TORNADO

Tornado Try It Put your hand inside the spinning column of air and feel its motion. What’s Going On? A fan at the top of this exhibit pulls up the water vapor from its base. The air blowing from the holes in the black tubes causes the rising vapor to spin, creating a vortex. The Weather Connection A tornado forms when cool, dry air meets hot, humid air. The hot air rises quickly and creates strong winds. These winds spin and create a vortex that becomes tightly wound like a funnel. The vortex becomes a tornado when it touches the ground. Note: This exhibit uses a cool mist humidifier and fan and shows the direction of rotation for a THREE FOOT TALL tornado in the southern hemisphere. A real crowd pleaser!
