Tornadoes

The appropriate response to a severe weather watch is to stay informed by monitoring updates from trusted sources, prepare an emergency kit including food, water, and important documents, and review your family emergency plan. Be ready to take quick action if a warning is issued.

Tornadoes are more likely to lift lighter objects as they generate an upward force with their strong winds. Heavier objects may be more difficult for tornadoes to lift unless they are caught in the vortex of the tornado's winds.

A tornado is officially confirmed when a rotating column of air reaches the ground and makes contact with the surface. This contact creates the characteristic funnel cloud shape that is associated with tornadoes.

It varies widley from one tornado to another, and most tornadoes will vary in strength during their time on the ground. Weak tornadoes may have peak winds of only about 65 mph. In rare cases, peak winds may exceed 300 mph. Generally weaker tornadoes are more common.

Very few tornadoes ever have their winds measured. Most of the time the wind speed is estimated based on the damage that is done.

Most actual measurments, when they do occur, are taken using mobile Doppler radar.

Precipitation is a key factor in the formation of tornadoes. Tornadoes often form within thunderstorms, where strong updrafts and downdrafts can lead to the development of a rotating column of air. The presence of precipitation can add instability to the atmosphere, enhancing the conditions necessary for tornado formation.

As with all weather on Earth, the ultimate source of energy is the sun.

The sun heats the Earth, which create masses of warm, moist air that act as fuel for thunderstorms. Under the right conditions, these storms can sometimes produce tornadoes.

The tornado scale, known as the Enhanced Fujita Scale (EF-Scale), was developed by a team led by Dr. T. Theodore Fujita in collaboration with Allen Pearson. It was an update to the original Fujita Scale of tornado intensity.

In the Northern Hemisphere, hurricanes and tornadoes typically rotate counterclockwise. This is due to the Coriolis effect, which causes moving air to be deflected to the right in the Northern Hemisphere.

Yes, typically the funnel cloud forms in the air as part of the rotating updraft within a thunderstorm. As the conditions align and intensify, the funnel cloud may extend and reach the ground, officially becoming a tornado.

The vast majority of tornadoes in the northern hemisphere spin counterclockwise. Most tornadoes in the southern hemisphere spin clockwise.

Unlike other extreme wind events, air in a tornado moves rapidly upward in addition to rotating rapidly. This upward movement of air creates and upward force, which can lift objects off the ground. The stronger the tornado, the larger the things that can be picked up.

The path of a tornado can be unpredictable and one can overtake you more quickly than expected. Once caught in a tornado, a car offers little protection and you are actually better off taking cover in a ditch.

In terms of evacuating, a study house, especially one with a basement, offers far better protection. Attempting to evacuate a populated area would likely lead to traffic jams and possibly accidents, which would slow the evacuation with potentially catestrophic results. This is compounded by the fact that the pek of daily tornado activity often coincides with rush hour.

One of the most infamous cases took place on April 10, 1979 when an F4 tornado struck Wichita Falls, Texas. Some people attempted to fleed the tornado. Of the 42 people killed by the Wichita Falls tornado, 25 died in their vehicles. Some of the victims ended up driving directly into the tornado's path, while it completely missed their homes.

More recently, on May 31, 2013, a massive tornado was tracked as it headed toward Oklahoma City. Some people attempted to evacuate, only to become struck in rush hour traffic, leaving them completely vulnerable if the tornado should come their way. The tornado started moving toward a densely packed section of highway, but fortunately dissipated before it got there. This tornado killed 8 people, including 4 storm chasers, all in vehicles. It is believed that, had this tornado continued into heavy traffic, the death toll might have exceeded 500.

Tornadoes and hurricanes are both examples of severe weather phenomena known as cyclones. Tornadoes are characterized by strong rotating winds that form from thunderstorms, while hurricanes are large tropical cyclones with low-pressure centers that develop over warm ocean waters.

The intensity of a tornado is primarily determined by the Enhanced Fujita Scale, which takes into account the damage caused by the tornado. Factors such as wind speed, path length, and width of damage are analyzed to assign a rating on the EF Scale, ranging from EF0 to EF5, with EF5 being the most intense.

Tornadoes produced by spheres are created due to the spinning motion of the spheres causing a swirling effect in the air. As the spheres move, they create a low-pressure area that can draw in surrounding air and create a vortex. This vortex can then intensify into a tornado under the right conditions.

Storm chasers help save lives by collecting data to improve forecasting accuracy, which allows for better warnings and preparations for severe weather events. Their research helps improve our understanding of how storms develop and behave, leading to more effective emergency response efforts and potentially reducing the impact of dangerous weather on communities.

The center of a tornado is an area of intense low pressure.

No. Although the eye of a tornado is calm, you have to get through the extreme winds of the core to get in and out. The eye of a tornado is small enough that unless the tornado is large and slow-moving, you will not be in the eye for more than a few seconds.

Hurricanes can spawn tornadoes within their outer rain bands, known as tropical cyclone tornadoes. On average, about 100-200 tornadoes are reported each year in the United States due to hurricanes and tropical storms. These tornadoes tend to be weaker and short-lived compared to traditional tornadoes.

A tornado rotates violently, causing destruction to buildings and structures in its path. It can reach wind speeds exceeding 200 mph, creating a powerful vacuum that can lift heavy objects and debris. Tornadoes can also produce large hail and intense lightning storms within their vicinity.

If caught in a tornado it is best to get as low as possible. Preferably in a basement or cellar. If not you should got to an interior room or hallway on the lowest floor.
Go to a basement or cellar and crouch down facing a wall. If you don't have one get to the center part of your house away from windows. Abandon cars or mobile homes for sturdier shelter. If caught outside with no access to shelter take cover in a ditch as a last resort.

A typhoon in the northern hemisphere rotates counter-clockwise, in contrast to a typhoon in the southern hemisphere which rotates the other way (i.e., clockwise) as explained by the Coriolis effect.

During a tornado, heavy rain and hail are the most likely types of precipitation that may fall. Tornadoes are often associated with severe thunderstorms that can produce intense rainfall and hail as the storm system intensifies.

No. Precipitation is water in some form (either liquid or frozen) falling from the sky. This may include rain, freezing rain, snow, sleet, graupel, or hail. A tornado does not meet this criterion. A tornado consists of a vortex in which air rapidly spirals inward and then upward. A tornado can be considered a type of whirlwind or wind storm.
