  "id": "MLC-T-MET-007573",
  "term": "Nondimensional number",
  "field": "Meteorology and atmospheric science",
  "definition": "A quantity without any physical units, created by combining physical variables in such a way that all units cancel. These numbers simplify the analysis of complex physical systems by reducing the number of independent variables needed to describe them. Examples in atmospheric science include the Reynolds number, which characterizes flow regimes, and the Richardson number, which indicates dynamic stability.",
