It is the artic circle. It is 66 degrees north of the equator!
That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).That varies a lot depending on the latitude, from 12 hour day throught Winter and Summer (at the equator), to the Sun being above the horizon all the time, i.e., 24-hour day (in summer, north of the northern polar circle or south of the southern polar circle), or all the time under the horizon, i.e. 0-hour day (in winter, north of the northern polar circle or south of the southern polar circle).
The Polar Satellite was the name for a NASA science spacecraft which was launched February 24, 1996, to observe the magnetosphere. Polar was in a 86 degree orbital inclination with an orbital period of roughly 17.5 hours. The Polar Mission Operations were terminated on April 28th, 2008. Any satellite with a 90 degree tilt is considered to have a "polar orbit", as it allows the satellite to view every latitude of the Earth including the north and south poles.
The su polar low lies along the polar jet stream :)
Saturn-with a polar flattening of 10.4%
Polar orbits pass over the north and south poles of the Earth.
The Arctic Circle
The parallel of latitude that circumscribes the polar tundra zone is the Arctic Circle in the northern hemisphere and the Antarctic Circle in the southern hemisphere. These circles mark the boundary where the tundra biome transitions into the polar ice caps.
Arctic Circle
It is the Arctic Circle and it is approximately 66 degrees north of the equator.
Very far south. It is cold and so then the latitude will probably be negative. If you thought it would be positive, you are crazy.
There are several other names for high latitude areas of the world. There is the Arctic/Antarctic, tundra/taiga, and several other things.
An Alpine Tundra has permafrost however, Alpine Tundra is found at the tops of tall mountains. Polar Tundra is found near the North and South Poles. The alpine tundra is found at any latitude. Polar tundra has snow covering its surface. The alpine tundra has grass covering its surface. The alpine tundra also has delicate plants that take 4-5 years to flower. One piece of trash could kill a flower that is decades old in just a few weeks.
Being a polar or high latitude climate, the tundra is noted for its low temperature. The tundra is basically summer-less, having no monthly temperature averaging above 10o C, and having at least nine months below freezing.
The word 'polar' defines the latitude. Should the latitude change it would no longer be polar.
Polar ice ! ;)
Tundra
The longest parallel of latitude is the one defined as 'zero degrees', known as the "Equator". All meridians of longitude have the same length ... 1/2 of the earth's polar circumference.
