Will there be a real extreme day in China?

Mohe is called Arctic Village because it is located in the northernmost part of China, so it can't be confused with real polar regions.

However, due to the high latitude of Mohe, the length of day and night in winter and summer varies greatly.

In summer, due to the high latitude, the days in Mohe are particularly long. Although there is no extreme daytime phenomenon, the afterglow of sunset can greet dawn, which is called white night. This is a natural phenomenon very similar to the extreme day. The difference is that it is extremely daytime-the sun does not set all day, and it is white night-with a short sunset.

In winter, because of the high latitude, the night in Mohe is particularly long, but after all, the day is short, so it can't be said that there is extreme night. However, sometimes you can see the aurora phenomenon.

The place where extreme day and night can appear on the earth only occurs within the southern Arctic Circle, that is, the north-south cold zone. Mohe can only be regarded as a cold temperate zone. It is also separated from the polar regions by a wide sub-frigid zone.

Keep answering your questions. But I remind you that your supplement is already contradictory. Only 24 hours of daylight is called extreme daylight, and similarly, only 24 hours of darkness is called extreme night.

You once admitted that the longest day in Mohe also had a short night; When the night is the longest, there are also times when the day is short. How can this be called extreme day and night phenomenon? As for the name, I have already said that when the day is particularly long, the afterglow of the sunset meets the dawn, and the night is not too dark and turns white. There is a famous Russian book called White Night.

In addition, let me talk about Helsinki, which is located near 60 degrees north latitude, but not in the Arctic Circle. Under this premise, no matter how close to the Arctic Circle, there will be no extreme day and night because the quantitative change has not reached the qualitative change. The place where extreme day and night phenomena occur must be in the polar circle.

Moreover, there is no extreme day and night phenomenon in Helsinki with higher latitude, and it is even more impossible for Mohe to have extreme day phenomenon.
