  "id": "MLC-T-MET-003881",
  "term": "Beltrami flow",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of fluid flow where the velocity vector is everywhere parallel to its own vorticity vector. This means that the streamlines and vortex lines are aligned, indicating a helical motion of the fluid. In atmospheric science, Beltrami flows are sometimes used as idealized models for certain types of atmospheric vortices or helical structures in fluid dynamics.",
