Our final section in our text book talks about storms and weather forecasting. For our final assignment on weather, we are going to the computer lab to learn about tornadoes and hurricanes.
Tornadoes form from severe thunderstorms in a cumulonimbus cloud. When warm, moist air rises upward and meets colder, dryer air, the air begins to spin in all directions. If the wind staggers in just the right manner with sufficient speed, they will act on the upward rising air, causing a horizontal spinning effect in the lower troposphere. Once the moving air reaches the lowest part of the atmosphere, it is called a tornado. A tornado’s wind speed can move anywhere from 40-300 miles per hour. Tornadoes can develop almost anywhere in the world but are most commonly found in the Unites States.
Hurricanes, on the other hand, usually have slower wind speeds but can be just as deadly. Hurricanes must form over warm, moist water. Remember the remnants of hurricane Ike that reaches Burg last September? Imagine wind speeds twice as fast, a tremendous amount of rainfall and flooding almost up to your house. Unlike tornadoes, which last minutes to a few hours, hurricanes can last from days to weeks. Hurricanes move in a counter-clockwise direction around an “eye”.
The eye is the center of the storm and is the most calm. Don’t let this calmness comfort you. The outer part of the eye has the fastest wind speeds. These high winds do not cause most damage and casualties during hurricanes. Strong winds over the ocean can cause extremely large waves of water called storm surges. These storm surges create rapid movement of water over the land and flood the entire area.
