South Pole,

southern end of the earth's axis, by convention at lat. 90° S. Because the earth's rotational axis wobbles slightly over time, the location where the southern end of the axis intersects the earth's surface shifts, although it is always within a few meters of the fixed geographic and cartographic position of the South Pole. It is distinguished from the south magnetic polemagnetic pole,
the two roughly opposite ends of the planet where the earth's magnetic intensity is the greatest, as the north and south magnetic poles. For the magnetic north, it is the direction from any point on the earth's surface linking the horizontal component of the

South Pole

 

the point at which the imaginary axis of the earth’s rotation intersects its surface in the southern hemisphere. All other points on the earth’s surface are north of the south pole. The south pole is situated on the continent of Antarctica, close to the Pacific coast at an elevation of 2,800 m. The ice in the vicinity of the south pole reaches a thickness of 2,810 m. The average annual air temperature for the period 1957–61 was –48.6°C, with a maximum of −14.7°C and a minimum of –78.9°C. The polar day lasts about 179 days, from September 23 to March 20–21 (not considering refraction). (See alsoPOLES, GEOGRAPHIC.)
