I once asked Environment Canada for the formula so I could calculate the equivalent
temperature.
The instead sent me a small program that does it for me and a note saying that they
are coming up with a new system to calculate windchill since (if memory serves me
right) it was originally determined by measuring the heat loss in buckets of water in
the Antarctic.
That's all I know.

Did anyone see the Monday, 2000-12-18 issue of the Wall Street Journal? The
front page article entitled: "First Santa Claus, Now The Wind chill Is
Called Into Question". Scientists look for a New Index Everybody Can
Believe In; The One We Use Is Wrong
The article was written by Mark Robichaux, Staff Reporter.
It gives the history of how wind chill was first determined. Talks about
how it is done in Canada and other countries. But, only mentions that
Canada uses Watts per square metre as a measure of heat loss. The US uses
equivalent temperatures. Either methods are in error because the formula
for doing the calculation is in error.
There is suppose to be a world-wide effort to come up with a new index. The
new method will be announced in Geneva early next fall. The article says
nothing of what units the new method would use. If I were to guess, the
watt per square metre would continue, but the calculation method would be
improved.
But, something tells me the Americans will mess it all up by trying to find
an FFU equivalence.
Has anyone else heard anything more on this subject?
