  "id": "MLC-T-MET-007042",
  "term": "Long-train atmospherics",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of radio atmospheric disturbance characterized by a series of closely spaced, distinct electromagnetic impulses that persist for an extended duration. These signals are generated by lightning discharges and propagate through the Earth-ionosphere waveguide. They are often observed as a 'train' of static on radio receivers, particularly in the VLF (Very Low Frequency) range.",
