What is polar?

What Does polar Mean

Polar is an adjective that is used to name what is linked to the poles . The concept of pole , for its part, usually refers to the points where the axis of rotation of our planet intersects with the celestial or terrestrial sphere.

It is possible, from these definitions, to develop various notions related to the polar. The polar circle is the parallel that is at 66 ° 33 ′ 44 ″ of latitude: in the case of north latitude, it is called the Arctic Circle while, in the South latitude, it is called the Antarctic Polar Circle .
When, in a polar region, a light appears in the sky caused by the collision between the solar mass and the pole of the Earth's magnetosphere , a polar aurora is produced . You can distinguish between the northern lights (which occurs at the north pole) and the southern aurora (at the south pole).

The polar bear , on the other hand, is the colloquial name of Ursus maritimus , a carnivorous animal of the Ursidae family that has its habitat in polar regions.
A very warm fabric that is used to make clothes that protects the person from low temperatures and winter conditions is also known as fleece , and even these garments can be called by this term.
Polar climate: characteristics, flora and fauna
Also called a cold climate , the polar climate has the characteristic of having temperatures below 0 ° C almost throughout the year, as well as an absence of humidity in the air, a great intensity in its winds and little rainfall, a combination of conditions that it makes survival difficult for species like humans.
As its name implies, this climate exists especially at the poles, being more severe in Antarctica than at the North Pole, with much lower temperatures . Interestingly, on the highest peaks in the world, such as the mountains of Alaska or the mountain ranges of the Andes and the Himalayas, the climate is very similar to polar.
The polar climate belongs to a classification in which the cold continental climate (typical of the northwest and north of the European continent , central Siberia, Alaska and Canada) and the mountain climate (in the nearby mountainous regions) are also found. to Ecuador whose altitude exceeds 3500 meters above sea level or 1000 in cold regions).

In the interior plateau of Antarctica the temperature of the months of polar night and those of high sun varies a lot; the difference between the summer and winter of the South Pole station, for example, can exceed 30 ° C. With respect to its rainfall, it usually occurs in the form of snow and with a lot of wind, which makes its measurement difficult .
In the Antarctic peninsula, on the other hand, which is the portion of the continent that is further north, these thermal contrasts do not occur and the rains are less scarce thanks to the passage of the frontal systems. To the west the climate is maritime (with less violent temperatures and a higher percentage of humidity) and to the east the temperatures are usually lower and the ocean is covered with ice throughout the year.
The reason that the polar climate is colder than the others is that the sun's rays do not hit the poles as directly as they do on the rest of the planet. Some of the species of polar flora are lichens, bushes and mosses, while its fauna includes the arctic hare and fox and the aforementioned polar bear.
