Got him re-elected no? Must work on some level?

Never stoop that low and immitate that dork. 🙂

In other words, since non-skin areas aren't affected
by wind chill exposure (i.e., they won't freeze to
death), wind chill effects calculated using areas
other than human skin aren't of any useful application,
weather wise.

It'll make the difference between whether your car will or won't start
after a couple of hours in -30. Two hours with no wind, most modern
cars will start no trouble. Two hours in a howling wind - you may be in
trouble.

Well, you then disagree with the stated observation
that wind chill can chill only to ambient air temp
and no more. Beyond reaching that temp, time is
not a factor.

If the wind can't get in to physically affect
the warmed air from layering it also can't
cool that air more quickly. Gore tex is a
pretty effective wind barrier.

Practical experience: Goretex helps a lot, but if there's a wind you
will be colder than without the wind, I don't care what you're wearing.

Speculation mode on why that's so: There will be a temperature gradient
from your skin through the various layers of insulation. The goretex is
part of that system, and the wind is going to keep it at the ambient
outside temperature, whereas without a wind it will heat up some. So
the wind will cause heat to dump out of the system more quickly.

There's something to that, but it all depends
on the layering and activity (meaning the types
of layers and thickness/insulating properties
of those layers.)

OTOH, there's are physical/psychological factors
to wind aside from actual heat erosion. I think this
is likely more of a factor than the wind chill itself
if the layering is such that wind chill is largely
negated.

Best President since Kennedy. Sure glad that he has a few old farts upset
as it means he is on the right track.

You're right Doug. Because if I got invited to dinner by that
crowd...it would be cool until I showed up. Then it would be "Guess
Who's Coming To Dinner"! LOL!

Let's correct that. You mean the best _king_
since George III.

George III and George W have a lot in common
regarding their vision of government in America:
More power concentrated in the hands of a few and
less power in the hands of the governed. They also
share a common love of diplomacy by military force.

Oh yeah, also both spoiled rich brats raised on
silver spoons...

My apologies. I'll have my crow medium-well thank you. For a
minute there Tony thought you were one of these southern weenies like
Phil, etc.....speaking out of school. (hey Phil, no offense)

Actually sounds like Phil kicked butt doing a 14 mile trail run in
20's f with 15-20mph winds last Sunday. To me runs longer than an
hour in the cold are much harder.

It wasn't that bad. I think the trees blocked the wind quite a bit. Just my
hands and my butt were cold. This Sunday I've got a 19-miler scheduled.
There is supposed to be an ice storm coming to north Georgia tomorrow, but
it should be in the upper 30s F by Sunday's run. I think I'm going to get
some of these hand warmers (http://tinyurl.com/56vfw), since even 2 pairs
of mitts don't keep my hands warm enough. Other than that, when I'm running
in these temps I'm quite comfortable, especially when I remind myself what
you, Lance, David, Doug, Dot, and Donovan, have to endure in order to keep
training.

Didn't say that anywhere - I was trying to point out that cooling rates
apply for people and things. Two hours in -30C with no wind, the engine
won't cool to ambient. Eight hours with no wind, that engine will probably
be as cold as it's going to get. If it's windy, it's going to get to
ambient (or as we say, dead cold) faster. If I'm somewhere without access
to electricity for my car's block heater and it's really cold, I'll go out
and start it every 2 or 3 hours. If I leave it all day, it may well not
start.

Did I mention that it can be really cold where I live? Modern cars with
fuel injection are pretty good in the cold - they'll start down to -20C or
so no problem. Once you get to -30C or worse it gets ugly for machinery.
