![]() ![]() G'day,VinishYeah!!!! What he said.I knew rned it a way long time ago in thermal dynamics class. Which direction dominates depends on many variables such as amount of exposed skin, amount of sweat, relative humidity, and more. Hence, wind is a double-edged sword in hot weather. On a hot day - over 95 F - the wind is heating your body but at the same time, your sweat is being evaporated which cools your body and wind speeds up this evaporation which increases the rate of evaporative cooling. It's perceived as a reduction in the ambient air temperature due to the flow of air on your body. This is the cooling of the body by the evaporation of sweat. Conclusion People Also Ask How To Calculate Wind Chill On a Motorcycle What's The Best Temperature Level For Motorcycle Riding Why Does Wind Make You Cold The wind chill factor describes how chilly your body feels. There is another phenomenon occurring which is much more prevalent at higher air temperatures. The above analysis ONLY takes into account radiative, convective, and conductive heat transfer which are all that are considered in the concept of wind chill. Above skin temperature, the wind is heating us. This is shown as a "wind chill" which is the temperature at which the same amount of heat would be transferred in the absence of any wind. That is, it removes heat from our body surfaces faster or more efficiently. Higher wind speed makes the air cool us faster. When the air is below skin temperature (around 95 F), the air is cooling us. Wind merely increses the rate of heat transfer by reducing the thickness and effectiveness of the stagnant air layer next to the surface being heated or cooled. I perform heat transfer calculations for my job on an almost daily basis.
