The two are totally unrelated. Wind chill is an attempt to quantify
the effect wind has on the perception of temperature by humans. It
does not take humidity into account. The wind chill would be the
same whether the RH was 0 or 100%. The sling pyschrometer or swamp
cooler have slightly different dependencies on humidity.
A decent idea when conceived, wind chill has turned into little more
than something the TV weather idiots can scream about. Being a
subjective scale, it has little to do with science.

This will be news to the wet bulb thermometer and those using
evaporative coolers.

John!, John!, JOHN you are over your head on this one.

13. Does humidity or being near a large water body affect on wind chill?
When we tested the new Wind Chill Temperature Index (WCTI), our researchers
applied the new index to 12 test subjects. The results of the tests showed
that relative humidity was an insignificant weather parameter, less than one
degree at worst. To simplify the calculation, relative humidity was left out
of the formula.
We did research a wet wind chill or blowing water spray. This research was
to simulate a person near a body of water or a mariner. These findings are
being finalized and may be incorporated for the winter season 2003-2004.
They tested seeding the clouds too, that proved flawed as well. If
humidity does not have any thing to do with wind chill why cant you
cool dry air? Why do they use swamp coolers in dry areas?
