The strongest winds on this planet occur inside the tornadoes. Not all whirlpools in the
atmosphere are tornadoes. A funnel cloud that
drops for a period of time out of the clouds overhead,
or a “dust devil” pirouetting across desert
sands under clear skies, are not tornadoes. The definition of a tornado
involves a vortex extending from
a thunderstorm and touching the ground.
Tornadoes are a very destructive piece of natural disasters that cannot be prevented and can often come with little to no warning to take shelter. Every year there are hundreds if not thousands of people that are affected by tornadoes and their aftermath. These deadly forces of nature come through areas with their damaging winds and can potentially wipe out houses off their foundation, destroy power lines, damage buildings, leave survivors with PTSD and ultimately even kill people.
Imagine being in a storm with 200 MPH winds and lots of rain, well you are in a hurricane. Hurricanes are one of the most powerful storms that can occur. Hurricanes are formed through specific months due to the temperature. They could last for various time periods. These storms are known for all the destruction they cause. There are two hurricanes that are greatly known for the path of destruction they left.
A hurricane is easily the most powerful storm that mother-nature can throw at us. Every year people who live on the coasts fight hurricanes with no dismay. A hurricane is simply too strong. Their winds reach speeds of 75 mph. The winds around the eye wall can reach 130 to 150 mph. They are 200 to 300 miles in diameter. The number of casualties is endless, as well as the widespread destruction that takes millions of dollars to repair. Even if the hurricane doesn’t cause a lot of damage, the storm surge will. Storm surge is the great tidal waves that crash into our coasts and make huge floods that are caused by hurricanes.
There are two differences between Tornado and Hurricane and a similarity between both of them. The similarity, both of them are strong winds than can make a big disaster. Cited from http://www.hurricanescience.org/society/impacts/tornadoes/, there are the differences between Tornado and Hurricane. The first different is about where they form. Hurricanes from over warm water in the tropical oceans and develop best when far from the jet stream, but, Tornadoes form over land and form within storms that are often very close to the jet stream. The last different is about how strong the winds are. Hurricanes usually less than 180 mph, but, Tornadoes can be up to 300
Tornadoes are powerful and destructive phenomena created in strong thunderstorms. Tornadoes are most common in the United States, and in the U.S., they are common in an area called Tornado Alley. Every year, tornadoes wreak havoc on the countryside, towns, and even cities. The deadliest tornado in U.S. history crossed over three states, destroyed 15,000 homes, and killed almost 700 people. There are only a couple of people on record that claim to have been in and seen the center of a tornado and lived. Tornadoes even have their own rating scale, based on their wind and damage level.Tornadoes are powerful vortexes created in thunderstorms, are common in the U.S., have its own rating scale, have only been seen on the inside a few times, have the potential to demolish towns, and can take lives.
Tornadoes are very dangerous phenomena?s. They have very high wind speeds and are rapid moving. Even though the very high wind speeds are dangerous, they are not the leading causes of death in tornado cases. They contribute to it though, the leading cause of death is people being struck with flying debris. Tornadoes can pick up trees, refrigerators, animals, automobiles, and even in one case an 88-ton train coach. Most people die due to head injuries where they have been struck with a rock or something of this sort.
According to Ahrens (2009), a tornado is defined as, “A rapidly spinning column of air that blows around a small area of intense low pressure coming from the base of a thunderstorm to the earth’s surface” (p. 394). Tornadoes can form in one of two ways either through a supercell thunderstorm or through a nonsupercell thunderstorm (Ahrens, 2009). A supercell thunderstorm forms when the ground grows warmer in spring and summer and the air further above the ground is cold (Ahrens, 2009). Warm air near the surface rises, as it cools the water vapor it carries condenses forming cumulus clouds and eventually form into cumulonimbus clouds (Ahrens, 2009). Winds near the surface blow in one direction while the winds further up blow in another; the difference creates a horizontally rotating mass of air (Ahrens, 2009). Rising warm air pushes the horizontally rotating air upright therefore, creating a mesocyclone which usually extends 2-6 miles in width (Nation Severe Storms Laboratory [NSSL], 1992). These rotating updrafts define a supercell thunderstorm and set the stage for possible tornadoes (Ahrens, 2009).
Hurricanes, also known as cyclones or typhoons, are huge, devastating tropical storms that can be up to 600 miles wide. They have strong, forceful winds that spiral inward and upward circling around the “eye” of the storm. Inside the eye, there are clear skies and light winds, however, surrounding the eye wall there are bands of wind and rain that spread out for over hundreds or thousands of miles. Hurricanes begin as tropical disturbances over warm ocean water (27°c or 80°F) and gathers heat and energy as it moves across the ocean. As evaporation from the ocean water increases its power, it changes into a tropical depression (wind speeds of less than 38 mph), then tropical storm (wind speeds of 39-73 mph) to finally a hurricane (wind speeds greater than 75mph). Hurricanes can last two weeks or more over open water and moves about 10-20 miles per hour. The safety of millions of people depends on the meteorologists and their ability to track these storms. Hurricanes may not be dangerous over open water, but are devastating when they hit land. They can cause torrential rains, high winds and storm surges as well as tornadoes, flash floods and land slides. Without warning of these hurricanes approaching, millions could die. The most effective tools meteorologists use are satellite images, radar and aircraft reconnaissance to study and warn people of approaching hurricanes.
A tropical cyclone is a warm-core, low-pressure system producing high winds that spiral counter-clockwise (in the northern hemisphere) and inward, with the highest winds near the center of circulation. The large counter-clockwise and inward flow is characteristic of the nearly symmetric structure of tropical cyclones as they are comprised of rain bands spiraling toward the center. These warm-core storms typically form over the tropical and subtropical oceans and extract their energy from the heat content of the oceans.
