What will happen in the Arctic during the winter solstice?

During the winter solstice, there will be an extreme night in the North Pole.

After the autumnal equinox, the polar night appeared near the North Pole, and then the polar night range near the North Pole became larger and larger. The winter solstice reaches its maximum and the boundary reaches the Arctic Circle. After the winter solstice, the polar night range near the North Pole gradually shrinks to zero at the vernal equinox.

Extreme night, also known as eternal night, is the phenomenon that the sun is below the horizon in a day in the polar regions of the earth, that is, the night lasts for 24 hours. Both the North Pole and the South Pole can be divided into extreme days and nights. In a year, it is extremely bright for six months in a row, and it is extremely night for six months. During the polar night of a stellar month (about 27.3 days), you can see the moon for half a month, but you can't see the other half.
