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.
This outbreak covered an extensive amount of land; just to give an example there were t...

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.
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.

A tornado outbreak occurs when a large number (six or more) of tornadoes are formed in groups or individual storms within a 24-48-hour period over a specific geographical area and spawned from the same general weather system. The April 3-4 outbreak of 1974 was the worst in the United States recorded history. Never before had so many tornadoes brought so much destruction to such a wide area of this country. It was so bad that a name had to be found for it. "Super Outbreak" is what they came up with. This storm, which extended from the afternoon of April 3rd through the morning of April 4th, produced 148 tornadoes in thirteen states.
At sometime between 4:45 p.m. (Regina: The Early Years, 2014) to 5:00 p.m. (Saskatchewan Archives Board, 2011) local time on Dominion Day, June 30, 1912, a funnel cloud, and possibly a second funnel cloud which dissipated early on, touched down 18 km to the south of Regina, Saskatchewan, near 50.4547° N, 104.6067° W (see Figure 1), and travelled north along the ground (see Figure 2). The tornado, popularly called the Regina Cyclone, first cut through several farmlands, then Wascana Lake, before hitting downtown Regina (Heidorn, K.C., 2008), and continued to travel 12 km north past the city of Regina until it subsided (Saskatchewan Archives Board, 2011). The tornado was three blocks wide (Heidorn, K.C., 2008), and managed to demolish farms, residential areas, the downtown core, and the warehouse and railway districts (CBC, 2013). It traversed the city in about three minutes (Regina Public Library, 2007).

Characteristic calamities truly are very normal over the globe. There are of various types generally Earthquakes , Volcanic Eruptions and Snow storms. In light of the climatic conditions in my general vicinity Snow storms are inclined to be happened oftentimes. The primary Natural calamity in the whole Central America is a snow storm. Indeed there is a possibility of event of tremors. Anyway by watching the atmosphere from past decades there is a less risk of event of seismic tremors. Despite the fact that such seismic tremors happen the force that is recorded is low. Fortunately there are no volcanoes in the range. So there is no statement for the volcanic ejections to happen. Be that as it may there is an alternate debacle which is having an opportunity to happen is a Tornado. A few safeguards must be strictly utilized with a specific end goal to get maintained from these sorts of circumstances. All the individuals living in the specific group must be given legitimate directions on the sort of fiascos that are happened and the mind that ought to be taken while the event of such exceptionally risky episodes in the true worls.
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)
There has been an upward trend in storms causing financial losses, but there are also societal contributions to this trend, such as increases in population and wealth. Recently, scientists have also discovered that the number of tornadoes that occur in outbreaks is increasing by about 0.66 percent per year. Scientists are saying that, global warming could be cause of an increase in tornadoes and natural disasters. Fuel for storms is heat, and heat causes it causes more evaporation of water which is critical to generate
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.

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.
