  "term": "Identical twin integrations",
  "field": "Meteorology and atmospheric science",
  "definition": "A method used in numerical weather prediction and climate modeling to assess the predictability of the atmosphere or the sensitivity of a model to small perturbations. Two simulations are run, one considered the 'truth' and the other initialized with a very small, often imperceptible, difference. The divergence between the two simulations reveals the inherent predictability limits or the impact of initial condition errors.",
