  "term": "Sling thermometer",
  "field": "Meteorology and atmospheric science",
  "definition": "A type of psychrometer used to measure atmospheric humidity, consisting of two thermometers, one dry-bulb and one wet-bulb, mounted together on a frame that can be whirled rapidly. The whirling motion provides adequate ventilation for the wet-bulb thermometer, promoting evaporation and cooling. The difference between the dry-bulb and wet-bulb temperatures is used to calculate relative humidity and dew point.",
