Learn English – the difference between fog, mist and haze

So, as the question says by itself: what's the context when I should use the word mist and the right context for fog? And haze?

The three have similar properties but have different size scales.

Haze is large scale like smog that you can see over long distances like obscuring a skyline or the horizon. I associate it with warmer dryer weather. It is very vague.

Fog is scientifically a low lying cloud, but when you're inside it, things are just not as bright and you can't see as far depending on how thick it is, and things feel a little cool and humid at the same time. There's very little differentiation inside, it's just heterogeneously a little less bright, and you can't see as far and it looks whiter in the distance, but there are no noticeable cloudy areas. Outside of it like from a mountain top you really do see that it is a cloud.

Mist is to me a kind of rain, or barely rain at all just a noticeable wetness in the air that an umbrella just really doesn't do anything to stop. You don't really see it falling but standing out in it, you eventually get wet.

Also, since language isn't logically consistent, a 'mister' outputs mist which looks like a small scale fog, a fog machine outputs very small scale fog that is hardly at all wet.

Hazy, foggy, and misty tend to follow all these but not always perfectly and usage would be modified as needed by idioms.
