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
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.
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.
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.
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.
What is a tornado? A tornado is “a rapidly rotating vortex or funnel of air extending groundward from a cumulonimbus cloud.” (Haddow et al) Tornadoes produce destructive winds that can destroy everything that comes in its path. Meteorologists use the speed of the winds to classify the strength of tornadoes on the Fujita-Pearson scale. The weakest tornadoes, F0, have wind speeds from 65-85 miles per hour, all the way to an F5 tornado, with winds in excess of 200 miles per hour.
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.

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.

A tornado is a type of vortex. A vortex is essentially a rotating funnel that occurs from downdrafts that pull a medium, such as air or water, downward. Tornadoes are vortexes, and vortexes happen in day to day life, even if you don’t live in Tornado Alley. An everyday example of a vortex is when you pull the drain of a bathtub or sink and a rotating whirlpool occurs. This is a vortex. Tornadoes occur under this same principle, but with air in thunderstorms instead of water in a bathtub.
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)
For a hurricane to form, the ocean temperature must be warmer than twenty-six degrees Celsius, or eighty degrees Fahrenheit. Also, the air near the oceans surface must be filled with moisture. The seawater that is warmed by the heat from the sun evaporates to form vast storm clouds. As the warm air rises, the cooler air replaces it thus creating a wind. The rotation of the earth bends the wind inward causing it to rotate and spiral upward with a great amount of force. Around the Equator, the spin is the fastest. There, it can be faster than six hundred miles per hour.
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.
