Geostrophic flow

  "id": "MLC-T-MET-005952",
  "term": "Geostrophic flow",
  "field": "Meteorology and atmospheric science",
  "definition": "An idealized horizontal flow in a rotating fluid, such as the atmosphere or ocean, where the Coriolis force perfectly balances the horizontal pressure gradient force. This balance causes the fluid to move parallel to the isobars (lines of constant pressure). Geostrophic flow is a good approximation for large-scale motions away from the equator and frictional boundaries, and it is a cornerstone of dynamic meteorology.",
