Tornadoes are created in many shapes and sizes, but they are typically in the form of a visible condensation funnel whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour (177 km/h); have length about 250 feet (76 m) across, and travel a few miles (several kilometers) before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour (483 km/h), stretch more than two miles (3.2 km) across, and stay on the ground for dozens of miles (more than 100 km) (Bluestein, 2013). A visible cloud is not needed for disbursing tornado. Some tornadoes may not appear to extend to the ground but are causing considerable damage (NOAA, 2014). Tornadoes can be occurred with various shapes and sizes, and most produce winds less than 120mph. …show more content…
Some tornadoes are very small and last for only a minute or so, while others can be a mile wider or larger staying on the ground for over an hour (NOAA, 2014). Tornadoes occur in many parts of the world, mainly USA, Australia, Europe, Africa, Asia, and South America. Even New Zealand experiences around 20 tornadoes each year. Two of the highest concentrations of tornadoes outside the U.S. are Argentina and Bangladesh (NOAA, 2014). The single F2 tornado that cut a narrow path across Atlanta in March 2008, for example, causing an estimated $340m of damage in less than 20 minutes (Maynard et al., 2013). After that tornadoes in United States resulted in the greatest loss of life since the 1920s. In many ways, the tornadoes of 2011 most resemble what happened in 1953. Unlike 1965 and 1974, there was not one day or even one outbreak that caused such a large percentage of the damage. Two outbreaks stand out, late April in the southeast most notably Alabama on April 27 where one tornado remained on the ground from Tuscaloosa to the suburbs
Meanwhile tornadoes are dramatically different from hurricanes. Hurricanes form over vast stretches of water, and the warmer the water the more the potentially deadly the hurricane will be. The Galveston Hurricane of 1900 ""¦was responsible for at least 8000 deaths" (Blake, et al, 2011). Hurricanes develop in tropical oceans and move westward in the direction of the southern and eastern United States. Tornadoes also affected by the jet stream form over land, not over water, and although they can be up to a mile wide, they are generally a quarter of a mile wide. Hurricanes are sometimes several hundred miles wide which makes them a far
Some tornado specifics can be interesting, some can be boring but these are the fascinating ones. There is a part of land in the Midwestern U.s where more than 1,000 tornadoes form. Most tornadoes only stay on the ground for less than five minutes and some tornadoes stand still while others can go on devastating speeds. The destruction tornadoes make is mostly from the debris that it picks up. More than half of tornadoes are weak and don’t cause many
Reasons why the Tri-State Tornado is Interesting. This tornado did seventeen million dollars of damage when it went through three states. The tornado was about one mile wide, had wind speeds of 300mph, traveled 219 miles, and traveled at a speed of 70mph average. It’s the deadliest tornado in America and second deadliest in the world. These are some pretty interesting things about a tornado and you don’t hear that all the
The month of April in 2011 holds the record of being the deadliest tornado series in the South, Midwest, and Northeast parts of the United States. Mississippi and Alabama was effected the most during this occurrence. A total of 320 deaths caused by tornadoes took place, including about 240 in Alabama alone. With four of the tornadoes measured to be EF5, Dr. Greg Forbes- Weather Channel’s current Severe Weather Expert- categorized this as a super outbreak.
My name is Rachel Lee. What is severe weather? Is a tornado a type of severe weather? If you want to know, it is yes. A tornado is a type of severe weather. A tornado is a violent, and narrow row of air that moves fast in a circular way, which comes from a thunderstorm to the earth. Tornadoes are recognized or known as cyclones. Cyclones can also be hurricanes, typhoons, or more. They are storms that counts as severe weather and move quickly around in a circular way. A tornado happens during a bad thunderstorm. Winds up high blow faster than winds down and lower. They both go in directions, which makes a circular motion. Then it starts to rotate faster and faster until it creates a tornado. Before the tornado hits, it dangles
To start the argument, we will begin with tornadoes. Tornadoes are generally located in the central part of the U.S. but can also touch the ground in other countries. According to Source 2, Central U.S.A. is mainly flat, allowing about 1,300 tornadoes hit this area of the U.S. per year and, because of this, about 500 million dollars is used to repair damage.
A tornado is a mixture between rising hot hair and falling cold air that causes a swirling column. It is first characterized by rotating air that looks like a funnel. As the funnel and storm develop, the funnel cloud drops down into a tornado that looks like a column. As the tornado picks up debris and dust its speed increases.
2011 contained one of the deadliest and costliest tornado seasons the United States has ever seen, leaving 550+ dead. In one year alone, 1,692 tornadoes touched-down, primary in the area known as “Tornadoes Alley” (extending from Texas to Minnesota). April had the highest amount of reported tornadoes for the year, totaling 875.
To continue, the two form in a different way. A tornado forms from a thunderstorm. The thunderstorm has to be very powerful. A hurricane forms from warm water oceans. On the contrast, a tornado is a rapidly rotating column of air. A hurricane is a combination of heavy rains, strong winds, and hug crashing waves (the waves can reach up to 70ft high.) According to meteorologist Spencer Adkins, he states that, "A tornado is just a few miles wide, while a hurricane can start at Miami, Florida and can go all the way to New York City!"
Finally for the funnel shape of the tornado to occur, the wind traveling towards the ground causes a rotation that generates a funnel cloud near the ground.Tornado alley is an area in the US where tornadoes spawn far more than anywhere else in the world. This area extends from North Dakota straight down to Texas. The main reason tornadoes occur here more than other places, is because topography in this central US area consists of open plains and fields. During summer the plains tend to get very hot and this warm air rises to meet with cool air creating conditions ideal for storms. Tornadoes usually last around ten minutes; larger and stronger tornadoes can linger up to thirty minutes. Wind speeds during tornadoes reach up to three hundred miles per hour, but most tornadoes can travel at speeds of around one hundred miles per hour. Tornadoes typically cover and span a few miles. The speeds they move are devastating and strong enough to rip houses out of their foundations. At least 60 people in the US are killed
The twister and hurricane varies in the frequency they come to the U.S. For starters, the tornado cost about $500 Million in damage a year. Also, anywhere between 1,200 to 1,300 tornados hit the us a year! On the contrary, the hurricane cost about $15 Billion a year. The good thing about hurricanes is only about five hurricanes make landfall a year in the U.S. Who knew hurricanes were so expensive! According to meteorologist Spencer Adkins, " 90% of a hurricane`s causalities are from
A tornado causes a lot of destructions! It can lift cars, level houses, and fling them 100 yards away! The deadliest outbreak came on April 3, 1974, when a two- day “Super Outbreak” of 147 tornadoes killed 308 people in 13 states.
Next, tornadoes are caused by thunderstorms, hurricanes, or other tropical storms, and they usually develop near the tail end of a storm. Usually, after the storm there is lots of damage done to the area that the tornado hit. In the text it says “ Tornadoes can appear from any direction, but most move from southwest to northeast.”
Whoa, my house just vanished. Hurricane and tornadoes can happen all over the world. Tornadoes and hurricanes can also be very dangerous. Tornadoes mostly happen on dry land where all the warm. Hurricanes and tornadoes come in many sizes, cost lots of money because of damages, and require you to take shelter.
A tornado is defined as a violently rotating column extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of two hundred and fifty miles per hour or more. Damage paths can be more than one mile wide and fifty miles long. In an average year, eight hundred tornadoes are reported nationwide, resulting in eighty deaths and over one thousand five hundred injuries. In the body of my essay, I will tell you about types of tornadoes, where tornadoes come from, where and when tornadoes occur, the damage they inflict, variations of tornadoes, and how to detect tornadoes.
