Eddy diffusivity

  "id": "MLC-T-MET-005272",
  "term": "Eddy diffusivity",
  "field": "Meteorology and atmospheric science",
  "definition": "A measure of the rate at which turbulent eddies transport momentum, heat, or constituents within a fluid. It quantifies the mixing efficiency of turbulence, analogous to molecular diffusivity but on a much larger scale. This parameter is often used in atmospheric models to represent sub-grid scale turbulent mixing processes.",
  "synonyms": [
    "coefficient of eddy diffusion",
