  "term": "Minimum thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A specialized thermometer designed to record the lowest temperature reached over a specific time interval, such as overnight. It contains a small index marker within the alcohol column that is dragged down by the contracting liquid as the temperature falls. When the temperature rises, the alcohol expands past the index, leaving it at the lowest point, which is then read from the scale.",
