  "id": "MLC-T-MET-010066",
  "term": "Vortex stretching",
  "field": "Meteorology and atmospheric science",
  "definition": "The process by which a vortex tube or filament becomes elongated, leading to an increase in its rotational velocity and a corresponding intensification of vorticity. This phenomenon occurs when fluid parcels within the vortex are stretched along the axis of rotation. Vortex stretching is a key mechanism in the formation and intensification of tornadoes and other strong atmospheric circulations.",
