The Arctic circle is the outermost parallel circle counted from the North
Pole where during the summer solstice the sun doesn't go under the horizon during any hour
of the day or night. This phenomen is called the midnight sun, polarday or polar- summer.
The Arctic circle is also the outermost parallel circle counted from the North Pole where
we can't see the sun rise over the horizon in the winter solstice. This phenomen is called
polarnight, darkness at noon or midwinter darkness.
It's the earth axis inclination to its course around the sun which causes the seasons,
midnight sun and the midvinterdarkness. It's also the same inclination that definies where
the Arctic circle goes.
The gravitation of the planets in the solar system changes the orbit of the earth so that
the inclination is reduced. This is the reason for the Arctic circle movement to the north
with a speed of 14,5 m/year. |

This movement is a part of a long periodic movement in which the Arctic
circle's latitude varies with a few degrees during a laptime of about 40 000 years.
The longperiodic movement of the Arctic circle covers a wide area. In Torne valley,
between a line in the south of Haparanda and a line quite north of Pajala.
Today halfway on the movement to the northern turning point, the Arctic circle is in
Juoksengi and will stay within the village for about the next 300 years and that´s Ok ! |
