whirlwind, cyclone, floating
飃 centers on violent, rotating wind: a whirlwind or cyclone. The floating sense extends from the idea of being carried or tossed by such a wind.
飃 combines 風 (wind) with 票, which likely contributes the sound. The character is a variant form of 飄, where 票 is used phonetically to express whirling wind.
The wind enclosure 風 wraps around 票, like a ticket being spun and tossed by a cyclone. Picture a whirlwind carrying floating tickets in a spiral.
For ヒョウ, imagine a whirlwind lifting a hyō (雹, hailstone) into the air: hyō -> ヒョウ, and the floating hail spins inside the wind.
