'astrometeorological' originates from Greek elements via Modern Latin/English formation, specifically Greek 'astron' and 'meteōron', where 'astron' meant 'star' and 'meteōron' meant 'thing high in the air' (used for phenomena observed in the sky).

'astrometeorological' developed from the noun 'astrometeorology' (a compound of 'astro-' + 'meteorology') and then formed into the adjective by adding the English adjectival suffix '-ical'. The compound itself reflects a 19th-century tendency to combine classical elements in scientific terminology.

Initially, the term was tied to attempts to predict weather from celestial observations; over time it has come to mean generally 'relating to astrometeorology' and is now mainly used descriptively or historically (sometimes with a connotation of pseudo‑scientific practice).
