One thing about this weather report app that irritates me every day that I take notice is Visibility.
So we can see 24 kilometres, but only if we’re looking into the sky, at clouds. Or if you yourself are in space.
If you stand at sealevel, looking out over the sea, the horizon is about 4.8 kilometres away, and this is for a man of average height which is 5’ 10” or 1.75 metres.
If you look inland and you’re not standing on a mountain, it’d be a lot less, what with the lumps and bumps of most of the Earth.
