Regardless of the time of day (i.e. Earth's rotation on its axis), the North Pole will be dark, and the South Pole will be illuminated; see also arctic winter. Figure 3 shows the angle of sunlight striking Earth in the Northern and Southern Hemispheres when Earth's northern axis is tilted away from the Sun, when it is winter in the north and ...
At local noon the winter Sun culminates at −3.44°, and the summer Sun at 43.44°. Said another way, during the winter the Sun does not rise above the horizon, it is the polar night. There will be still a strong twilight though. At local midnight the summer Sun culminates at 3.44°. Said another way, it does not set; it is the polar day.
The effect of axial tilt is observable as the change in day length and the altitude of the Sun at solar noon (the Sun's culmination) during the year. The low angle of the Sun during the winter months means that incoming rays of solar radiation are spread over a larger area of the Earth's surface, so the light received is more indirect and of ...
Dōngzhì or Tōji (Chinese and Japanese: 冬至; Korean: 동지(Dongji); Vietnamese: Đông chí; lit. winter's extreme) is the 22nd solar term, and marks the winter solstice. It begins when the Sun reaches the celestial longitude of 270° (around 23 December) and ends when the Sun reaches the longitude of 285° (around 5 January).
Astronomical winter always starts on the solstice, which falls between Dec. 20 and Dec. 22. These dates vary from year to year due to leap years and the elliptical shape of Earth's orbit around ...
