How Tornadoes Form

The video tutorial discusses tornadoes, their formation, and characteristics. It explains the relationship between tornadoes and supercell thunderstorms, detailing the process from mesocyclone formation to tornado dissipation. The video also covers the Fujita and Enhanced Fujita scales used to measure tornado strength based on wind speed and damage. Finally, it provides safety measures and preventive steps to take in tornado-prone areas, emphasizing the importance of seeking shelter and using weather prediction models.

What is a tornado primarily characterized by?

• A rotating air column only in the sky

• A non-rotating air column

• A rotating air column in contact with the ground and a cloud base

• A stationary air column

Which atmospheric phenomenon is closely associated with the formation of tornadoes?

• Blizzards

• Supercell thunderstorms

• Monsoons

• Hurricanes

What does the Fujita scale measure?

• The color of tornadoes

• The temperature of tornadoes

• The duration of tornadoes

• The strength of tornadoes based on wind speed and damage

What is the wind speed range for an EF3 tornado on the Enhanced Fujita Scale?

• 136 to 165 miles per hour

• 111 to 135 miles per hour

• 65 to 85 miles per hour

• 166 to 200 miles per hour

What is a recommended safety measure if you are caught in a tornado without shelter?

• Go low in a ditch

• Stay in your car

• Seek shelter under a highway overpass

• Stand under a tree
