Tornado Formation and Safety Measures

Meteorologist Alex O'Brien discusses tornadoes, one of the most extreme weather events. The video covers how tornadoes form, the role of wind shear, and how to replicate a tornado at home using simple materials. It explains the different types of tornadoes, such as rope and wedge tornadoes, and introduces the Enhanced Fujita scale for measuring tornado intensity. The video emphasizes the importance of having a safety plan and being prepared for tornadoes, including identifying safe zones in your home and staying informed through emergency notifications.
