  "term": "Cascade shower",
  "field": "Meteorology and atmospheric science",
  "definition": "A phenomenon in the upper atmosphere where a high-energy cosmic ray particle interacts with atmospheric nuclei, producing a shower of secondary particles. These secondary particles, primarily electrons, positrons, and photons, then generate further particles through successive interactions. This process contributes to the background radiation levels at high altitudes.",
