Antarctica is the coldest place on Earth. It is a frozen desert with little [[precipitation (meteorology)|precipitation]]; the South Pole itself receives almost none. Temperatures reach a minimum of between −85&nbsp;°C and −90&nbsp;°C (−121&nbsp;°F and −130&nbsp;°F) in the winter and about 30&nbsp;degrees higher in the summer months. Sunburn is often a health issue as the snow surface reflects over 90% of the sunlight falling on it.<ref name="weather">British Antarctic Survey. [http://www.antarctica.ac.uk/met/jds/weather/weather.htm ''Weather in the Antarctic''] Retrieved [[February 9]] [[2006]].</ref> Eastern Antarctica is colder than its western counterpart because of higher elevation. [[Weather front]]s rarely penetrate far into the continent, leaving the center cold and dry. Despite the lack of precipitation over the central portion of the continent, [[ice]] there lasts for extended time periods. Heavy snowfalls are not uncommon on the coastal portion of the continent, where snowfalls of up to 1.22&nbsp;meters (48&nbsp;inches) in 48&nbsp;hours have been recorded. [[Акс:Friesland-St-Boris.jpg|210px|thumb|right|Mountain glaciation.]] At the edge of the continent, strong [[katabatic wind]]s off the polar plateau often blow at storm force. In the interior, however, wind speeds are typically moderate. During summer more [[solar radiation]] reaches the surface at the South Pole than is received at the [[equator]] in an equivalent period.<ref name="cia" />
