Looking from within, it's difficult to tell, but would you say that the rest of the world glances at Britain and thinks, "There's a bunch of folk preoccupied with the weather."? It's a stereotype that's hard to shake off... unlike the raindrops, snowflakes and hailstones.
(And, yes, at the moment, the rest of the world probably also thinks several other things about Britain. Some things more uncertain and foggier than others, and with little chance of a ray of sunshine any time soon).
Our fascination with the weather comes from, I guess, being a small island located off the coast of a large continent. Whatever meteorology happens by, the only constant is that it will be changing frequently. Hence our need to discuss it at the drop of an oilskin hat.
Now imagine an even smaller island, located off the coast of said small island and ramp up the speed of change. Not to mention the speed of the meteorology!
That's where we are now... equinoctial gales and unsettled weather. After such a glorious Summer, it comes as something of a shock when the sky returns to default settings (though less annoying than when your Sky does a factory reset and loses all your recordings. I'm guessing here, as I'm too tight to pay for all that malarkey).
It's a time of many rainbows... single arcs, double arcs, arc fragments, diffuse arcs... plenty of arc-itecture, really. Although maybe we have the same amount as everyone else, just we also have the big skies which allows us to see them?
But, as I alluded to earlier, these features are ephemeral, as is the weather which produces them. It's never too long before something else rattles through.
Perhaps those weren't good examples, there's patently nine hours between the last two photos, which were taken from the same spot.
