Climatic characteristics of the Arctic region

In addition to the well-known cold and desolation, compared with the Antarctic, a major feature of the Arctic is that most areas are covered by the ocean, or by salty sea ice instead of fresh water ice. Especially in the area above 82 degrees north latitude, the sea ice is continuous and does not melt all the year round, which leads to two tourism-related results: all kinds of animals and plants, including polar bears at the top of the food chain, can't survive, and commercial cruise ships are basically not the destination of arctic blue because of the hard ice-except visiting the geographical North Pole.

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.
