"It’s been a major breakdown,’’ said Jennifer Francis, a climate scientist at the Woodwell Climate Research Center on Cape Cod. This week’s weather is part of a pattern stretching back to January. Meteorologists say particular polar vortex breakdown has been one of the biggest, nastiest and longest-lasting ones they've seen - something that has been tracked since at least the 1950's. It’s been happening more often, and scientists are still not completely sure why, but they suggest it's a mix of natural random weather and human-caused climate change. But occasionally something slams against the top, sending the cold air escaping from its Arctic home and heading south. That's the polar vortex, which spins like a whirling top at the top of the planet. The record subzero temperatures impacting warmer places has been blamed on the polar vortex, a weather pattern that usually keeps to the Arctic, but is increasingly visiting lower latitudes.Īround the North Pole, winter’s ultra-cold air is usually kept bottled up 15 to 30 miles high. ![]() month, and year of interest for either snowfall or snow depth data.
