Windchill in Antarctica is the same phenomenon as windchill
anywhere on earth: the ambient temperature plus the wind speed,
determine the windchill temperature.
Antarctica is the windiest continent on earth, it is also the
coldest continent on earth. With ambient temperatures colder than
minus 100 degrees F, and wind speeds up to almost 200 MPH,
depending on where you are on the continent, the windchill
temperature is cold, very cold or very, very cold.
Windchill in Antarctica can be lethal.
