Collision theory

  "id": "MLC-T-MET-004517",
  "term": "Collision theory",
  "field": "Meteorology and atmospheric science",
  "definition": "A theory explaining the growth of cloud droplets into raindrops through the process of collision and coalescence. It posits that larger cloud droplets, falling faster than smaller ones, collide with and absorb the smaller droplets, increasing their mass and eventually leading to precipitation. This mechanism is particularly effective in warm clouds where temperatures are above freezing, and it is a primary pathway for rain formation in tropical regions.",
