What’s a Heat Dome—And Why Is It So Dangerous? | #AskaMet?

A heat dome is like a giant blanket that traps hot air and won’t let it go.

Imagine you’re playing outside on a really hot day, and then someone puts a big, thick blanket over your head, you can't sweat, you can’t run, and the heat just keeps getting worse. That's what a heat dome does to a whole area. It’s like the sky is holding in all the heat from the sun.

A heat dome forms when strong winds push hot air up high in the atmosphere, and then they stop moving. This creates a sort of "lid" over the land, like the top of a jar, that keeps the hot air inside and stops cooler air from coming in. The heat just stays there, getting stronger every day.

When you're stuck under a heat dome, it's not just hot, it’s super hot, and it doesn’t let go. Your body can't cool down like it normally would, which makes it hard to breathe, think clearly, or even stay awake. It's like being in a sauna that won't turn off.

That’s why people get sick, tired, or even pass out, the heat dome is just too much!
