Recommended: Tornado formation and structure
Tornado: A destructive vortex that has a funnel shape cloud beneath a large storm system. In my opinion tornadoes are pretty scary and can be devastating to people’s families and their home’s. The first thing you should do when you hear a tornado is coming is go to the lowest level in your house thus, you will be safe. I have never been in a tornado before and I don’t plan to. Are you ready to learn how a tornado is formed and what the steps in doing it are? There aren’t many necessary conditions needed to from a tornado. The main requirement is to have intense heat. The reason this is needed is so the sun can increase its temperature and moist air will rise from the ground. Another condition is that a warm front and a cold front meet up. The reason for this is so the cold air can trap the warm air which will eventually cause a funnel to form. Another thing you will need is an increase in wind speed and change in wind direction. The reason you need this is because this will contribute to the rotation. These are all the necessary conditions you will need for a tornadoes to form. …show more content…
Do you want to know them? I am going to give you the four step explanation to how a tornado forms. First, Warm air is lifted by a front causing clouds and precipitation which will eventually lead to a thunderstorm. Next, under the storm, winds with different speeds form tubes of rotating air. Then, when the tubes go into the body of the updraft, it becomes vertical and the storm starts to rotate. This begins the formation of a supercell. Finally, the spinning tube is stretch causing the supercell to act as it is a vacuum. Instead of the vacuum sucking up dirt, it is sucking up air. After this the air acts to balance the pressure which forms a
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.
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...
In 2008 Hurricane Ike made land fall to the east coast line in Galveston Texas. The storm surge water that Ike produced flooded the east coast region of Houston and Galveston. It has been estimated over billions of dollars in damage to home owners, business owners, and cause numerus of deaths. The mass destruction that Ike caused had people coming up ways to prevent or lessen the effects if a storm like this would ever occur in the future. A storm surge project was drafted and submitted to politicians is being delayed due to funding issues. Money should not be the major delay when it comes to saving homeowners, business owners, and a life of a person.
In literature, symbolism is used to give meaning to certain things throughout a story that are different than their literal sense. Symbolism also gives the writer freedom to add a deeper meaning to their work. The storm that took place in Kate Chopin’s story, The Storm, is used to symbolize getting Alcee and Calixta back together, the passion between the two of them, and to keep Bobinot and Bibi from returning to the gallery to find Alcee and Calixta.

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.
A tornado occurs in very powerful thunderstorms, and usually it occurs in a super cell. A super cell is a type of storm that already has rotation inside of it, called a mesocycle. A tornado begins to form when a downdraft of air pulls the mesocycle down towards the ground. A funnel begins to form, and when the funnel cloud finally touches down, it officially becomes a tornado. As warm, moist air (the fuel of a tornado) is drawn into the tornado, it matures...
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)
Compare how the novels, 'To Kill a Mockingbird' by Harper Lee and 'The Colour Purple' by Alice Walker, use literary techniques to explore the idea of racial injustice and female empowerment. In today's society, despite progress in the civil rights and gender equality movements, there is still a significant amount of concern about both cases. Achieving a future free from racism and inequality requires large amounts of effort, commitment, and empathy to create social justice. This can include implementing policies and practices that promote inclusivity, and raising awareness which promotes equality for all.
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.
Hurricanes originate as tropical disturbances over warm oceans with trade winds. The tropical turbances intensify into tropical depressions, and eventually into a tropical storm. They only originate in the tropical trade winds because the ocean temperatures are quite warm there. Powered from the heat that the sea gives off, they are steered by the east trade winds and the temperate west ones, as well as by their own ferocious energy. Around their core, winds grow with a tremendous amount of velocity creating violent seas. As they move toward the shore, they move the ocean inward, while spawning tornadoes and producing torrential rains and floods.
A tropical cyclone is a warm-core, low-pressure system producing high winds that spiral counter-clockwise (in the northern hemisphere) and inward, with the highest winds near the center of circulation. The large counter-clockwise and inward flow is characteristic of the nearly symmetric structure of tropical cyclones as they are comprised of rain bands spiraling toward the center. These warm-core storms typically form over the tropical and subtropical oceans and extract their energy from the heat content of the oceans.
