Essay on Floods

Tornados are one of the most destructive and devastating natural forces on Earth. When a tornado is fully created, wind speeds can reach up to more than 300 mph (483 km/h). Most tornadoes that occur are between the Appalachians and Rocky Mountains, but tornados can happen where ever the conditions are right. 90% of tornadoes that happen in the United States, happens in the Central United States. Even though scientist have not yet understood how tornadoes are formed, they’ve developed a theory that consist of the process and conditions of which a tornado must have to form.

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. <Add thesis>

The first thing that starts a tornado would be the winds. The wind updraft can form a funnel. This funnel is called a Mesocyclone and when the mesocyclone touches the ground it is considered a tornado. Clouds play an important role in forming tornadoes too. Some other clouds are called, Wall Clouds. These clouds protrude from the sky and look like a giant waves coming down about to crash on earth. When wall clouds form the sky might turn to a greenish color or some other color. This wall-cloud

When tornadoes do form; such places as the National Weather Service (2014) classify tornadoes into three categories. These categories are weak, strong, and violent. “

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

Tornadoes and hurricanes are very destructive. Tornadoes are spinning columns of air that form from the the sky to the ground. Hurricanes are the most powerful storms on Earth. Hurricanes are tropical storms that travel across the Atlantic Ocean. Hurricanes happen when winds exceed to 75 miles per hour. Tornadoes have winds that can get to the speed of up to 200-300 miles per hour. There is a level 5 hurricane which means that the winds exceed up to 150 miles per hour.

The best predictors for tornado activity are rotating thunderstorms. They are well defined thunderstorms on a radar that include flash floods, hail, lightning, or severe winds. (“11 Facts About Tornadoes”) These storms are called supercells (“Tornado Facts”). Once they reach land, tropical storms or hurricanes can be accompanied by tornadoes. When a warm front meets a cold front, a thunderstorm can form, which can create 1 or more tornadoes (“11 Facts About Tornadoes”). With little to no warning, a tornado may strike.

A tornadoes form when it is humid but the ground is wet and slower winds are by the ground as the fastest wind are higher in the sky. Because of this the wind starts to circle around when the slow wind moves up higher. Rain will fall and so will a funnel which is the tornado. The reason twister in Florida left extreme damage and many houses were being fixed or covered with tarp. Today they are cleaning up the damage or debris all over town. Other places tornadoes have touched down resonantly are Virginia and North Carolina the worst one was the one in Carolina taking three lives. To not be one of those three you must find shelter once you hear the word "WARNING." if you hear "watch" then prepare to go into "WARNING." Pleas remember that.

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.

Every year we practice tornado drills for our safety. A tornado is a violent rotating column of air extending from a thunderstorm to the ground.They can destroy large buildings, trees and vehicles hundreds of yards. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide. Tornadoes form out of thunderstorms, where moist air rises, cools and condenses into clouds that release heat and force cooler air back down. If the updrafts are strong enough, the feedback loop forms an air vortex that continues to shunt more moist air upwards and eventually forms a tornado.

On the other hand, a tornado, which is a violently rotating winds with air column like a funnel shape, forms on land and extends downward from the cloud to the ground. The tornadoes form by the convergence of cold and warm air currents. The tornadoes are associated with heavy rain, large hail, strong cloud and ground lightning. Tornadoes have been found in all continents except Antarctica. A large number of tornadoes have been seen in US Midwest, such as Oklahoma, Missouri (Hurricane vs. Tornado) (Hurricanes: Science and Society:

A tornado is a very complex and complicated type of outdoor vacuum. The various types of tornadoes are caused when a great size of particles become part of cloud and start releasing heat rapidly which makes it rise and create a vacuum underneath it. The air that quickly goes into the vacuum creates the center of the tornado or the tornadoes vortex. Then when the air temperature changes it causes a sudden drop in the air pressure. When the heat is being released in the vacuum it causes precipitation. The rain released is equal to the amount of heat absorbed.

The strongest tornadoes come from the kind of long-lasting fierce thunderstorms known as supercells. As the name implies, these are intense thunderstorms, which can produce large hail and downbursts in addition to tornadoes. Supercells are most common on the Plains in the Southeast and across the Midwest, but do occur elsewhere.

While natural disasters such as floods, drought and hurricanes are commonly thought to occur due to environmental forces such as weather, climate and tectonic movements; a deeper investigation into the ‘disaster’ displays other contributing forces. Human factors have a large, if not equal, contribution to the occurrance and outcome of such disasters (Pelling, 2001). As Pelling (2001) argues, there is both a physical and human dimension to ‘natural disasters’. The extent to which the natural occurrence of a physical process, such as a flood or earthquake, impacts on society is constructed by that society, creating a ‘disaster’ as measured by a

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.
