Relating to or denoting the component of a wind or current that arises from a balance between pressure gradients and coriolis forces.
- ‘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.’
- ‘Particle-related density gradients were responsible for roughly one-third of the geostrophic velocity shear at the plume edge.’
- ‘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.’
- ‘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.’
Early 20th century from geo-‘of the earth’ + Greek strophē ‘a turning’ (from strephein ‘to turn’).
