Spectral model

  "id": "MLC-T-MET-009106",
  "term": "Spectral model",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of numerical weather prediction model that represents atmospheric variables as a sum of basis functions, typically spherical harmonics, rather than on a grid. This approach efficiently handles global domains and avoids certain numerical artifacts associated with grid-point models. The resolution of the model is determined by the maximum wavenumber included in the expansion.",
