I've always been sort of amazed at how the atmosphere has largely "caught up" with the speed of the earth's surface.
What I mean is, at the equator isn't the surface of the earth moving at about 900kts?
So if the metar at KHNL is 090/15kts really the air is moving at maybe 815kts but we only experience the 15, because of the earth's ridiculous speed (numbers and +/- are approximate, this is about the concept).
Hey. Also - consider the surface of the earth is moving at 2x the speed of sound, where is my sonic boom, lol!
PS I know all these things can be explained away.
