  "term": "Polar maritime air",
  "field": "Meteorology and atmospheric science",
  "definition": "An air mass that originates over the polar oceans, characterized by cold temperatures and high humidity. As this air moves over warmer waters, it becomes unstable, leading to the formation of cumulus clouds and showery precipitation. This air mass frequently affects mid-latitude coastal regions, bringing cool, damp weather.",
