The winds combined with temperatures at minus 30 have resulted in extreme wind chill values of near minus 40.
========================================
Whats with this wind-chill factor. Wind -chill is meaured an a cod steel body so what relation is there between a cold stell body and the humane tissue?

The relation is that the weather person wants to impress the public with their erronous weathjer for cast.

Retired, you need to brush up on your spelling.

I agree – alot of people do not understand wind chill. If you do then please ignore my little diatribe… Wind chill does NOT affect your car other than it will cool down quicker. If its minus 10 with a windchill of minus 40 your car will still only cool down to minus 10. Thats it, thats all. It will get there sooner but it will not go lower than the ambient air temperature… I promise you :)

Retired 02: Wind chill simply indicates the time it could take for skin to freeze at given temperatures and given wind speed. So say at -20 you may not freeze any exposed skin for a long time but add to that a 30KpH wind and it may freeze in minutes.

Windchill is just the media’s way of making it sound like it’s going to be a lot colder then it really is. I for one wish they would stop it.

-20 and windy is all they need to say.

axman, if you have to work outside knowing the windchill is very handy. If your sitting in an office, the cab of a truck on in a piece of equipment it means nothing.

lmorge,I’m old and grumpy and my fingers are a bit stiff and spelling is not the top priority for me. Please bare with me. Love ye all.

Thank you, Dragonmaster!! I don’t understand how people can argue with scientific fact and ways of communicating the danger if wind chill via temperature? What the heck is wrong with you guys??

relax Nao – Dragon and his link are exactly right. I dont see anyone on here arguing… just some people do not understand what wind chill means. I am just stating what I said from people who figure that the windchill is THE temperature. Alot of people say “Ive got to plug the car in, its minus 20 with the windchill” when the temp is minus 5…

Who cares about windchill …. I think most people understand the difference in sitting outside at the end of January if the air temperature is -10 clear sky, mid day, no wind, sun beating down on your body …..

and the same air temperature of -10, but cloudy sky, no sun, and a 25k/h wind directly into your face …….

in the first instance, you likely think it is warmer than -10, and in the second instance, you likely think it is very much colder ..

It is a life experience …

BTW, if you are into calculating building heat losses in order to size heating equipment for the climate the building is located in, it is very important to take average wind velocities into consideration since the laminar flow of air at the building surface provides less insulation at higher wind velocities.

And yes, the air immediately adjacent to the surface does contribute to the insulation property of the separation between the heated and unheated spaces.

Horrid conditions driving through the Pine Pass this afternoon. Very fine snow, cool temperatures and lots of truck traffic made for whiteout conditions some of the time.

Keep it between the ditches folks!

Please bare with me.

You’re on your own there I’m afraid! :) Especially when it’s this cold outside.
