WebNo. Air friction does not do that. A hot object can transfer heat to the air by conduction (the object touches the air), and by convection (as the heated air rises, cool air takes its place), and probably by radiation as well.

On a slope, air rushes in more easily from the downhill than the uphill side. If the slope is sufficiently steep, all of the air may come in from the downhill side, pushing the flames into the slope and putting them in contact with more fuel. earthquake in central virginia today
