Hoskins effect

The Hoskins effect is a big word that helps explain how air moves around when it is flowing over or around something. Imagine you are blowing air onto a big ball - the air moves around the ball and creates different types of movements.

Now, the Hoskins effect happens when air flows around a mountain. The mountain makes the air move in a certain way - kind of like if you put your hand in front of a fan and the air changes direction. The air gets forced up and over the mountain and as it does that, it gets colder and wetter because it meets clouds. The opposite happens on the other side of the mountain, where the air goes down and becomes warmer and drier.

So, the Hoskins effect helps to explain why things like mountains can create totally different weather patterns on either side. It's like magic!
