough protection that they won't be carried away, but debris that can come through windows and walls or even from the destruction of the building may still prove fatal. Finally, a strong tornado moving through a developed area can produce an enormous amount of flying debris.

Yes, Spring Valley, IL, has tornado activity somewhat higher than elsewhere in the United States. The most recently recorded tornado occurred there in April, 2004. It was ranked as an F4 (violent, intense) tornado that killed 8 people, injured 12 people and caused $8 million in damages.

Tornadoes in 2013 killed 112 people. 55 of them in the United States.

Springfield, Illinois does get tornadoes as Illinois is in a tornado-prone region. Springfield cannot get hurricanes, nor can anywhere in Illinois, as hurricanes cannot maintain their strength over land.

It varies, as all of these storms can potentially become stationary. However, hurricanes move slower overall.

Tornado Watch is where there is a Tornado comming near the area where u live or maybe somewhere else. The news calls it a Tornado Watch. Tornado Watch is where a Tornado comes and people watch when it comes nearest to them so they could keepwatch on what is going to happen.

You get a huge twister mat, then flick the arrow on the wheel showing body parts and colors, then tell the people playing the put whatever body part the arrow landed on, on the accompanying color.

A tornado emergency is a special kind of tornado warning that is issued when a large tornado is threatening a populated area. A tornado emergency indicates a more dangerous situation than an ordinary tornado warning.

Yes, both tornadoes and hurricanes require low air pressure to form and intensify. In tornadoes, the rapidly rotating column of air is driven by the pressure difference caused by the surrounding low pressure. Hurricanes form around a low-pressure center, with the pressure gradient helping to enhance the storm's winds and intensity.

Tornadoes are sometimes called twisters. Some people will also call them cyclones, though this is technically incorrect. If a tornado occurs on water it is called a waterspout.

It depends on how strong the tornado is. If its a weak tornado then most likely it can not, but if it's a very strong tornado it is very possible that it can.

Generally tornado winds are more destructive that hurricane winds. Hurricane winds, however, cause damage over a much larger area than a tornado, so the overall amount of damage may be greater. The worst damage in a hurricane is usually the result of flooding.

Tropical cyclones, extratropical cyclones, and tornadoes are weather patterns that produce winds that rotate around a cener of low pressure in a cyclonic direction. That is clockwise in the southern hemisphere and counterclockwise in the northern hemisphere.

Tropical cyclones, the strongest of which can be called hurricanes or typhoons, are large-scale convective low pressure systems characterized by a warm core. They are driven by the convection within the thunderstorms that make them up. Tropical cyclones get their energy from the heat released as huge amounts of water vapor from warm water condenses. Such cyclones are intimately dependent on this power source and so can only form and maintain themselves over warm ocean water. Tropical cyclones that stray from these areas will weaken and either dissipate or become mid-latitude cyclones. Strong tropical cyclones will often develop a calm, sometimes clear area called an eye. Such a feature is rarely seen in mid-latitude cyclones. Tropical cyclones are generally more intense than mid-latitude cyclones, producing hurricane force winds with greater frequency, and occasionally producing winds over 150 mph. Tropical cyclones are most common in the warmer months.

Mid-latitude cyclones, also called extratropical cyclones, are large-scale low-pressure systems that generally occur between 30 and 60 degrees of latitude and are characterized by a cold core. They are driven by differences in temperature along the boundaries of air masses. These weather systems are connected to fronts, or boundaries between air masses. Unlike tropical cyclone, mid-latitude cyclones are not powered by thunderstorms, though they can still produce them. Mid-latitude cyclones can develop over both land and water and can bring a variety of weather patterns depending on the conditions and time of year. In the colder months they often bring snow and somtimes blizzard conditions. In warmer months they may bring heavy rain and thunderstorms. Sometimes, blizzards occur in the cold portion of the cyclone while thunderstorms occur in the warm portion. Mid-latitude cyclones are generally not as intense as tropical cyclones, but tend to be larger in geographic extent, though they can still produce strong wind. Extratropical cyclones tend to be stronger in the colder months.

A tornado is a violently rotating column of air extending from the the bases of a thnderstorm to the ground. A tornado has some characteristics of a cyclone, but is not a true cyclone. Cyclones, both tropical and extratropical, are large-scale independent storm systems typically hundreds of miles wide. A tornado is a small-scale vortex, rarely over a mile wide and usually much smaller and is dependent on a larger parent thunderstorm. while a cyclone forms and occurs over the course of days, the duration of a tornado is usually measured in minutes. Tornadoes are famous for the typically conical condensation funnel that makes many of them visible, a feature unique to tornadoes and waterspouts. Tornadoes are usually driven by rotation within a thunderstorm, most often a kind of rotating updraft called a mesyclone withing a thnderstorm called a supercell. The storms that produce tornadoes are most often found along or near the fronts associated with a mid-latitude cyclone, but can also occur with a tropical cyclone or in the absense of an organized system. Evidence now indicates that some tornadoes have a feature similar to the eye for a hurricane. A tornado does not produce its own precipitation, though it is usually accompanied by rain and sometimes by hail. As a result, the threat of a tornado comes from its wind. Air in a tornado rises rapidly, unlike the mainly horizontal wind of a cyclone, and twists on a much smaller scale. This makes tornadic winds more damaging than ordinary winds at the same speed. Tornadoes tend to be strongest and occur most frequently in the spring, but show great variability in where and when they occur. They are the most difficult storms to predict. Tornadoes are the most violent windstorms on Earth, with the strongest producing wind gusts over 300 mph.
