ELI5: Explain Like I'm 5

Potential temperature

Okay kiddo, so you know that when things get hotter, they rise up, right? Like when you blow up a balloon and let it go, it flies up because the air inside gets hot and rises.

That’s kinda like what happens in the air around us too. When the sun heats up the ground, the air near the ground gets warmer and rises up. But as it rises, it cools down because it’s moving away from the heat source (the ground).

Now, scientists have a way of measuring the temperature of the air at different heights. They call it potential temperature. It’s like a special temperature that tells you how hot or cold the air would be if you lifted it up or down to a certain height.

And why is this important, you might ask? Well, because it helps scientists understand how air masses move around and mix with each other. They can use it to predict weather patterns and air pollution, and even study the climate!
