The Arctic wolf is least concern, but it does face threats. In 1997, there was a decline in the Arctic wolf population and its prey, muskoxen (Ovibos moschatus), and Arctic hares (Lepus arcticus). This was due to unfavourable weather conditions during the summers for four years.
"The Arctic air coming through Jan. 15th can be the coldest of the winter so far," Anderson said. "This batch of Arctic air will have a vast zone for fresh snow cover to work with and a direct ...
Japanese macaques can survive in cold temperatures of below −15°C (5°F), and are among very few primates that can do so. Chionophiles are any organisms ( animals , plants , fungi , etc.) that can thrive in cold winter conditions (the word is derived from the Greek word chion meaning " snow ", and -phile meaning "lover").
That means arctic air is blasting over the US, while pressure changes and the motion of the polar vortex whip up high winds and create a perfect recipe for wintry weather. Cold subsides when the ...
The original cold weather clothing was made of furs. The fibers of the fur trapped insulating air, lanolin on the fur repelled water. Knitted wool is an effective insulator when dry, but ineffective when wet. Goose down is the lightest insulator, and still used today. Its quality, called loft is a measure of its low density. It is ineffective ...
Driven by the jet stream, part of the polar vortex — a large area of cold air that spins over the North Pole in the winter — will drop about 3,000 miles south into the U.S., delivering the ...
The dry cold environment is the easiest of the four cold weather categories to survive in because of low humidity and the ground remains frozen. As a result, people and equipment are not subject to the effects of the thawing and freezing cycle, and precipitation is generally in the form of dry snow.
Roughly 50 million Americans are under a winter weather warning, advisory or watch on Friday as a major winter storm is forecast to bring hazardous snow and ice affecting large parts of the ...
