Frontolysis

Frontolysis is a big word that means the breaking apart of a boundary between two different air masses. Imagine you are playing with two different types of play-doh, one is blue and the other is red. You mash them together to create a boundary, or a line where the two colors meet.

Now imagine you take your finger and you start to mix and push the play-doh together at the boundary. As you do this, the line between the blue and red play-doh starts to disappear as the two colors mix together. This is kind of like what happens in frontolysis, where two different air masses mix together and the boundary between them disappears.

So why does this happen? Well, usually it's because one of the air masses is weaker than the other. It's like having a strong football player on one team and a weak player on the other team. The strong player can push through the weak player, and pretty soon the weak player will be out of the way and the strong player can keep moving forward. It's kind of like that with air masses - a strong air mass can push through a weaker one and mix them together, causing frontolysis.

So that's what frontolysis is - the breaking apart of a boundary between two different air masses when one is stronger than the other and they mix together.
