whirlwind, stormy gale
飇 centers on a violent, spiraling wind: a whirlwind or a stormy gale. Both meanings describe the same intense, rotating wind phenomenon.
飇 combines 風 (wind) with 猋, which likely contributes both sound and the idea of rushing or swirling, as 猋 itself suggests a pack of dogs running swiftly. Together they express a violent, swirling wind.
The wind radical 風 wraps around 猋, which looks like three dogs (犬) running in a frenzy. Picture a whirlwind so fierce it's like a pack of dogs chasing their tails inside a storm.
For ヒョウ, imagine a whirlwind so strong it makes a 'hyow' sound as it spins: hyow -> ヒョウ, the stormy gale howling.
