Visualization of the ice and snow covering Earth's northern and southern polar regions Northern Hemisphere permafrost (permanently frozen ground) in purple. The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.
The reasons are the two cold currents: California Current at Northeast and Humboldt Current along the equatorial line. The Hawaiian Islands (in white) have higher temperatures than the equatorial line near the coast of South America because cold waters from upwelling along the California coast are farther away than the thermal equator, and ...
Ice cap climate is the world's coldest climate, and includes the coldest places on Earth. With an average temperature of −55.2 °C (−67.4 °F), Vostok, Antarctica is the coldest place in the world, and has also recorded the lowest temperature, −89.2 °C (−128.6 °F). [ 3 ]
Solar radiation has a lower intensity in polar regions because the angle at which it hits the earth is not as direct as at the equator. Another effect is that sunlight has to go through more atmosphere to reach the ground. [1] The polar climate regions are characterized by a lack of warm summers but with varying winters. Every month a polar ...
Both philosophers theorized the Earth divided into three types of climatic zones based on their distance from the equator. Like Parmeneides, thinking that the area near the equator was too hot for habitation, Aristotle dubbed the region around the equator (from 23.5° N to 23.5° S) the "Torrid Zone."
The coldest reliably measured temperature in Verkhoyansk was −67.8 °C (−90.0 °F) on February 5 and 7 of 1892. On February 6, 1933, a temperature of −67.7 °C (−89.9 °F) was recorded at Oymyakon's weather station. [5] At the time, this was the coldest reliably measured temperature for the Northern Hemisphere.
Aerial photograph of Vostok Station, the coldest directly observed location on Earth. The location of Vostok Station in Antarctica. The lowest natural temperature ever directly recorded at ground level on Earth is −89.2 °C (−128.6 °F; 184.0 K) at the then-Soviet Vostok Station in Antarctica on 21 July 1983 by ground measurements.
Landscape near Oymyakon in February 2013 The weather station. With an extreme subarctic climate (Köppen climate classification Dfd, Trewartha climate classification Ecle), Oymyakon is known as one of the places considered the Northern Pole of Cold, the other being the town of Verkhoyansk, located 629 km (391 mi
