Tornadoes form from thunderstorms where warm moist air and cool dry air masses meet to create an instability in the atmosphere
High pressure air and low pressure air combine and that new air becomes warm and moist and rises the surrounding air starts to swirl around it
Once formed, hurricanes take energy from the warm ocean water to become stronger. A storm will strengthen if there is a supply of warm, moist air to feed it. Warm, moist air is found above warm, tropical ocean waters.
Hurricanes form over warm water while tornadoes form over land within storms
Hurricanes wind speeds are usually less than 180 mph while a tornadoes wind speed can be up to 300 mph
The Tornado Alley starts from central Texas, goes north through Oklahoma, central Kansas and Nebraska, and eastern South Dakota.
Hurricanes cause erosion, buildings getting destroyed, heavy flooding, loss of power and contaminated water supply.
Hazardous or toxic material could be carried and transported along down streams. Tornadoes also could transport organisms across the land while destroying top soil and crops.
Tropical Storms are an upgrade into a tropical storm occurs when cyclonic circulation becomes more organized and maximum sustained winds gust consistently
Tropical Depression is when a low pressure area is accompanied by thunderstorms that produce a circular wind flow with maximum sustained winds
A hurricane is when A tropical storm is upgraded into Category 1 hurricane status as maximum sustained winds
