Cold air damming typically happens in the mid-latitudes as this region lies within the Westerlies, an area where frontal intrusions are common.When the Arctic oscillation is negative and pressures are higher over the poles, the flow is more meridional, blowing from the direction of the pole towards the equator, which brings cold air into the mid-latitudes.

It has been also found that Arctic wolves scavenge through garbage. This sort of food source will not always be found in the Arctic wolf's diet because of regional and seasonal availability. [23] Sometimes there is debate whether the muskox or the Arctic hare is the primary prey for the hare-wolf-muskox predator-prey system.
In arctic or mountainous areas, the primary function of extreme cold weather clothing is to trap air as an insulator to prevent heat loss from the wearer's body. Secondary and necessary is to conduct water vapor away from the body to keep the insulating layers dry. A shell keeps the wind from disturbing the still air in the insulating layers.
The first arctic outbreak of the season is allowing temperatures to plunge across the eastern half of the country, creating "dangerously cold" wind chills of 15-30 degrees below zero in the ...
Polar lows have been referred to by many other terms, such as polar mesoscale vortex, Arctic hurricane, Arctic low, and cold air depression. Today the term is usually reserved for the more vigorous systems that have near-surface winds of at least 17 m/s (38 mph).
The Cold Regions Research and Engineering Laboratory (CRREL) is a United States Army Corps of Engineers, Engineer Research and Development Center research facility headquartered in Hanover, New Hampshire, that provides scientific and engineering support to the U.S. government and its military with a core emphasis on cold environments. CRREL ...
Two wolf subspecies that live in the northern Rocky Mountains: Canis lupus irremotus (left) and Canis lupus occidentalis (right) The northern Rocky Mountain wolf preys primarily on the bison, elk, the Rocky Mountain mule deer, and the beaver, though it is an opportunistic animal and will prey upon other species if the chance arises. But, for ...
Thermographic image: a cold-blooded snake is shown eating a warm-blooded mouse. Warm-blooded is an informal term referring to animal species whose bodies maintain a temperature higher than that of their environment. In particular, homeothermic species (including birds and mammals) maintain a stable body temperature by regulating metabolic ...
