Main Question or Discussion Point
You now how when you feel a light breeze it feels kind of cool? Why? Atoms are moving faster and they hit your skin with higher velocity so I would think wind would be hotter than normal.
If a surface is at a higher temperature then the surrounding air, then it heats the air that is close to the surface. For example, the air that touches the surface may be at the same temperature as the surface. There is a boundary layer near the surface where the temperature of the air and the temperature of the surface is nearly the same. Heat flow through that thermal layer will be much smaller than the heat flow that would result if the there was no thermal layers. The heated air near the surface acts a lot like an insulator.You now how when you feel a light breeze it feels kind of cool? Why?

This, by the way, is why things like styrofoam and rock wool are good thermal insulators. They capture air, which is a good insulator, and make it very difficult for it to move.“Air is an excellent insulator (R = 5.5/inch), as long as it does not move. It has poor conduction but good convection properties.”
