Weather Wisdom: 6th graders from Avoca Central School

Weather Wisdom

The sixth grade class from Avoca Central School was featured in this week’s Weather Wisdom. Hayden asked, “How do tornadoes form?”

Ingredients for a tornado include moisture, change in temperatures, unstable atmosphere, lift, and wind shear.

When cold dry air mixes with warm humid air, this creates a lift in the atmosphere. Winds then come into play, something meteorologists refer to as wind shear- winds rotating and increasing speed with height. This can create a spinning horizontal column of air. A downdraft from a thunderstorm will cool that column of air down to the ground producing the tornado.
