You see that the person doing the recording is basically standing on a big fuckoff wall, right? The two sides are simply isolated by said big fuckoff wall and stuff like fog can’t spread over to the other side. mountains also alter winds and cause clouds to get stuck so you can have rainfall on one side and sunny weather on the other.

As air rises, it cools, which means its capacity to hold water vapor decreases. So as wind blows over a mountain range, a lot of the water can be squeezed out, forming clouds or even falling as rain. Then the wind goes down the other side, becoming warmer and dryer. So the land downwind is in the “rainshadow” of the mountain range.

As air pushes into the side of a mountain range it is forced upwards due to the barrier, as the air rises it cools, cold air can’t hold as much moisture as warm air so the moisture condenses out of the air and rains heavily leaving cold dry air passing over the mountains which won’t rain anymore until it picks up more moisture. If the wind constantly blows in one direction it will be dry on one side and wet on the other. https://youtu.be/8Lcvwx63Xg0
