Oroshi (颪, lit, down wind) is the Japanese term for a wind blowing strong down the slope of a mountain, occasionally as strong gusts of wind which can cause damage. Oroshi is a strong local wind across the Kanto Plain on the Pacific Ocean side of central Honshu. This term identifies a katabatic wind.
Many versions of this poem which were published during the Edo period have yama-oroshi instead of yama-oroshi yo, but the meaning is equivalent: the poet cries out to the wind; and he the cold down-draft to the heartless woman.
