Field strength

  "id": "MLC-T-MET-005567",
  "term": "Field strength",
  "field": "Meteorology and atmospheric science",
  "definition": "The magnitude of the electric field vector at a specific point in the atmosphere, representing the force that would be exerted on a unit of electric charge. It is created by the net separation of electric charges between the ionosphere and the Earth's surface, and locally by charge separation within clouds. The fair-weather atmospheric electric field near the ground is around 100 volts per meter, but it can increase to tens of thousands of volts per meter and reverse polarity beneath a thunderstorm.",
