  "id": "MLC-T-MET-009899",
  "term": "Unstable channel",
  "field": "Meteorology and atmospheric science",
  "definition": "A conceptual region or flow within the atmosphere characterized by dynamic conditions that cause small disturbances to amplify into larger-scale weather systems. Such instability can be baroclinic, driven by horizontal temperature gradients, or barotropic, resulting from shears in the horizontal wind field. The development of mid-latitude cyclones is a classic example of baroclinic instability occurring within the westerly wind channel.",
