What is a tornado? Our textbook defines a tornado as a violently rotating column of air in contact with the ground that is usually produced by a thunderstorm. Tornados are something that we, as Midwesterners, have heard about our whole lives, and sometimes even grown up with. But there is much more to learn about tornados than just the movie Twister. Tornados have relation to Chapter 1: Monitoring the Weather, Chapter 8: Wind & Weather, and, of course, Chapter 11: Thunderstorms and Tornados. First, I would like to discuss with you the basic facts of tornados. As stated in the introduction, tornados are a violently rotating column of air in contact with the ground, and it is usually produced by a thunderstorm. According to our textbook, there …show more content…
This chapter obviously links together with this event because Chapter 11 is all about explaining tornados, what they are, their characteristics, what causes them, etc. The Tri-State tornado occurred before weather forecasters had the technology to predict, identify or track severe weather. When the thunderstorm formed over southeast Missouri early that afternoon, no one had any idea how severe it would get and that it even had the potential to turn into a tornado. In that time, the forecasters had no way of determining the strength of the storm or the devastation it was about to bring. When the tornado first developed a few miles northwest of Ellington, Missouri, it gave no signs or indications that it would grow into a monster and continue as it did. That tornado barreled across southeast Missouri, southern Illinois, and southwest Indiana at incredible speeds totaling 219 miles, and lasting 3.5 …show more content…
Tornados are rated on an EF scale, which depicts its level of severity. An EF-0 produces minor damage, snapping tree branches and possibly breaking some windows. An EF-1 or EF-2 can cause moderate to considerate property damage, and even have the potential to take lives. An EF-3 tornado can partially destroy well-constructed buildings and even lift motor vehicles from the ground. The violent end of the EF-scale, an EF-4 or 5, can be described as devastating or incredible. An EF-4 can level sturdy buildings and other large structures, and toss vehicles around like toys. An EF-5 can lift sturdy frame houses and transport them for a distance before they begin to disintegrate from wind gusts over 200 mph, or experiencing violent crashes. Because of its severity, strong winds, and lifespan, the Tri-State tornado was obviously categorized as an EF-5 tornado. Most tornados are formed from a weather system known as a supercell thunderstorm. In a supercell, the wind strengthens and veers (turns clockwise) with altitude. This shear in wind speed causes the air to rotate about the horizontal axis in a rolling motion. This rotation interacts with the updraft and the tube of rotating air is tilted from horizontal to vertical, creating the
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.
Storm Over Texas: The Annexation Controversy and The Road to Civil War, authored by Joel H. Silbey, presents the issues faced during the antebellum over the admission of Texas into the union. The partisan differences resulted in harsh controversy of the South and North, leading towards the Civil War. Silbey goes in depth of the situational occurrences with important figures such as John C. Calhoun, John Quincy Adams, James K. Polk, and Martin Van Buren. Not only does Silbey describe the movements during this time, but keying the main aspect of slavery which was the core issue, leading ultimately to Southern Secession and the Civil War.
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.
In the book Storm Over Texas, by Joel H. Silbey the critical controversy of North vs. South is displayed. The book goes into great detail of the wild moments leading into the Civil War, the political dysfunction that ran throughout Texas, and many reasons the American Civil War sparked up in the first place. This book truly captives great Texas history and has valid information and points of our states different point of views on history.
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.
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.
By late afternoon and early evening, storms began to blow up across parts of Oklahoma, Texas and Kansas. Although the storms began with only moderate and disorganized activity, they developed quickly into well-organized, explosive storms. As the day wore on, the National Weather Service and Storm Prediction Center began to issue more urgent updates to alert the public to the growing danger. Several storm chaser teams began to close in on the southern portion of Kansas, where conditions appeared most favorable for twister development.

B. Relevance: Illinois rests on the boundary of what tornado researchers call tornado alley. This is the area of the country that receives the most tornadoes every year. According to a 1995 brochure distributed by the National Oceanic and Atmospheric Administration (NOAA), Illinois averages 27 tornadoes a year. Also, nearly 5 people die every year in Illinois as a result of tornadoes [ AID]. In fact, according to Tornado Project Online!, a website hosted by a company that gathers tornado information for tornado re searchers, the deadliest tornado in U.S. recorded history occurred in Murphysboro, Illinois. In 1925 a violent tornado killed 234 people in this Southern Illinois town.
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.
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.
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.
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)
