  1. Thunderstorm begins creating downward step leaders
  2. Ambient electric field intensity in the area of the ESE terminal increases
  3. Terminal is triggered to release the stored ground charge
  4. Upward streamer is formed microseconds earlier than other objects in the immediate area
  5. The TerraStreamer® ESE terminal becomes the target of the developing lightning strike
