What’s Behind This Endless Winter? Scientists Point to Melting Arctic Sea Ice – Global News
Article Synopsis – Scientists believe the exceptionally long winter this year is due to a weakened jet stream, which normally holds back icy Arctic air. “The jet stream is powered by the temperature difference between the Arctic and mid-latitudes. The warming Arctic weakens the jet stream”. According to climatologist Jennifer Francis, “When the jet weakens, it tends to take these bigger north and south swings. When it takes one of these big southern swings, it allows all that Arctic cold air to plunge much farther south than it normally would and it tends to stick around there longer”.
