What does barometry mean?
Barometry is the science and measurement of atmospheric pressure, the force exerted by the weight of air on a given area. It is closely associated with meteorology because changes in pressure can indicate approaching storms, shifting winds, or improvements in the weather. Accurate barometry depends on careful instrument calibration, consistent observation, and an understanding of how atmospheric conditions vary with altitude and temperature. The word is also occasionally used figuratively for indicators of wider conditions or trends, although this extension is less common in everyday language. As a field, barometry helped transform weather observation by making invisible changes in the atmosphere measurable. Today, digital pressure sensors and satellite data support modern forecasting, but the basic principle remains the same: atmospheric pressure provides important evidence about the state and future development of the weather.
nounThe science or measurement of atmospheric pressure, especially as a means of observing weather and atmospheric changes.
- The measurement or study of atmospheric pressure, especially in relation to weather.
"Meteorologists use barometry to track changes in atmospheric pressure."
"Meteorologists use barometry to track changes in atmospheric pressure."
"The mountain station's barometry showed a steady fall in air pressure."
The plural is grammatically possible but rare because barometry is usually used as an uncountable noun.
"The archive contains barometries from several historic expeditions."
A barometer makes the invisible weight of air visible in a single needle—and barometry is the science behind the reading.

Where does barometry come from?
Barometry was formed in English from Greek baros, meaning “weight,” and metron, meaning “measure.” The same roots underlie barometer, the instrument that measures atmospheric pressure, and related scientific terms such as barometric and barography. The compound developed as the name for the measurement of atmospheric pressure and became closely linked with the development of systematic meteorological observation.

How barometry is actually used
Primarily formal and scientific. Figurative uses for gauging trends are uncommon and can sound compressed or unusual in ordinary conversation.
Easily confused with barometry
Barometry is the measurement or study of atmospheric pressure, whereas a barometer is the instrument used to measure it.
