  "term": "Weighting",
  "field": "Meteorology and atmospheric science",
  "definition": "The application of numerical coefficients to a set of data points to assign them different degrees of influence on a summary statistic. In ensemble forecasting, different model runs may be weighted based on their past performance or other factors before being combined into a single forecast. For example, a model with a better historical track record for a specific region might receive a higher weight than other models in the ensemble.",
