Tornadoes

That is called a tornado. It is a rapidly rotating column of air that is in contact with both the surface of the Earth and a cumulonimbus cloud.

When a tornado begins to dissipate it usually shrinks. Usually this means a tornado is weakening , though some tornado intensify at this point. As the tornado continues to get smaller the funnel may becomes bent and elongated, giving it a rope like appearance. In fact, this process is called "roping out" As this happens the tornado will continues to shrink and weaken until it completely dissipates.

Tornadoes are storms, and thus naturally occurring.

Schools should have designated tornado shelter areas identified and clearly marked. Regular tornado drills should be conducted so students and staff know what to do in the event of a tornado. Also, monitoring weather alerts and having a system in place to notify everyone in the school of a tornado warning is essential for keeping everyone safe.

An F4 tornado can be devastating. An F4 tornado will level well-built houses and strip bark from trees. Such tornadoes have been known to wipe out large sections of cities and towns. While most of the worst tornadoes in U.S. history have been F5s, several F4 tornadoes are on that list as well.

In many cases there is too much dust flying around to see much of anything. The funnel itself may look like a very dense fog up close. In some cases, the inside of the tornado may look like a hollow tube with a calm center.

Tornadoes generally travel from southwest to northeast in the United States. However, tornadoes can move in any direction depending on the surrounding weather patterns and conditions.

No town gets hit by tornadoes on an annual basis. Moore has been hit by 12 recorded tornadoes since 1950.

The Saffir-Simpson wind scale predicts the potential damage and intensity of a hurricane based on its sustained wind speeds. The scale ranges from Category 1 (74-95 mph) to Category 5 (157 mph or higher), with each category indicating increasing levels of potential damage.

Floods, hurricanes, and tornadoes are all extreme weather events that occur due to various atmospheric conditions like moisture, temperature, and pressure changes. They are caused by factors such as heavy rainfall, strong winds, and rapid air movement. These events result in significant impacts on the environment and human populations.

The coldest I'm aware of was a tornado outbreak in SW Oklahoma on February 22, 1975. Several F2 tornadoes formed in the early morning hours when temperatures were near or just below 40 degrees Fahrenheit. There have been other incidents of severe thunderstorms and tornadoes when temperatures were in the 40's and occasionally even the 30's.

Theoretically a tornado or severe thunderstorm could form at any temperature so long as atmospheric instability is high enough, but the levels of instability from the parent storm system required to form a tornado at say, 25 degrees, would be much higher than anything experienced on Earth.

A warning is generally the worse advisory. Although it differs depending on which sort of watch or warning is issued, a watch means a particular event is possible. For example, if there is a tornado watch, it means that conditions are favorable for a tornado to form. A warning means the event is expected or probable. In a tornado warning, for example, it means that a tornado has been spotted or is forming.

By the estimates of the Enhanced Fujita scale EF0 tornado winds start at 65 mph. However, this is only an estimate.

It is rare to get direct measurements from inside a tornado.

Note, however that whether or not a tornado has occurred is not defined by the wind speed, but by the manner in which it moves. A tornado is a violent vortex of wind in contact with the cloud base and the ground.

No. All hurricanes and other tropical cyclones above tropical depression strength get named, however extratropical cyclones are not named. Tornadoes never get names.

Such statements generally cannot be applied categorically, as the severity of impact of any of these events can vary widley.

To start off, though, we must establish that a hurricane is a kind of cyclone, specifically an intense tropical cyclone. Hurricanes and other intense tropical cyclones such as typhoons are really the same thing. These storms are the most intense variety of cyclone and do have the most potential for death and destruction of all the events discussed here. However, not all tropical cyclones live up to their full destructive potential. Cyclones, including hurricanes, are large weather patterns that impact large areas.

Mid-latitude cyclones are rarely as intense as even a minimal hurricane, but they can still have significant effects including blizzards, floods, and severe weather and tornado outbreaks.

Tornadoes are a different phenomenon. They are small-scale weather events. Their effects are generally very localized, but the severity of damage in the small areas they hit is generally worse. So, while a hurricane may cause moderate damage across several states, a tornado can cause major damage limited to a single town.

they are no advisory in tornadoes only a warning or watch a warning means that Doppler radar and storm watchers indicated tornado formation and a watch is Doppler radar indicated weather conditions producing severe thunderstorms that can produce tornadoes

Stone County, Missouri experienced 8 tornadoes from 1995 to 2010.

Tornadoes are often, but not always preceded by heavy rain and hail. This hail can sometimes be very large.

Nebraska typically experiences around 50-60 tornadoes each year. This number can vary depending on weather patterns and conditions in a particular year.

In long term forecasts, which predict overall weather patterns, different instruments are used including thermometers, barometers, hygrometer and anemometers to measure temperature, pressure, humidity, and wind speed and direction. Some of these instruments can be mounted on weather balloons. Information such as this is then fed into supercomputers that run forecast models. This can be used to predict if overall conditions favor the formation of tornadoes, but not where specific tornadoes will occur.

In the short term, doppler radar can be used to detect rotation and, with recent advances, tornadic debris, within a thunderstorm. This can be used to determine if a tornado may form soon, or if one is already occurring.

It is not recommended to close the fireplace flue during a tornado. Doing so can lead to increased pressure inside the house, which may cause structural damage. It is best to keep the flue open to prevent any potential issues.

Tornadoes that are difficult to spot (due to night time hours) and typically occur during the hours when the majority of people are asleep. This tends to make people more vulnerable because they're not as alert and don't take precautionary measures because they're uninformed.

Buffalo were separated into two groups because they could not pass the transcontinental railroad tracks. This caused the death of many buffalo (passengers on the trains shooting the buffalo for fun while they rode by also contributed to this greatly). Native Americans were displaced and subsequently relocated, if they were not killed. Many people died due to battles in which the Native Americans defended their homeland (think Custer's Last Stand). Natural resources where quickly consumed. The land soon became unfertile due to excessive agricultural use.
