Storm Secret #3
Tornado Cousins
A dust devil is kind of like a tornado, but they’re mostly harmless and do not come from thunderstorms.
Dust devils often form on hot, sunny days. The ground gets very hot and heats the air directly above it. This hot air begins to rise quickly in a spinning motion. It lifts dust and sand from the ground to look like a tiny dust tornado.
Hurricanes come in many sizes, but here are some of the most common you’ll see.
The total size of most is about 300 miles (480 kilometers) wide. That would cover Ireland from top to bottom!
The calm, clear center of a hurricane, called the eye, is often 20-40 miles (32-64 kilometers) across. That’s about the width of some of the islands in Hawaii!
