  "term": "Bred vectors",
  "field": "Meteorology and atmospheric science",
  "definition": "Perturbations to an atmospheric state that are repeatedly evolved forward in time by a numerical weather prediction model and then rescaled to a fixed amplitude. This process isolates the fastest growing instabilities in the model, which are then used to represent forecast uncertainty. They are a common technique for generating ensemble members in operational weather forecasting.",
