Antarctic Polar Vortex Is Now Spinning in the Wrong Direction and Could Impact Global Weather
The Antarctic Circumpolar Current (ACC) is a large ocean current—or polar vortex—that flows clockwise around the continent of Antarctica, with wind speeds of around 155 miles per hour. But due the impacts of climate change, the vortex has been gradually growing faster and faster over the past several years. The most recent change to the trajectory of the vortex occurred on March 4, when it started spinning backwards.
