ENVIRONMENTAL SCIENCE: "WILD WEATHER: COLD!"

Here is the Donal McIntyre video on cold weather.   Note the information on polar winds moving to the south from the Arctic 'desert', the limits on human exposure to cold, what causes frostbite and the powerful winds at Mt. Washington.   Notice the concept of 'wind chill'.   Be aware that you are responsible to learn how to calculate wind chill factor as part of the "The Weather: Cold" handout.
