  "id": "MLC-T-MET-006628",
  "term": "Invasion of air",
  "field": "Meteorology and atmospheric science",
  "definition": "The advection of an air mass with distinct thermal and moisture properties into a region previously occupied by a different air mass. This process leads to changes in local weather conditions, such as temperature, humidity, and stability. For example, a cold air invasion brings colder, drier air, often resulting in a drop in temperature and clear skies.",
