TED-Ed: How do tornadoes form? - James Spann

The video introduces the concept of tornado chasing and provides insights into tornado formation. Tornadoes are rapidly rotating columns of air that form inside storms and connect with the ground via a funnel of cloud. They pose significant threats to life and property. The video explains that tornadoes begin with supercells, which are powerful thunderstorms. Specific conditions, such as rising air and moisture, are necessary for tornado formation. The development of a mesocyclone, a spinning air mass, is crucial. The video also describes the lifecycle of tornadoes, from formation to dissipation, and highlights the ongoing research and observation efforts by meteorologists and storm chasers.
