The South Pole is at an altitude of about 2835m (9306ft), so the concept of 'surface currents' needs to be considered. The air from the upper atmosphere is very cold, and descends at the Polar Plateau, and from there descends by gravity to the coast.

At Dumont d'Urville station on the coast, the katabaticwind has reached over 300 km/h and 150 km/h is pretty common. Many of the base buildings are buried to minimise the effect of wind.

Vostok Station has an average wind run of 18km/h, and its altitude is 3488m. The air is thin, cold, and extremely dry.
