Called a Sudden Stratospheric Warming (SSW), it occurs when the temperature of the stratosphere (30-50km above ground) over the South Pole rises by more than 25ᵒC.The Southern Hemisphere is characterised by a cold Antarctic continent surrounded by relatively warm seas.

NIWA staff plunge into Evans Bay for their mid-winter's swim on 20 June 2019. NIWA forecaster Ben Noll says in the Far North, the winter solstice has about 4 hours and 45 minutes less daylight than the summer solstice, but in Southland the difference is more than 7 hours.

Even after a discovery in 2006 showing 400 piping plovers wintering in the Bahamas, researchers likely only know where half the population spends much of its year, says Jeffery.

Recent analysis by NIWA has shown that about 800,000 New Zealanders are exposed to fine particles in the air that exceed World Health Organisation guidelines every winter, the majority of which is due to home heating emissions.

"As long as you dress warmly outside, you're not in danger." The series also documents the creative ways Yakutsk residents manage the cold, including building their houses on stilts so the central heating doesn't melt the permafrost—in Russia, Yakutsk is known as "the city on legs"—and placing all sewage, water, and utility lines above ground to keep them from freezing.

“You don’t have as much power when you want to discharge,” says Stefanopoulou, “The situation is even more limited when you want to charge.” Modern cars are designed to take that into account, with battery thermal management systems that warm or cool a battery.

“High school students can now do things that the best researchers in the world could not have done a few years ago,” says Andrew Ng, an AI researcher and entrepreneur who has led big projects at Google and China’s Baidu.The A.I. IssueClive ThompsonHow to Teach Artificial Intelligence Some Common SenseJessi HempelFei-Fei Li's Quest to Make AI Better for HumanityShaun RavivThe Genius Neuroscientist Who Might Hold the Key to True AIPeople like Ng have big hopes for the amateur AI explosion: They want it to spread the technology’s potential far from Silicon Valley, physically and culturally, to see what happens when tech outsiders “train” neural networks according to their own priorities and ways of seeing the world.

During years with low seasonal sea ice concentrations (when there’s more heat loss from more exposed open water), the north-south differences in atmospheric temperatures across the Barents Sea are reduced.

A NASA satellite image shows where the ice has pulled away from Greenland's north coast, a phenomenon that's never been recorded before.

Dr Mullan defined a winter’s day as one in which the daily average temperature was less than a selected threshold and then compared the number of days this occurred for two 30-year periods, the first from 1909 to 1938 and the second from 1987 to 2016.
