  "term": "Filtered model",
  "field": "Meteorology and atmospheric science",
  "definition": "A numerical weather prediction model that employs filtered equations, designed to exclude or suppress high-frequency, small-scale atmospheric waves, such as sound waves and gravity waves. This approach allows for larger time steps in numerical integration, making the model more computationally efficient for simulating synoptic-scale weather. Early operational weather models were often filtered models.",
