Definition of geostrophic in English:

geostrophic

adjective ˌdʒiːə(ʊ)ˈstrəʊfɪkˌdʒiːə(ʊ)ˈstrɒfɪkˌjēəˈsträfik
Meteorology Oceanography
  • Relating to or denoting the component of a wind or current that arises from a balance between pressure gradients and coriolis forces.

    〔气象,海洋学〕地转(性)的

    Example sentencesExamples
    • If a geostrophic wind, with pressure gradient force balanced by the Coriolis force, were to encounter a rough surface, the wind speed would decrease.
    • In addition to these local variables, a regional indicator of geostrophic wind, calculated from daily air pressure measurements at three stations in northwestern Germany, was used.
    • The time scales of vertical transport through the water column are likely to be too short for significant geostrophic and baroclinic modification of the vertical density currents themselves.
    • My dry bulb temperature reading was looking good, but we all knew that if the geostrophic wind were to grow, it would pour down for sure.
    • Particle-related density gradients were responsible for roughly one-third of the geostrophic velocity shear at the plume edge.

Origin

Early 20th century: from geo- 'of the earth' + Greek strophē 'a turning' (from strephein 'to turn').
