Meteorologists stunned by the rare Arctic Lightening storms in Alaska

Meteorologists were stunned this week when three successive thunderstorms swept across the icy Arctic from Siberia to the north of Alaska, unleashing lightning bolts in an unusual phenomenon that scientists say will become less rare with global warming.

“Forecasters hadn’t seen anything like that before,” said Ed Plumb, a National Weather Service meteorologist in Fairbanks, speaking about the storms that started on Saturday.

Typically, the air over the Arctic Ocean, especially when the water is covered with ice, lacks the convective heat needed to generate lightning storms.

But as climate change warms the Arctic faster than the rest of the world, that's changing, scientists say.
