any hoar frost in Surrey valleys this morning ?
 

Thanks for the advice Phil. Freezing fog and -6c at 7:30am but worth the
trip, fog cleared rapidly around 8:30. A few pics uploaded here :.

Actually, I was surprised how iced up the car was this morning. I would
give it a go tomorrow Terry - think there may be a bit more hoar frost.
Min -4.3c at Merrow.
Frost still on the ground in shade (11Z)

Beautiful photos - looks like the new camera knows a thing or two ;-)

Lovely photos. Definately worth getting up for. I cycled down from the New
Inn at Send to the town centre a couple of weeks ago and it looked like
Summer! Send Church always looks great in the scenery.
-6c also here, not quite beating the -6.2 on Dec 20th.

It's usually chilliest just at dawn, or just after is it not?

No. It's between 4-5am.

Sorry, this just isn't true. It is coldest soon after sunrise
and I have 24 year's thermograph traces to prove it. There is no
reason why the temperature should rise before sunrise in the absence
of any change of wind or cloud.

Of course there is - the central heaing comes on at 7 am!

Ford Transits don't have central heating, fool.

Bzzt wrong. Som Ford Transits have central heating.

Yebbut that doesn't take into account windchill.

I've spent years being at work at that time.

Windchill is ********. By which I mean that it doesn't actually convey
any useful information;
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...

Wind chill.

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.

That's nowt to do with wind chill, or indeed the wind. The temperature is
that of the air. Air at a certain temperature can't cool below that
temperature - simple thermodynamics. The wind can make the cooling effect if
present work faster, but it won't change the equilibrium temperature.

Insulation.

"Wind chill" refers to the cooling of warm bodies, ie people - stick
somebody in still air at 0 deg C and they'll require X amount of energy to
keep warm. Make the air moving and they'll require more, ie they'll require
Y amount of energy. If the air is still, they'd expend Y amount of energy at
several degrees below - the wind chill is the difference between the actual
air temperature and that lower temperature.
