First,about the car sweating, I used to think they figured humidity and
evaporative cooling in wind chill, but it's not that sophisticated.
I've looked at many wind chill calculators but none that I found ever
factor air humidity or moisture content on the person.
I just found this definition of wind chill.
A wind chill temperature is a calculation of how cold it would have to
be to cause the same rate of heat loss from your skin if there were no
wind blowing. Same goes for cars instead of skin.
I would like to see a *real* wind chill calculator.
You a weatherman?
You can find a lot by googling "Joint Action Group for Temperature
Looks like they don't include humidity. Probably because at the low
temperatures where wind chill is important there's not much moisture
in the air. More important in the heat index.
The whole damn wind chill index is mostly for TV weathermen
to scare people.
I can see using it to warn people when it's dangerously cold, but
sometimes they overdo it.
Sometimes I'll glance at the TV when the weather is on and see -10
all over the map when it's +20 outside.
Most people know you get cold faster when the wind is blowing.
Same with cars. Most people know your car will stay warmer longer
in an unheated garage instead of out in the wind.
Even putting the backside to the wind helps.
Though wind chill formulas only apply to human skin, it's all heat
transfer and can be applied to most anything.
I saw they use 95% percentile lowest skin conductivity in figuring
So most people will conduct more heat to the skin surface and not
freeze so fast as wind chills might indicate.
So if you want a real wind chill calculator you have to know your skin
Do you want to do all that?
I think you got that backwards. With low humidity in the air the
evaporative cooling effect is much higher. It also is much higher when
there is more moisture on the person, or object.
More important in the heat index.
Do you live in a big congested city? I do.
You need a lot of torque to maneuver around those road clogging SUVs
so you can get the next red light first. Also, city drivers like to
drive fast to discourage rural drivers from visiting.
You don't need a lot of horsepower, but the two tend to go hand in hand.
I gather you are referring to the SCION, a brand of Toyota. The Scion
XD is highly maneuverable, quick and efficient. It sips fuel, the
heater works nicely at sub-zero temps and the air conditioner keeps me
cool at ninty-five.
I was driving around Bethlehem, Pa. and I wanted to take that big
bridge (the hill-to-hill bridge?) because it was a big bridge and I
had to go that way to get home, but because of maybe a 1-way street I
couldn't go straight to it, so I drove around for 5 minutes and
finally got to it and across it, and I was right back on the side I
started on. Apparently I had gone over the Lehigh River when I wasn't
