Today I have another question for you, thanks to Steve Cockerill of Rooster Sailing. We all know about "wind chill" which takes into account the combined cooling effect of air temperature and wind speed. But this doesn't adequately reflect the total chill experienced by us crazy frostbite sailors - in particular that invigorating feeling you get when a wave breaks over your head or icy spray slaps you in the face.
Steve says ...
I am trying to develop a new Chill Factor that takes into account the situation that dinghy sailors find themselves. Wind Chill takes into account the extra cooling effect of the air on bare skin and is only half of the equation. It does not take into account the additional cooling of water (a substance that can cool 27 times faster as it has a higher conductivity) or the dew point - a measure of how dry the surrounding air is (dryer air encourages water to evaporate, leaving you colder) and the water temperature.
So what do you think? How would we calculate a Spray Chill Factor?
In line with the high standards of scientific debate already established on this blog by the author (and others) do not allow your lack of qualifications to deter you from answering this question. If in doubt answer another but apparently similar question, provide links to dubious authorities who can't answer the question either, or indulge in gratuitous name-dropping. Go for it.
