Tornadoes are a rotating column of air extending from a thunderstorm to the ground. Tornados have a funnel shape, have a smoky look to them, turning clockwise and may have multiple vortexes which will be inside, spinning in the centre of the main tornado. A tornado can range from an instant to serval hours and the average amount of time it can go for is five minutes.
A tornado sounds like a jet engine or a freight train and can be very loud.
A tornado forms by the combination of warm, moist air and cool, dry air which creates instability in the atmosphere. The change of wind direction and increasing wind speed creating an invisible, horizontal spinning effect in the lower atmosphere. Most tornados form from thunderstorms but some form from

A current technology that is currently being used to detect, monitor and predict tornados is the Doppler radar. The Doppler radar sends out electromagnetic wave fields that are reflected back to the radar and the amount of energy that is reflected back tells us things about the thunderstorm, show us how the wind is blowing and how heavy the rain is. The radar can also track the path of the thunderstorm and can show us if it may form into a tornado. Algorithms are used to identify and analyse the Doppler radar data, these algorithms are called WSR-88D Mesoscale Detection Algorithm. The algorithms are then put into information that is easier for forecasters to read and identify the dangerous weather that needs to be told to the human population.
A "hook echo" describe a pattern that shows up in radar images. A hook is often associated with a mesocyclone and can indicate favourable conditions for a tornado. Tornado Vortex Signature (TVS) is an another pattern that shows intensely concentrated rotation and appears on the radar before it touches the ground. The tornadoes are also predicted before it hits and ranked after it hits by the Fujita F-scale. The Fujita scale estimates wind speed based on the extent and severity of damage because most technologies don't outlast the devastating

