Half-order closure

  "id": "MLC-T-MET-006152",
  "term": "Half-order closure",
  "field": "Meteorology and atmospheric science",
  "definition": "A simplified approach in atmospheric modeling to represent turbulent fluxes, where higher-order correlation terms are approximated using gradients of mean quantities. This method is less complex than full higher-order closures but more sophisticated than first-order closures. It is often used in boundary layer models to parameterize vertical transport of momentum and scalars.",
