  "term": "Operator",
  "field": "Meteorology and atmospheric science",
  "definition": "A mathematical function or algorithm applied to data fields within a numerical weather prediction model to simulate a physical process. Operators represent discrete approximations of the differential equations governing atmospheric dynamics and physics, such as advection, diffusion, or pressure gradient forces. For example, a finite difference operator is used to calculate spatial derivatives of variables like temperature or wind speed on the model's grid.",
