Nature: Antarctica: The End of the Earth: Katabatic

Documentary that explores Antarctica's weather phenomena, its rugged and adaptable wildlife and the powerful dynamics of its ever-changing icecap. Part 1 discusses the effects of the katabatic -- the relentless wind that sweeps over the Antarctic landscape, often at speeds of more than 100 mile per hour, re-sculpting the topography of the continent and affecting the climate of the entire southern hemisphere.
