How are thunderstorms formed? | Weather Wise?

Thunderstorms are big, noisy storms that happen when hot air and cold air have a little fight in the sky.

Imagine you're playing with your friend in the park. You both want to swing on the same swing, one of you pushes up, and the other pushes down. That's like what happens with hot and cold air.

On a sunny day, the ground gets really warm, especially near lakes or ponds, where water helps keep things cool nearby. This makes the air right above it warm too. Warm air is lighter than cold air, so it wants to go up, like when you let go of a balloon and it floats into the sky.

As the hot air rises, it carries water vapor with it. When this warm, wet air meets cooler air high in the sky, it cools down and turns back into tiny droplets or ice crystals, just like when you take a cold drink out of the fridge on a hot day, and little drops form on the outside.

These droplets and ice crystals bump into each other, creating lightning and thunder, and that’s how a thunderstorm happens!
