Wind Chill Pill

Wind Chill Pill
To combat the cold and all the wind chill
There is a quest that I hope to fulfill
A formula I must first make stable
Then I’ll patent my great wind chill pill
So far the battle has been uphill
But I’ll keep on working on it until
I have a formula that fits the bill
To help mankind and spread goodwill
I have just learned of a plant in Brazil
Near a mountain on a secret foothill
There grows a rare plant, a cousin to dill
That I want to find, harvest and mill
Then its chemicals I hope to distill
But this itself takes some skill
It’s not like making a common swill
Do it wrong and this pill could kill
For now my plan is at a standstill
It’s just too cold to make a wind chill pill
-Mike Morrison

Bitterly cold temperatures and winds across much of the United States have given us dangerous conditions and have prompted wind chill alerts as far south as Florida.  

When cold air is motivated by wind it can cool surfaces at a much faster rate.  Wind Chill is a term we use to explain the cooling effects of cold air, combined with wind, on a person’s exposed skin. Surfaces including our exposed skin loses heat through conduction, convection and radiation. On exposed skin a warm insulation boundary of air will form near or close to the skin in cold air.  That boundary layer is disrupted in moving air allowing for cooler air to replace the warm air against the surface. The faster the wind speed, the more rapidly the surface cools.  

While the wind chill factor is always below the actual air temperature (where applicable) inanimate objects like metal or even skin will only cool to the temperature of the air.   For example if the air temperature is 32° with a 10mph wind will give a 23.7° wind chill temperature, objects in these condition will cool quicker but only to the actual air temperature.  

Wind chill factor can accelerate the onset of frostbite in cold conditions on exposed skin.  The most susceptible parts of the body are the extremities such as fingers, toes, ears, or  nose.  Medical attention is needed immediately for frostbite.
