Barotropic vorticity equation

  "id": "MLC-T-MET-003835",
  "term": "Barotropic vorticity equation",
  "field": "Meteorology and atmospheric science",
  "definition": "A simplified form of the vorticity equation that describes the evolution of absolute vorticity in a two-dimensional, incompressible, and inviscid fluid. This equation assumes that density depends only on pressure, meaning there are no horizontal temperature or density gradients. It is often used to model large-scale atmospheric flows where vertical variations are negligible, such as in forecasting the movement of longwaves in the upper troposphere.",
