TRANSCRIPT

• Hurricanes are giant, spiraling tropical storms that can pack wind speeds of over 160 miles (257 kilometers.) Hurricanes begin as tropical disturbances in warm ocean waters with surface temperatures of at least 80 degrees Fahrenheit (26.5 degrees Celsius). These same tropical storms are known as cyclones in the northern Indian Ocean and Bay of Bengal, and as typhoons in the western Pacific Ocean.

• In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. Before thunderstorms develop, 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 thunderstorm updraft tilts the rotating air from horizontal to vertical.

• How do tornadoes work?

• Why are there tornadoes in the world?

• How do tornadoes form?

• Why do tornadoes suck things up

• A lower cloud base is formed in the area of the wind rotation, which is called a rotating wall cloud and it later expands to become a tornado. Along with tornadoes, hailstorms and strong winds blowing in one direction are also observed.

• Not all tornadoes formed are the same, and vary in terms of their impact and destruction they cause.

• These twisting storm columns can reach wind speeds of 318 mph (512 kp h) and measure miles across, scarring the Earth and decimating homes and buildings in the process. Yet, in some parts of th e world, these powerful storms are a regular occurrence. The United States alone experiences more than 1,000 tornadoes a year, and the storms have been reported on every continent except Antarctica [source:

A tornado is a violent, rotating column of air which

Is in contact with both the surface of the earth and cloud or rare cases, the base of the cloud. The intense of all atmospheric phenomena

• When things are in the tornadoes way, it sucks it up. It's kinda like you suck water threw a straw. But sometimes people get sucked in tornadoes. They'll be okay if the tornado lets them down. But that would mean falling from VERY high air. Try to stay safe.
