polaarpäevadel

Polaarpäevadel, also known as the midnight sun, refers to the period of continuous daylight experienced in the polar regions during the summer months. This phenomenon occurs when the sun remains above the horizon for more than 24 hours. The exact duration of the polar day depends on the latitude. The closer one gets to the geographic poles, the longer the polar day lasts. At the Arctic Circle and Antarctic Circle, the polar day lasts for approximately 24 hours once a year, around the summer solstice. Further towards the poles, this period extends. At the North Pole and South Pole themselves, the sun can remain visible for about six months continuously.

The opposite of the polar day is the polar night, where darkness prevails for extended periods during the winter. These extreme variations in daylight have significant impacts on ecosystems, wildlife, and human life in the polar regions. Flora and fauna have adapted to these unique light cycles, with many animals exhibiting specific behaviors related to the presence or absence of sunlight, such as migration or hibernation. Human societies in these areas have also developed cultural practices and lifestyles that accommodate the prolonged daylight or darkness.
