  "term": "Ekman layer",
  "field": "Meteorology and atmospheric science",
  "definition": "A layer of fluid, either in the ocean or atmosphere, where the balance between the Coriolis force, pressure gradient force, and turbulent friction determines the velocity profile. In the atmosphere, it is the lowest part of the planetary boundary layer where surface friction significantly influences the wind direction and speed. The wind within this layer typically veers with height, forming an Ekman spiral.",
