Wind has an enormous impact on cooling because of:
- increased evaporation (water absorbs vast amounts of heat when it evaporates - latent heat of evaporation)
- replacing warm air with colder air
In scientific language it can be referred to as forced convection, explained by Newton.
Interestingly, hot winds (when the air temperature is greater than your body temperature) will make you hotter than still air of the same temperature. This is why ovens equipped with fans cook food quicker.
The flight feathers of birds offer far greater wind resistance than fur and down. They are analogous to the woven outer fabric used in FurTech garments. Click here for more.
