In midsummer, as the sun reaches its maximum elevation of about 23.5 degrees, high temperatures at the South Pole in January average at −25.9 °C (−15 °F). As the six-month "day" wears on and the sun gets lower, temperatures drop as well: they reach −55 °C (−67 °F) around sunset (late March) and sunrise (late September).
Global surface temperature (GST) is the average temperature of Earth's surface. More precisely, it is the weighted average of the temperatures over the ocean and land. The former is also called sea surface temperature and the latter is called surface air temperature. Temperature data comes mainly from weather stations and satellites.
The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.7″ S and the Antarctic Circle at 66°33′50.3″ S, covers 25.99% of Earth's surface. The South Frigid Zone, from the Antarctic Circle at 66°33′50.3″ S and the South Pole at 90° S, covers 4.12% of Earth's surface. Earth's climatic zones
The South Pole is the other point where Earth's axis of rotation intersects its surface, in Antarctica. Earth rotates once in about 24 hours with respect to the Sun, but once every 23 hours, 56 minutes and 4 seconds with respect to other distant stars . Earth's rotation is slowing slightly with time; thus, a day was shorter in the past.
At the South Pole, considered the coldest point on Earth, temperatures are rising fast. Temperature data shows that the desolate region has warmed at three times the global warming rate over the ...
At the South Pole, the highest temperature ever recorded was −12.3 °C (9.9 °F) on 25 December 2011. [16] Along the Antarctic Peninsula, temperatures as high as 18.3 °C (64.9 °F) have been recorded, [clarification needed] though the summer temperature is below 0 °C (32 °F) most of the time. Severe low temperatures vary with latitude ...
The figure on the left shows an example of monthly temperatures recorded in the city of Campinas, Brazil, which lies approximately 60 km north of the Tropic of Capricorn at 22 degrees latitude. Average yearly temperature is 22.4 °C, ranging from an average minimum of 12.2 °C to a maximum of 29.9 °C. The average temperature range is 11.4 °C ...
Every month a polar climate has an average temperature of less than 10 °C (50 °F). Regions with a polar climate cover more than 20% of the Earth's area. Most of these regions are far from the equator and near the poles , and in this case, winter days are extremely short and summer days are extremely long (they could last for the entirety of ...
