When people say, about the weather, “It’s close out”, meaning, “It’s humid”, it’s because some things, in a relative way, actually are closer.
Deep sounds, with longer wavelengths, like a rumbling train; and “base note” smells, with larger molecules, like the mercaptans of cigarette smoke, are – relative to our ‘normal’ range of distal perception – closer to us, because they can travel more easily on the excess moisture in the air.
