Wind chill index was first determined in an experiment in Antarctica over 50 years ago. It's very ancient. There's so much more new research available.

A chill wind is blowing in this nation.

It was 17 below wind chill. We were freezing the whole day.

Most experts agree that calculating wind chill gives a number too low. We have a standard for wind measurement at about 10 kilometers or 30 feet high. It's good for aviation use but it overestimates the wind speed. The wind down below is lighter (slower) than the wind at that height.

The ultimate aim is to get a set of options, as far as (that) community is concerned, about ways to express wind chill to the public. The big part of the workshop is changing how we calculate it and communicate it to the public.

That's all dependent on the wind and weather. Life in Antarctica is controlled by those two things.