The current technology is also helping us to see what impacts tornadoes are going to make ahead of time and as technology is improving as time goes on, this will slowly improve. The Fujita F-scale and the Doppler radar help us to better understand the natural disaster that is about to, is or has occurred. The current technology also helps to provide the risks and troubles that may occur before the tornado may form and warnings when the tornado has form and is causing danger to human life and
Although the tornado of 10 June 1938 has been known about, at least anecdotally, within the scientific community since it was brought to light in 1939 by Metro-Goldwyn-Mayer, this potentially rich source of historic information has lain fallow. It is within this rich field of mobile, American thinking that we undertake this effort. A team of scientists with courage, brains, and even heart brought the resources to bear on the challenge.
Many scientists often find themselves wondering if the tri-state tornado was really a single massive tornado or if it was part of a family of tornadoes that continuously evolve from one supercell to another. Only one factor stands in the way of this theory and that is a cyclical supercell usually has breaks in its destructive path. The tri-state tornado's path of damage appeared to be continuous despite two slight decreases in the destruction. One of which was near the onset of the storm, and one near the demise. No matter which is believed, one thing is for certain, and that is a storm like the tri-state tornado could very well happen again, but there is no telling when or where it may occur.
According to Webster’s Dictionary, a tornado is a rotating column of air accompanied by a funnel shaped downward extension of a cumulonimbus cloud and having a vortex several hundred yards in diameter whirling destructively at speeds of up to three hundred miles per hour. There are six classifications of tornadoes, which are measured on what is known as the Fujita Scale. These tornadoes range from an F0 to an F5, which is the most devastating of all. Abnormal warm, humid, and oppressive weather usually precede the formation of a tornado. Records of American tornadoes date back to 1804 and have been known to occur in every state of the United States.
The 1953 Waco Tornado was the deadliest tornado in Texas since 1900. The violent and deadly twister ripped through the downtown area killing and injuring hundreds. 600 homes were destroyed and 5 people were hit and killed in cars.Injured people were 597 and 114 killed.
Tornadoes, also called twisters or cyclones, are a localized, violently destructive windstorm occurring over land, and characterized by a long, funnel-shaped cloud extending toward the ground and made visible by condensation and debris. They come in many different shapes and sizes, but are typical in a funnel formation, where the narrow end makes contact with the earth. Most don’t reach winds over 110 miles per hour (177 km/h) or have a path wider than 250 feet (76m), and most only travel a few miles on ground before dissipating. Although, some can reach winds as high as 300 miles per hour (483 km/h) or higher, have a path that can be as wide as two miles (3.2 km) or more, and can travel for dozens of miles on the ground before dissipating.
Although Greensburg was almost entirely destroyed, the storm helped to reinforce the important role that storm chasers play in the tracking and warning process of severe weather. By having well-trained, experienced people in the field, meteorologists and weather services are better able to track the exact location and characteristics of tornadic events, relaying that information to the public faster and more accurately than ever before.
I would like to start out by what we know about tornados and outbreaks, and what is said to be the cause of such catastrophic events, such as the outbreak that occurred November 17th in the Midwestern, portion of the United States. Tornado outbreaks occur when there are multiple tornados that are said to be produced by the same weather system. The classification of an outbreak can vary depending on interpretation. It is said that in order to be classified as a “tornado outbreak” there must be a certain number of tornados that touch down. It is said that the US has the most tornados of any country. This can be attributed the location with in the mid latitude. The Rocky Mountains, have the ability to block moisture and “buckle” the atmospheric flow; thus forcing a lot of dry air at mid-levels of the troposphere, due to downslope winds. While the Rockies are forming a “dry-line” the Gulf of Mexico on the other hand contributes a lot of low level moisture. This mixture of warm air and cold air is to blame for the large number of tornados that form in the US. These events are most prevalent in the Midwestern and Southeastern United States, along with the Great Plains also known as (tornado alley) although some of these systems have been known to move as far North as Canada. The tornado outbreak that took place on the 17th of November is said to have been the one of the largest outbreaks to have occurred in eight years. This particular storm spawned a total of 72 tornados that swept through seven states, according to the National Weather Service. This outbreak is being considered the fourth largest outbreak of its kind, especially this time of year.
Low gray clouds loom in the distance. Suddenly, a tail descends from one of them, and twists itself into a spinning, funnel-shaped system - a tornado. It whips back and forth as it moves across the earth, whisking away houses, trees, and other objects with the tremendous force of its spinning winds. Tornadoes are one of the world’s deadliest and most unpredictable villains mankind will ever face. Tornadoes can harm and benefit society in many different ways. Tornadoes can harm society in destruction of property, mutilating the economy, traumatizing
A tornado requires some basic ingredients to come together. First, energy in the form of warm, moist air must exist to feed thunder storms. Second, there must be a top layer of hot, dry air called a cap. This air acts like a lid on a simmering pot, holding in the warm air that’s accumulating in the atmosphere below until the storm’s ready to burst. Last, there has to be rotating winds speeding in oppositedirections at two different levels in the atmosphere, a phenomenon called wind shear, can cause the storms to rotate. Tornado alley is perfectly situated to meet these requirements. (1)
In cases of extreme weather such as hurricanes, tornadoes, and tsunamis, the degree of accuracy is far more reliable. The Doppler Radar enables meteorologists to follow the pathways of hazardous weather conditions including tornadoes (particularly in America) and warn the inhabitants of a particular danger zone, which gives people a better chance of evacuating and more importantly surviving. In this sense accusing weather forecasting as being deficient is a misconception, yet predicting recent weather e.g. next day is often difficult due to sudden changes. One significant event that occurred in Southeast England was the October hurricane of 1987.
For a vortex of wind to be called a tornado, it must touch the ground. How is a tornado formed? Tornado formation follows several steps and involves different factors. It starts with large thunderstorms that happens in cumulonimbus cloud.
Tornadoes are one of the deadliest and most unpredictable villains mankind will ever face. There is no rhyme or reason, no rhythm to it’s madness. Tornados are one of the most terrifying natural events that occur, destroying homes and ending lives every year. April 29th, 1995, a calm, muggy, spring night I may never forget. Jason, a buddy I grew up with, just agreed to travel across state with me so we could visit a friend in Lubbock. Jason and I were admiring the beautiful blue bonnets, which traveled for miles like little blue birds flying close to the ground. The warm breeze brushed across the tips of the blue bonnets and allowed them to dance under the perfectly clear blue sky. In the distance, however, we could see darkness. A rumbling sky was quickly approaching.
1. According to the USA Today Tornado Information website, a tornado is a "violently rotating column of air in contact with the ground and pendant from a thunderstorm." Therefore, thunderstorms are the first step in the creation of a tornado.

Tornado safety and preparedness are key to protecting your loved ones during a tornado. So far, there has been no evidence that tornadoes pick up objects and move them to Oz, but we do know they can lift enormous objects and cause billions of dollars in damage.
