Autumn marks the beginning of the six-month period in which the sun remains below the horizon. Antarctica only has winter and summer. Since there is no vegetation to speak of, there is no means by which to delineate seasons like autumn and spring. Because Antarctica is a "polar" region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months. The coastal temperatures are much warmer with a range of -15 to -32 Celsius in Winter and -5 to +5 Celsius in Summer. The interior of Antarctica is considered the world's driest desert because the extreme cold freezes water vapour out of the air. Annual snowfall on the polar plateau is equivalent to less than 5 cm of rain. Antarctica has some of the strongest winds on earth, with some winds reaching 320 kph.
