Relating to or denoting the component of a wind or current that arises from a balance between pressure gradients and Coriolis forces.
- ‘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.’
- ‘If a geostrophic wind, with pressure gradient force balanced by the Coriolis force, were to encounter a rough surface, the wind speed would decrease.’
- ‘Particle-related density gradients were responsible for roughly one-third of the geostrophic velocity shear at the plume edge.’
- ‘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.’
- ‘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.’
Early 20th century: from geo- of the earth + Greek strophē a turning (from strephein to turn).
