A detailed analysis of polar vortex collapse mechanisms and how they relate to occasional North American cold outbreaks. Based on recent meteorological studies and stratospheric data, the video ...

In the remote, icy expanse of the Arctic, the survival of a species begins with a remarkable act of resilience and devotion. The journey of a polar bear mother, from conception to raising cubs in ...

Polar bear cubs are typically born between November and January, deep within the safety of a snow den. The mother remains in the den without eating or drinking, wholly devoted to nursing and ...

WHAT ARE THE ARCTIC OSCILLATION, NORTH AMERICAN OSCILLATION AND MADDEN-JULIAN OSCILLATION? Precipitation patterns can also greatly affect temperatures, which are expected to be on the toasty side for ...

Often the polar vortex flows in a tight coil around the North Pole, containing the Arctic air, but Cohen’s study, and other research, suggest a trend to more frequent stretched polar vortexes ...

The Arctic Oscillation has been in a positive mode for most of the northern spring and early summer. This reflects the polar jet stream being displaced farther north than usual, helping midlatitude ...

Life in the Arctic is harsh and unforgiving, but the polar bear has perfected survival in one of the most extreme environments on Earth. As the largest land predator, the male polar bear can grow ...

Now, a new study suggests that these cold extremes are due to an increasingly common pattern in the polar vortex, the zone of low pressure that usually circulates over the Arctic.
