The Silence Before The Storm

Also there is an updraft of the lighter moist warm air from the ground, which keeps the thunderstorms from dissipating. While the warm air is rising there is cold dry air that is causing a downdraft causing the heavy water droplets to fall. The most violent storms are known as supercell storms, which are also the most likely to produce tornadoes. The last factor needed to produce the tornado is the jet stream to be moving at least 150 mph.

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.

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.

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,

A tornado in Oklahoma picked up a small herd of cattle and carried them across the countryside, then sat them down and the cattle were unharmed. Dust Devils are a type of tornado that passes through a desert area. There can be times when multiple tornados form at a time and then they travel in swarms just like fish. The most powerful tornadoes are from the United States. Every tornado has its own color, sound and shape that is just for itself, just like fingerprints, no tornado is exactly the same.

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.

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

The Joplin tornado was caused by a sandstorm that turn into a a lot of winds. Warm air from the Gulf of Mexico moved north until it faced cold air brought by the gasses from a jet stream. Most tornado happen in spring and summer that form really big thunderstorms to a tornado.Wind spins and forms into

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.

Tornadoes and hurricanes appear to be similar in their general structure. Both are characterized by extremely strong horizontal winds swirling around the center, strong upward motion dominating the circulation with some downward motion in the center. The tangential winds far exceed the radial inflow or the vertical motion, and can cause much damage. Hurricanes always rotate counterclockwise in the northern hemisphere (clockwise in the southern), the direction of their rotation being determined by the Earth's rotation. This is almost always true of tornadoes too, although on rare occasions "anticyclonic" tornadoes spinning in the opposite direction do occur (tornadic circulation is determined by the local winds).

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.

Tornados are an extremely interesting phenomenon. These natural disasters need a series of very precise activities to occur in order to materialize. For a tornado to form, it needs the same events as in a thunderstorm to occur. First a wind shear needs to take place; this is when two opposing gusts of wind on different levels make a horizontal vortex. One section of the vortex will rise because of the buoyant warm air, creating a storm. After this a supercell can form; a supercell happens when upper-level wind causes the storm to spin. The supercell can grow very large as long as warm air continues to be sucked through the vortex away from the cool air. In the picture to the left, the supercell is above the funnel like shape of the tornado.

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.
