Tornadoes may not be the first hazard that is thought of when you think of Eastern North Carolina, but they do happen here fairly often. The National Oceanic & Atmospheric Administration defines a tornado as “a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground.” (NOAA) Tornadoes can catch people off guard and lead to severe injuries or death. Tornadoes can range from mild to extremely violent. They occur in many parts of the world and the United States. Almost any adult is aware of what and where Tornado Alley is. For those that are not aware, it is an area of the central United States that has a very high amount of tornadoes that occur each year. This area runs from the most northern state to the most southern state and is several states wide. It is estimated that roughly 1,200 tornadoes occur each year that are documented. They may occur at any time of the day or night. Spring and summer see the most tornadoes but they may happen in other seasons also.
It is also important for emergency managers to educate their community on the difference between the two. A tornado watch means that conditions are favorable for tornadoes to occur. It also means to be on the lookout for severe weather and keep close to weather information sources. But a tornado warning means that a tornado has been indicated by radar or seen by spotters in the area of the warning. It also means that there is a serious threat to people’s lives and property in the affected area. Lastly, it means that you should stay inside a safe place or seek shelter and follow tornado safety guidelines. Wind speeds in a tornado can range from 40 mph to 320
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.
It is indeed sad that some people have to pay the price of criminals. However, when we see it from another perspective we might understand the reasons that may support it. The tragically events of 9/11 have change many things, in particular the safety of our people and policies of national security, as for instance the Anti-terrorism Act. The US government claims that this act is supported by several claims: one, this law is necessary to fulfill international obligations; two, many allied countries had ratified similar laws. And third, this Act provides greater protection than other legislations, (Boccabella, 2003). These legislations are not passed overnight, but after much study and critical thinking of possible consequences. What does not
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.

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.
What are terrorist attacks? Terrorist attacks are unexpecting attacks using violence against innocent people. Terrorists Cause harm to others in a cruel manner or kill people in cold blood giving them no mercy or feeling no pity for people who sit hopelessly begging for their lives.Terrorists also destroy many infrastructures or civilian population to prove they are high in political and social strength. Terrorists attack people to attain political or religious aims.
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.
Tornadoes are devastating atmospheric events that affect the ecology and the lives of people in their paths. Tornadoes are defined as “a violently rotating column of air, in contact with the ground, either pendant from a cumuliform cloud or underneath a cumuliform cloud, and often (but not always) visible as a funnel cloud” (Glossary of Meterology, 2011). The Tri-state tornado was the most deadly tornado in the United States. It stayed on the ground for a total of 219 miles through areas of Missouri, Illinois, and Indiana, killed a total of 695 people, and an estimated $16.5 million in damages (National Weather Service, 2011). Luckily, the tornado’s path was largely rural farmland with scattered small towns between them.
Evolution is a theory that is refuted by the majority of creationists; creationists argue that evolution is simply a “theory” and is not supported by scientific evidence. This argument is clearly false. In order for a scientific theory to become widely accepted by the majority of the scientific world, it must be supported with facts and evidence. In a recent Gallup Poll, 55% of scientists, a majority, believed in evolution with no divine intervention. An additional 40% of scientists believed in evolution with divine intervention; only 5% of scientists believe that the earth was created by a divine power in the last 10,000 years. However, the public opinion is nearly the direct opposite. 46% of those polled believed the earth was created by a divine power in the last 10,000 years; furthermore, 40% of those polled believe in evolution with divine intervention. Only 9% of those polled believed in evolution with no divine aid. The disparity between scientists and the public is too great to be ignored; despite the overwhelmingly scientific evidence, many people still do not fully support, or believe in the theory of evolution. There is also a clear correlation between belief in evolution and belief in God. While the polls attempting to record the religious beliefs of scientists are not always reliable, it is true that the percent of scientists that believe in the divine is much lower than that of the general public. According to the Eastern religions, such as Buddhism and Hinduism, these tensions between science and religion are only a Western issue, referring to the Abrahamic religions, Christianity, Judaism, and Islam. Many people, including scientists, believe that the relationship between science and religion should not...
Kansas City, Missouri is located on the border of the "Tornado Alley", an area where cooler air from the Rocky Mountains intermeshes with warm air from the Gulf of Mexico. This forms powerful storms especially during the spring and fall. Only some areas of the Kansas City Metropolitan Area have had some severe occurrences of tornadoes. This same region can also be subject to intermittent ice and snow storms during the winter months.
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 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)
middle of paper ... ... Help people if they are trapped under fallen debris and give them first aid in the event that they are injured. Tornado safety and preparedness are key to protecting your loved ones during a tornado. So far, there has been no evidence that tornadoes pick up objects and move them to Oz, but we do know they can lift enormous objects and cause billions of dollars in damage.
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.
