Whirlwinds are powerful and destructive atmospheric phenomena that can cause significant damage. They are made up of rotating columns of air, often accompanied by strong winds and heavy rain. VORTEXES, also known as cyclones or twisters, are the most intense type of whirlwinds, with wind speeds reaching up to 300 miles per hour. Oes are smaller whirlwinds that form in the wake of a larger vortex. Tornados are another type of whirlwind, characterized by a funnel-shaped cloud that touches the ground. All three of these phenomena are classified as whirlwinds.
