Brit.

/ˌeɪdʒiːəˈstrɒfɪk/,

/ˌeɪdʒiːəˈstrəʊfɪk/, U.S.

/ˌeɪˌdʒiəˈstrɑfɪk/

Origin: Formed within English, by derivation. Etymons: a- prefix⁶, geostrophic adj.

Etymology: < a- prefix⁶ + geostrophic adj.

Meteorology.

Not geostrophic (geostrophic adj.); spec. designating the wind component which when added to a geostrophic wind gives the actual wind.
