Tornadoes and the Fujita Scale

The video discusses the destructive power of tornadoes, focusing on an F4 tornado that hit a small town. It explains how tornadoes are rated using the Fujita scale, which assesses damage to estimate wind speeds. The video also explores how some buildings are destroyed while others are spared, often due to smaller vortices within the tornado. Technological advancements like Doppler radar have improved tornado forecasting, reducing casualties by allowing for timely warnings.
