Tornadoes

Submitted by heypunk28 on May 8, 2008

No one knows what mother nature is going to do the next day, she is so unpredictable. One of the most lethal parts of mother nature is the tornado. A tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees. Damage paths can be in excess of one mile wide to 50 miles long. In an average year, 1000 tornadoes are reported nationwide.
Its pretty simple how most tornadoes actually arise. Most tornadoes form from thunderstorms. All you need is a bit of warm air, usually coming from the Gulf of Mexico. And some cool, dry air most likely coming from the north like Canada for instance. When these two air masses meet, they create instability in the atmosphere. A change in wind direction and an increase in wind speed with increasing height creates an invisible, horizontal spinning effect in the lower atmosphere. Rising air within the updraft tilts the rotating air from horizontal to vertical. An area of rotation, 2-6 miles wide, now extends through much of the storm. Most strong and violent tornadoes form within this area of strong rotation. When you spin a bottle of water in circles, you can see a similar shape that looks like a tornado. The clouds above the tornado also spin slowly, almost making one feel amazed by the dark color of the clouds spinning around the vast column of death.
There are many different types of tornadoes, different color, size, and contents within the tornado. It depends on where the tornado is located that determines the color of the dangerous column of weather. When a tornado rises up in a field plain, it turns red usually because of the soil that is in the ground. If one appears in a particularly dry place, the tornado can be almost transparent without the debris...
