VIDEO – A depression affecting the North Atlantic generates temperatures between 0 and 2 ° C in the region, much higher than those normally found at that time. In other parts of the world also, the illustrations of an exceptional winter climate-continue.
A summer time months December. It’s a bit the feeling that we had, in France and elsewhere in recent weeks, but that’s the reality of the current situation in the North Pole. Wednesday, mercury is achieved between 0 and 2 ° C, above the level of 20 degrees to the normal season. Usually the temperature approaches freezing point only during the summer.
This temperature increase is due to a “powerful and violent” depression that affects the North Atlantic under Canadian weather services . After knowing in eastern Canada a Christmas unusually warm (15.9 ° C on December 24 in Montreal often close to averages of -10 ° C usually), this depression has won the North Atlantic Ocean. She is currently centered on Iceland, making it drop the pressure of the air at 928 hectopascals and resulting winds 140 km / h and waves of 15 meters high.

“This is an extremely powerful and extremely violent depression, so it’s not surprising that temperatures are pushed so hot and north winds affecting England, “where the army was mobilized against weather, told AFP Natalie Hasell, meteorologist at the Canadian Ministry of the Environment. “This deep depression advancing warm air to the North Pole, where temperatures are at least greater than 20 degrees C compared to the normal” lying “around the freezing point 0, 1 and 2 degrees “added the specialist in extreme weather events.
US scientists from the North Pole Environmental Observatory (NPEO) found that the mercury had climbed sharply the past two days, from -37 ° C Monday -8 ° C Wednesday on a tag in the Arctic located about 300 km from the North Pole.
Too early to link this phenomenon to climate change
The Arctic is the region most affected by global warming globe, now with higher temperatures of three degrees minimum compared to pre-industrial times, according to international institutes. The snowfalls are more frequent there, strongest winds and the sea ice is in constant decline for over 30 years.
It would be too early to link the mild temperatures observed at the end 2015 at the North Pole global warming, warned Natalie Hasell, noting that meteorologists are not based their conclusions on a “one anomaly “. Especially since the Canadian National Meteorology has no records of temperatures on the roof of the Earth. However, “it’s really weird to have temperatures around 0 in late December at the North Pole,” noted the expert. Natalie Hasell emphasizes that depression, with warmer temperatures would move in the coming days to Siberia in northern Russia.
The El Niño phenomenon in question
Capital of Inuit territory of Nunavut, northeast of Canada under the Arctic Circle, Iqaluit recorded at Christmas temperatures of -4.6 ° C and -4.9 ° C, -21 ° C against average, never seen again. Baffin Island, on which is Iqaluit, even experienced rains in December, said David Phillips, meteorologist at the Canadian Ministry of the Environment. “This is probably El Niño who ventures to North,” he told AFP. This climatic phenomenon that occurs every four to seven years on average and has already made about him this year. Caused by a change in direction of the trade winds over the equatorial Pacific Ocean, El Niño episode in 2015 knows probably the most powerful in the last 100 years. Coupled with global warming, it generated extreme weather events such as floods, tornadoes, heat waves.
These non-standard temperatures at the North Pole echo many events of an exceptional winter climate of the plan. Particularly soft in Europe, it already generates a disturbance of vegetation, while there are flowering trees as bright spring. At the same time, the city of Istanbul faces on Wednesday in disturbances in its transportation due to heavy snowfall. Turkish Airlines has canceled 265 flights departing and arriving at Ataturk Airport and 37 others who were to take off or land at Sabiha Goksen. The airline company Pegasus costs low has in turn canceled 34 flights.
If the arrival of a white winter coat is a frequent occurrence in Turkey, the amount of snowfall is her unusual . The Istanbul Municipality announced Wednesday it had mobilized 1,000 vehicles and machines to keep the roads open, while praying the population to limit its movements. Further snowfalls are expected on Thursday. A similar phenomenon had occurred in February.
