Windchill is ********. By which I mean that it doesn't actually convey

If it is +1C and there is a 'windchill' of 5 degrees, there wont be a
frost, as if it were -4C. If you wear windproof clothing then it feels
exactly the same as +1C. Obviously, air movement and humidity do have
an effect on your perception of temperature, but then so do your own
movement (standing still vs walking/running/cycling), clothing, skin
moisture levels, etc. - how much colder it feels than dry still air is
entirely subjective.

Sorry, personal bete noire. I'll shut up now...

By the same token surface temperatures of Arctic ice in storms only
get that low because of being ice in the Arctic? I would have thought
that the wind effect did the chilling.

The fact that the temperature just a few feet lower down remains
within 2 degrees of 0 Centigrade despite frequent sustained drops to
-37 above?

Kind of reminds me how temperatures in the lower atmosphere don't
change much though powerful storms can gather vast quantities of water
and vaporise it.

My personal "black fire". No apologies tended.
