Oklahoma Tornadoes and Their Destructive Ways
What makes tornadoes and their destruction interesting to people? Is it the variety in formations, the miles one can travel, the random paths it takes, the changes tornadoes can make on climate and the formation of the land or is it because tornadoes often leave behind a path of destruction and deaths?
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.
The questions often asked is; what are tornadoes and how do they form?
Tornadoes are “violent windstorms that take the form of a rotating column of air or vortex that extends downward from a cumulonimbus cloud” as Tarbuck and Lutgens (2012) explain.
Tornadoes form from wind shears. Wind shears form from warm air that is found at ground level; when it’s raised, the updraft meets a down draft of cooler air that is moved in the opposite direction of the warm air. When both are pushed towards the Earth, this creates wind shear. A spinning tube of air, created from wind shear; tilts upward into a vertical position, as the updraft sucks up moisture from the ground and into the sky. As the warm air cools high in the sky; this produces condensation. The condensation then produces thunderclouds, which rise to 30,000+ feet. The spinning formations of air are then trapped and lifted into the thundercloud. This begins as swirling motion and as continued (if the winds remained viable), a supercell will form. Mesocyclones as they are known are a rotating cloud. If these rotating clouds run into humid air it will spi...

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.
I have chosen the scene when the tornado actually hits during this scene there are two main characters Dexter and famous storm chaser Dr. Norman Gage. Dexter is eleven years old and loves to study the weather he says when he grows up he wants to be a storm chaser just like Dr. Norman Gage. The other main character is Dr. Norman Gage he has his own T.V. series showing him chase storms but in the scene he makes a terrible mistake of getting out of his car and trying to get some good footage of the tornado and gets swept away. Dexter’s mom and dad allowed him to go storm chasing while they left the town.
In the article by Jeff Piotrowski and the article on the Joplin Tornado: Evil Swirling Darkness, explains that the Joplin tornado took out the city of Joplin, Missouri. The tornado came into the town of Joplin on May 22, 2011 and was about a mile wide. Fires were attacking the city and homes from broken gas lines, and many people were buried alive in their houses. The fire department was gone and no one could find any police to help. Neighbors helped neighbors, pulling each other out of the ruble. Over 125 people had died all from being trapped and suffocated, to be cut open by sharp objects that fell. In the end many people had died and were injured during the tragic tornado that came through and left Joplin in horror and terror.
On May 22nd, 2011 a massive tornado hit Joplin, Missouri killing 162 people and injuring 1150. With wind speeds of 322km/h, the tornado made a total cost of over $2 billion for the city. 8000 structures were destroyed, 2000 of which were homes. Many people were left homeless. The tornado held an incredible EF5 rating on the Fujita scale, measured from the amount of destruction. The tragic event lasted 38 minutes, from 5:34 pm to 6:12pm. Cool wind from the Rockies in Canada and warm wind from the gulf of Mexico formed into a supercell thunderstorm creating a tornado in Kansas. The tornado rapidly moved into Joplin and continued on its 35 km path.
A tornado struck Joplin, Missouri on May 22, 2011 at around 5:40 pm. With a population around 50,559, it killed 161 people and injured approximately 1,100 people. The cost was an estimated $2.8 billion in damage. The American taxpayers had to give about $500 million in recovery money. This made it the deadliest tornado since 1950, which was when modern recordkeeping began. Since it was an EF5 tornado, it destroyed everything in its path. The city was ruined with only piles of debris left. It was a half-mile wide when it hit Joplin and grew to three-quarters of a mile wide. It destroyed nearly 7,000 homes in Joplin and damaged hundreds more. It covered over 1,800 acres of land. The warnings that the Joplin residents received were through three different ways. The tornado warning that was sent out for Joplin’s county was from Jasper County Emergency Operations Center (JCEOC) and they claim that the first siren went off at 5:11 pm. Two other warnings for the Joplin residents was they saw the tornado heading their direction, and the media coverage which was all local electronic media switched to wall-to-wall coverage seeing live footage of the tornado.
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.
On May 11, 1953 in the town of Lorena Mclennan County in Central Texas this deadly disaster strikes and damage very thing in its path. This intense spinning of a tornado is partly the result of the updrafts and downdrafts in the thunderstorm interacting with the windshirt.

It seems like every year Oklahoma is hit by massive storms and tornados that kill people and wound many others. Although some may say Oklahomans are used to getting hit by storms and tornados, but the outcome is never something we get used to and this year, just like any other, we got hit. On May 20, 2013 an EF5 tornado started to develop and little did we know that this tornado would be talked about everywhere. This tornado did major damage to houses, towns, and buildings, but what got this tornado so much attention was that it tore through an elementary school, that was unprotected from tornados, and killed seven children. According to the National Weather Service’s Top Ten Deadliest Oklahoma Tornados (1882-Present) this specific tornado is ranked number nine, killing 23 individuals and injuring 237 others. Even though there is a slim chance we could have saved everyone, we still could have saved those children in the Plaza Towers Elementary school. All they needed was a storm shelter at their school to take cover in and they probably would have all survived.
The belief that firing a cannonball or other projectile into a spout can "break it up" has no scientific foundation. Whirlwinds In the general sense, a whirlwind is any rotating mass of air or atmospheric vortex. The term is, however, commonly restricted to atmospheric systems smaller than a tornado but larger than eddies of micro scale turbulence. A whirlwind is usually named after the visible phenomenon associated with it; thus there are dust whirls, or dust devils; sand whirls, or sand pillars; and fire, smoke, and even snow whirls, or spouts. In contrast to the pendant form of the tornado funnel, a dust or sand devil develops from the ground upward, usually under hot, clear-sky conditions. The whirl shape is normally that of a cylindrical column or an inverted cone. The axis of rotation is usually vertical, but it may be inclined. The direction of rotation may be either clockwise or counterclockwise.
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).
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...
Tornadoes are commonly spawned in thunderstorms. The most creative tornado nurseries are the county-size thunderstorms called “supercells.” Thunderstorms evolve through three phases. During the first “cumulus” stage, a warm bubble of air is lifted upward. The lifting can begin when air flows up the side of a mountain or hitches a ride f...
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.
D. Thesis: In order to better understand tornadoes, it is important to explore what causes tornadoes to develop, how researchers classify types of tornadoes, and odd occurrences that may be associated with tornadoes.
