  "term": "Dry adiabat",
  "field": "Meteorology and atmospheric science",
  "definitions": [
    "A line on a thermodynamic diagram representing the temperature change of an unsaturated parcel of air as it rises or sinks adiabatically. As dry air rises, it expands and cools at a constant rate due to the decrease in atmospheric pressure, without exchanging heat with its surroundings. This cooling rate is approximately 9.8 degrees Celsius per 1000 meters.",
    "A line of constant potential temperature on a thermodynamic chart."
