it is because air sinks at the poles
High-Pressure region.
High Pressure
you would expect it to have high pressure
low
The North Pole generally experiences high air pressure due to the cold temperatures and the sinking air associated with colder regions. These conditions typically result in stable weather conditions with clear skies.
The South Pole is a low pressure region. Cold temperature areas tend to be low pressure while tropical regions are commonly high pressure.
The South Pole
in north pole
The winds always blow from the south at the South Pole due to the rotation of the Earth and the Coriolis effect, which causes the winds to flow from high pressure to low pressure areas. This is known as the polar easterlies.
low pressure
At the North Pole, wind direction can vary but is generally from the south due to the rotation of the Earth. This creates a circulation pattern where air moves from high pressure areas towards lower pressure areas, which can lead to southward winds at the North Pole.
High. From Wikipedia: "[The South Pole] sits atop a featureless, windswept, icy plateau at an altitude of 2,835 meters (9,306 ft), about 1,300 km (800 mi) from the nearest open sea at the Bay of Whales. The ice is estimated to be about 2,700 meters (9,000 ft) thick at the Pole, so the land surface under the ice sheet is actually near [or lower] than sea level."
