The consequences of the unusual extreme weather in the Arctic continue with strange flashes of lightning hundreds of miles from the pole.
The National Weather Service in Fairbanks, Alaska, recorded a number of lightning flashes about 482 km from the North Pole, on Saturday, August 10.National Geographic reports put the number at 48, making the disturbances more extreme than other similar events.The national weather service, in a tweet on Twitter, published by climate scientist Bryan Breitner, revealed that the strange event in the north is unlike any lightning strikes present in modern memory.
Lightning is usually the result of two different fronts: one less warm and humid, the other cool and dry higher.Although the confluence of these two conditions in the atmosphere may be typical elsewhere around the world, the phenomenon in the Arctic - known as cold temperatures - means that Earth's temperature is moist enough to stimulate lightning.
According to a report by National Geographic, unusually divergent fronts can be fueled by the rapid melting of sea ice in the Arctic Sea.It is a year of exceptional warmth and sea ice receding throughout the Arctic, said Rick Thoman, Alaska climate specialist at the International Arctic Research Center. Without this ice, the waters of the Arctic Sea continue to be heated by the sun, forming warmer waters and subsequent fronts.
