  "term": "Reynolds averaging",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical technique used in fluid dynamics to decompose a flow variable into a time-averaged mean component and a fluctuating component. This method simplifies the Navier-Stokes equations for turbulent flows by averaging them over a time scale much larger than the turbulent fluctuations but smaller than the mean flow changes. The resulting Reynolds-averaged Navier-Stokes (RANS) equations are widely used in atmospheric modeling and engineering applications.",
