WebApr 11, 2024 · Geostrophic Motion Meaning. Geostrophic motion is a fluid flow that occurs in a direction parallel to the lines of equal pressures/isobaric in a rotating system, such as the Earth. A Geostrophic flow occurs by the balance of the Coriolis force (a force caused by the Earth’s rotation), and the pressure-gradient force (when the friction is low). scotty raye

In atmospheric science, geostrophic flow is the theoretical wind that would result from an exact balance between the Coriolis force and the pressure gradient force. This condition is called geostrophic equilibrium or geostrophic balance (also known as geostrophy). The geostrophic wind is directed parallel to isobars (lines of constant pressure at a given height). This balance seldom holds exactly in nature. The true wind almost always differs from the geostrophic wind due to ot… Webthe observed wind vector (one full quiver represents a wind speed of 5 ms−1).
