  "term": "Rayleigh number",
  "field": "Meteorology and atmospheric science",
  "definition": "A dimensionless number that quantifies the ratio of buoyancy forces to viscous and thermal diffusive forces within a fluid. It is used to predict the onset of natural convection in a fluid layer heated from below. In atmospheric science, a critical Rayleigh number indicates when thermal convection will begin in a layer of air.",
