tornadoes vs hurricanes

By Paul Reid

facts:



Tornadoes: A tornado is a violently rotating column of air that is in contact with the surface of the earth and a cumulonimbus cloud or, in rare cases a cumulus clouds. Tornadoes come in many shapes and sizes, but they are typically in the form of a visible condensation funnel, whose narrow end touches the earth and is often encircled by a cloud of debris and dust. Most tornadoes have wind speeds less than 110 miles per hour are about 250 feet across, and travel a few miles before dissipating. The most extreme tornadoes can attain wind speeds of more than 300 miles per hour, stretch more than 2 miles across, and stay on the ground for dozens of miles. Various types of tornadoes include the landspout, multiple vortex tornado, and waterspout. Waterspouts are characterized by a spiraling funnel-shaped wind current, connecting to a large cumulus or cumulonimbus cloud.

Hurricanes: Hurricanes are the most destructive natural weather occurrences on earth. Hurricanes have male and female names, but at one point only female names were used. Most hurricanes rage harmlessly in the sea. Did you know australians call hurricanes, willy-willies. Hurricane season in the atlantic runs from June 1 to November 30. Hurricanes usually form in tropical areas. Hurricanes can cause billions of dollars worth of property damage every year to man-made fixtures as well as to natural surroundings such as trees and shruberry. These storms can also change an area’s landscape; resulting in hills, road and trails to wash away.

How are they made:

Tornadoes are made by the updrafts and downdrafts in the thunderstorm (caused by the unstable air) interacting with the wind shear, resulting in a titling of the wind shear to form and upright tornado vortex.

Hurricanes begin as a tropical storms over the moist waters of the atlantic ocean near the equator. As the moisture evaporates it rises until enormous amounts of heated moist air are twisted high in the atmosphere.

Why are hurricanes so much bigger than tornadoes  

The evaporation in the water makes these storms so big. Thats probably why they start in tropical places because there is usually a lot of evaporation there.Why are hurricanes much bigger than tornadoes?
