Let's take mount washington. it's a very cold place, holding many records for lowest temperature and highest wind speed in north america.
let's take a moderately cold temperature, say...a balmy -65F, and a wind speed of around 100mph (normal for the mountaintop)
that equates to a LETHAL -140F wind chill.
When I was in Boston on the New Year's eve,last day of 1996,the windchill was -40 in boston
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.
