Low frequencyTechnical, formal
Definition
Meaning
A barometer that automatically records its readings on a moving chart over time.
A meteorological instrument used for creating a continuous chart (barogram) of atmospheric pressure, allowing for the analysis of trends and forecasting.
Linguistics
Semantic Notes
The term is a combination of 'baro-' (pressure) and '-graph' (recording instrument). It implies an automatic recording mechanism, distinguishing it from a simple visual barometer. It belongs to the same semantic field as 'thermograph' and 'hygrograph'.

Examples
By CEFR Level
- A barograph is a weather instrument.
- It draws a line on paper.
- The ship's captain checked the barograph for changes in pressure.
- A falling line on the barograph chart often means stormy weather is coming.
- Meteorologists use barographs to create a continuous record of atmospheric pressure, which is crucial for weather forecasting.
- The antique aneroid barograph, with its clockwork mechanism, was still functioning perfectly.
- Analysis of the barograph trace revealed a series of microbarographs, indicating the passage of a mesoscale convective system.
- The barograph's sensitivity had to be calibrated to filter out minor pressure oscillations caused by local wind effects.
Learning
Memory Aids
Mnemonic
Imagine a BAR where the air pressure is GRAPHed on the wall. A BAROGRAPH graphs pressure at the bar.
Conceptual Metaphor
A PRESSURE DIARY or a PRESSURE SCRIBE.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'барограф' (direct translation is correct). Do not confuse with 'барометр' (barometer), as a барометр may not record data automatically.
Common Mistakes
- Misspelling as 'barogragh' or 'barograph'. Using it as a general term for any barometer. Incorrectly assuming it is a common household item.

FAQ
Frequently Asked Questions
A barometer measures atmospheric pressure at a given moment. A barograph is a type of barometer that automatically and continuously records those measurements on a chart over time.
Barographs are typically found in weather stations, on ships, in aviation contexts, and sometimes in the homes of weather enthusiasts or collectors of scientific instruments.
No, it is a low-frequency, specialized technical term. Most people would use the more general term 'barometer' unless they specifically need to refer to the recording feature.
Yes. Traditional barographs use a pen on a rotating drum of paper (analogue), but modern versions often record data digitally, though the term 'barograph' is still applied to both types.
