The Four Causes And Forms Of Tornadoes

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

In this paper, I will discuss what tornadoes are and how they form, what different forms of tornadoes there are, what tornado watches and warning are and give examples of tornadoes in Oklahoma and what destruction they caused, also while providing information about the Doppler radar.

4. Where do thunderstorms form most frequently in the US?  Why is this the case?  Is this also where most tornadoes occur?  Explain.

How tornadoes form you ask? Tornadoes form when different winds from different places met and form this giant spinning destructive cyclone which can be powerful or only cause minor damage. Tornadoes form when hot air from different places and cold air from different places collides which can make a tornado at any speed,

What is a tornado?A tornado is a narrow, violently rotating column of air that extends from the base of a thunderstorm to the ground. Because wind is invisible, it is hard to see a tornado unless it forms a condensation funnel made up of water droplets, dust and debris. Tornadoes are the most violent of all atmospheric storms.Where do tornadoes occur?Tornadoes occur in many parts of the world, including Australia, Europe, Africa, Asia, and South America. Even New Zealand reports about 20 tornadoes each year. Two of the highest concentrations of tornadoes outside the U.S. are Argentina and Bangladesh. How many tornadoes occur in the U.S. each year?About 1,200 tornadoes hit the U.S. yearly. Since official tornado records only date back to 1950,

We also learned In earth science class that tornadoes typically are more likely to form when the sky is covered with cumulonimbus or towering cumulus clouds. However, in the Twister movie, we learned that often times meteorologists as well as forecasters will use lifted index's to pin point a tornados whereabouts. Also in the Twister movie, we learned that tornados are often times formed from funnel clouds created by cumulonimbus or towering cumulus clouds. Another thing we learned from the Twister movie is that a water spout happens when tornados crosse over water and the water then begins the get sucked up into the tornados suck zones forming a water spout. In addition, in the movie Twister we also learned about Sister Tornados which typically spawn next to an already occurring tornado. Most Importantly, in both earth science class, and the movie Twister, we learned about the Fujita Scale which is a scale that classifies rating tornado intensity, based primarily on the damage tornados inflict on human-built structures and vegetation. The Fujita Scale if rated F1-F5 with F5 being the most strongest and most severe tornados,

The Joplin, Missouri Tornado included many details common to Tornadoes. All Tornadoes are created by a series of rotating air from thunderstorms. Once a lot a rotating air combines a funnel cloud starts to form from underneath

So the warm moist air creates clouds of rain and thunderstorm. Adding to that winds with different speed going in different directions assisting in expanding these great clouds of rain and thunderstorm. With

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 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.

Hurricanes and tornados are related in many ways. One such way is there appearance. According to Hammond, “A tornado can be described as cyclonic…” (Page 46, paragraph 1) Tornados are always cyclonic, yet in the Northern hemisphere they spin counterclockwise, and in the Southern hemisphere they rotate clockwise. This is very similar to hurricanes, as they move and rotate the same way. Another reason why hurricanes and tornados are similar is that they both cause a similar amount

Tornadoes can also occur in many other areas of the world as well. They have been recorded in Australia, Europe, Africa, Asia, and South America as well as in North America. They occur mostly during the spring and summer; however, the tornado season comes early in the south and later in the north because spring comes later in the year as one moves northward. They usually occur during the late afternoon and early evening. However, they have been know to occur in every state in the United States, on any day of the year, and at any hour.
