Climatic characteristics of the Arctic region
The Arctic in winter has two characteristics: aurora and polar night. Aurora can be seen above 60 degrees north latitude, especially in Iceland, Norway, Alaska and northern Canada. Extreme night refers to a day when there is no sun all day. With the increase of latitude around the Arctic Circle from winter to sun, the extreme night becomes longer.
In summer, there will be extreme sunlight around the Arctic summer solstice-the sun does not set all day, but increases with the increase of latitude, which can last for more than two months near 80 degrees north latitude. Although the temperature in the Arctic is much higher in summer than in winter, it is still very cold-especially when the wind is strong, the weather changes quickly, so keep warm at all times.
