A heat dome is like a giant blanket that traps hot air over a place, and it’s making the US really, really hot right now.
Imagine you're wearing a thick winter coat on a sunny day. The sun shines through your coat, warming you up from the inside. That's kind of what happens with a heat dome. It acts like a lid on top of the air, keeping all that heat from escaping, so it just gets hotter and hotter below.
How the Heat Dome Works
The sun is shining down on the ground, heating it up. The hot ground warms the air above it. But when the air starts to move, like a big fan, it brings in more warm air and stops the cool air from coming in, trapping all that heat.
It's like being inside a greenhouse with no windows: the sun comes in, but the heat stays inside.
Why It Feels So Hot
When the heat dome is strong, it’s not just hot outside, it feels like you’re standing next to a giant oven. The air doesn’t move much, so your body can't cool down easily. That's why people feel dizzy or tired during a heatwave.
It’s like being stuck in a really warm room with no way out, and the sun is making it even warmer! A heat dome is like a giant blanket that traps hot air over a place, and it’s making the US really, really hot right now.
