What are frontal passages?

Frontal passages are when weather changes happen because two different kinds of air meet and move past each other.

Imagine you're playing with your friend in a park. You both bring different snacks, one brings cookies, the other brings candy. When you sit down together, the cookies and candy mix, and soon everyone is sharing and tasting both. That mixing is like what happens during a frontal passage.

When warm air meets cold air in the sky, they don't just stay apart, they move past each other, kind of like you and your friend swapping snacks. This moving causes changes in the weather: clouds can form, rain might fall, or the wind might pick up.

If it's a cold front passage, it’s like your friend suddenly brings ice cream, things get cooler and maybe even rainy. If it's a warm front passage, it's more like you bring hot chocolate, everything feels milder and cozier.

So next time the weather changes, remember: it might just be two kinds of air having a little swap party in the sky!
