Reduced gravity

  "id": "MLC-T-MET-008465",
  "term": "Reduced gravity",
  "field": "Meteorology and atmospheric science",
  "definition": "An approximation used in fluid dynamics for stratified fluids, where the full gravitational acceleration is replaced by a smaller, effective value. This effective gravity accounts for buoyancy forces between layers of different densities, such as a warm air mass over a cold one. The reduced gravity is calculated as g' = g(Δρ/ρ), where g is the standard gravitational acceleration, Δρ is the density difference between the layers, and ρ is a reference density.",
