'wind-related' originates from modern English compounding of the noun 'wind' and the adjective 'related'; 'wind' refers to moving air and 'related' is the past-participial adjective from 'relate' meaning 'to connect'.

'wind' comes from Old English 'wind' (meaning moving air). 'Related' is formed from the past participle of 'relate' (via Middle English and Old French from Latin roots), and the compound 'wind-related' is a recent English formation combining the two words into a descriptive adjective.

Initially the components were separate words ('wind' and 'related'); over time they have been combined productively in modern English to form a compound adjective meaning 'connected with or caused by wind'.
