Definition

1. Noun:
   • A recording barometer; an instrument that automatically records variations in atmospheric pressure on paper: A "barograph" is a scientific instrument used in meteorology. It consists of a barometer connected to a pen that marks a continuous line on a rotating drum of paper, creating a permanent chart (a barogram) of pressure changes over time.

Usage

• Noun:
  • The ship's navigator checked the barograph to see the recent trend in atmospheric pressure.
  • Old weather stations often used a barograph to produce a daily pressure trace.
  • The steady fall shown on the barograph chart was a clear sign of the approaching storm.

Advanced Usage

• "Barograph trace" or "barogram": Refers to the specific paper chart produced by the instrument.
  • The meteorologist analyzed the barograph trace from the previous 24 hours.
• In professional contexts, a barograph is a key tool for forecasting, as pressure trends are more significant than a single pressure reading.

Variants and Related Words

• Barogram (n): The chart or record produced by a barograph.
• Barometer (n): An instrument for measuring atmospheric pressure. A barograph is a specific type of recording barometer.
• Barographic (adj): Relating to or using a barograph.

Related Phrases and Terms

• Aneroid barograph: A common type that uses a sealed, flexible metal box (an aneroid cell) instead of liquid to sense pressure changes.
• Mercury barograph: A less common type that uses a mercury barometer as the sensing element.
