Air currents of any kind, atmospheric or otherwise, do not normally have any color nor can they be assigned a sex, although an air current may contain odors, or smoke, or clouds that have various colors in some circumstances (often red during the two twilights occurring each day). Right element's original meaning is「sex, color, and the color of sex, turning red」referring to elements of「head and neck with screwing vortex, vagina, penis with flesh seam within orifice.」Left element of a「virgin's vulva spread to reveal the central portion」due to having「sex」may naturally break most of the remaining hymen attached to the sides of the vaginal opening into tissue tags, and cause some red color to appear, that of blood, with its telltale smell. …so, putting this all together suggests that after having sex initially and losing one's virginity, the central portion of the vulva will now be exposed to AIR FLOW, or if you insist, to AIR CURRENTS IN THE ATMOSPHERE, a meaning ascribed by external sources that seems to grossly exaggerate the conditions described with the intention of obfuscating the point made by the glyph's elements, which instead may be describing that unique odor of clouded blood mixed with vaginal mucus and semen which occurs upon the deflowering of a female virgin, one of the favorite pastimes of lords and emperors, WAFTING OFF TO SOME DIVINE PLACE IN HEAVEN. Then again, perhaps the meaning is that the「central part of sex」is a blow job, as is depicted by many, many other glyphs. It should be pointed out that the only source meaning located was one not listed in our source Chinese dictionary, hence some modern assumptions may be at play, and the Chinese prefer not to provide their historical meaning, for some reason that can only be guessed. Japanese pronunciations sometimes are helpful, but they too are missing: nonetheless, COLORFUL SEX with CENTER OF VULVA, or, PERFORMING A DEFLOWERING, do seem to fit the ascribed external meaning.
