Arctic Winds & Sea Ice

Danger ahead?
University of Toronto, March 20, 2018.

"A major shift in western Arctic wind patterns occurred throughout the winter of 2017 and the resulting changes in sea ice movement are possible indicators of a changing climate."

"Usually, the western Arctic has relatively stable weather during the winter; it is home to a quasi-stationary region of high pressure known as the Beaufort High, which promotes "anti-cyclonic" winds that travel in a clockwise direction and move sea ice along with it."

"Last year, we looked at the buoy tracks in the western Arctic and saw that the sea ice was moving in a counter-clockwise pattern instead and wondered why," Moore says. "We discovered that storms were moving in an unexpected direction from the Barents Sea along the Siberian coast and into the western Arctic, bringing with them low-pressures that caused the collapse of the Beaufort High."

"Generally, the Beaufort High drives sea ice motion throughout the Arctic as well as impacting ocean circulation over the North Atlantic Ocean. Any shift in movement patterns has the potential to affect the climate in these regions, as well as the Arctic ecosystem that depends on predictable areas of open water and ice."

"...the low-pressure systems were able to make inroads into the western Arctic because of an unusually warm fall in 2016 resulting in thinner and less extensive sea ice."

"If this becomes part of the normal pattern - even if it happens every few years - it will mean that the climate is changing."
