How Tornados Are Formed

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.

A low pressure system was over Northwest Arkansas and Southwest Missouri moving towards the northeast. To the east of the low pressure system there was a warm front advancing north and a cold front trailing to the southwest. The temperatures recorded just before 1 p.m. was over 60o F. We can assume there was a 100-knot upper-level jet max moving from the west/southwest given the speed of the tornado. Wind shear was also present, helping with the rotation (National Weather Service, 2011). With these factors there was everything to make the perfect tornado.

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.

They are known as convective storms. Cell thunderstorms form in regions where limited vertical wind shear is present. The winds direction or speeds do not abruptly change rapidly. Ordinary storms develop and mature through a cycle, as cell thunderstorms don’t have this development. Different conditions vary from warm air rising, random turbulent eddies and terrain. These are a few that can be a trigger to these more impactful storms.

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,

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,

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.

The cause of Tornadoes are hot temperatures, cold temperatures, and humidity all coming together. The warm air rises, but at the same time the two fronts are meeting, the cold air barricades the warm air beneath it. The warm air is trapped below

Tornadoes may tend to be short, but they can destroy lots of stuff in that time. A tornado is a type of severe weather in which a dark funnel of strong winds spiral upward. The moment the funnel hits the ground, it’s officially a tornado. We don’t yet completely understand how tornadoes form. But we do know that the deadliest tornadoes are formed from supercells.

Most tornadoes come from thunderstorms. You need warm moist air and warm dry air. When the two airs mix it causes a tornado. Changes in the wind direction will cause the tornado to speed up.

Tornadoes form because of the interaction between the updraft and horizontal wind. Wind is “air

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

There are many types of tornadoes. The average tornado is usually split up into categories based on the
