  "id": "MLC-T-MET-009902",
  "term": "Unsteady flow",
  "field": "Meteorology and atmospheric science",
  "definition": "Fluid motion where the velocity, pressure, or other flow properties at a given point change with time. In meteorology, this describes atmospheric or oceanic currents that are not constant, exhibiting variations in speed or direction over a period. Most atmospheric flows are inherently unsteady, driven by diurnal cycles, synoptic weather systems, and turbulent eddies.",
