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.
Tornadoes are some of the most unpredictable weather we have on earth. Tornadoes belong to the category of meteorology in earth science. Meteorology is the science that deals with the weather and conditions. A tornado is a violent destructive whirling wind accompanied by a funnel-shaped cloud that progress in a narrow path over the land, (Merriam-Webster, 2014).
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.
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.
In this paper, I will discuss what tornadoes are and how they form, what different forms of tornadoes there are, what tornado watches and warning are and give examples of tornadoes in Oklahoma and what destruction they caused, also while providing information about the Doppler radar.
On May 20th, 2013 a EF 5 tornado hit Moore, Oklahoma and surrounding towns, with a path as wide as 1.3 miles wide (2.1 km) and had a wind speed, estimated at its peak, of 210 miles per hour (340 km/h). Killing 24 people, and injuring 377, this was one of the United States worst tornadoes in the past few years, along side the Joplin, Missouri tornado, in 2011. One of Mother Nature’s most dangerous and still very mysterious phenomenons averages about 1,200 reported each year, resulting in 80 deaths and injuring 1500. With very little known about them, especially whether or not they will form is one of the questions that plague meteorologist to this very day. What causes tornadoes, how does the tilt and gravity of the earth affect the winds to produce a tornado, and what will the future hold about our understanding of tornadoes?
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.
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.

Tornadoes are powerful and destructive phenomena created in strong thunderstorms. Tornadoes are most common in the United States, and in the U.S., they are common in an area called Tornado Alley. Every year, tornadoes wreak havoc on the countryside, towns, and even cities. The deadliest tornado in U.S. history crossed over three states, destroyed 15,000 homes, and killed almost 700 people. There are only a couple of people on record that claim to have been in and seen the center of a tornado and lived. Tornadoes even have their own rating scale, based on their wind and damage level.Tornadoes are powerful vortexes created in thunderstorms, are common in the U.S., have its own rating scale, have only been seen on the inside a few times, have the potential to demolish towns, and can take lives.
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.
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.
Most tornados produced from these storms are relatively weak, don’t enter inhabited areas, and cause little to no damage. The problem is that Oklahoma gets 55.1 tornados annually. With all of these tornados, a couple of them are bound to go through populated areas and cause damage. The damage the tornado causes incre...

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.
