barometric pressure
C1Technical, Academic, Weather Reporting
Definition
Meaning
The pressure exerted by the weight of the atmosphere at a given point, measured by a barometer.
The atmospheric pressure at a given location, used to predict weather changes; lower pressure typically indicates storms or rain, while higher pressure indicates fair weather.
Linguistics
Semantic Notes
This is a compound scientific term. Its meaning is fixed and technical, with little room for figurative use. It specifically refers to the physical measurement, not a general sense of 'atmospheric pressure'.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. In everyday US weather reports, 'pressure' is often used alone.
Connotations
Identical technical connotations.
Frequency
Slightly more frequent in UK weather reports, where the full term 'barometric pressure' is more commonly stated. US reports often say 'the pressure is falling/rising'.

Usage
Context Usage
Business
Rare, except in industries like aviation, agriculture, or outdoor events planning where weather is a critical factor.
Academic
Common in meteorology, geography, physics, and environmental science texts.
Everyday
Primarily in weather forecasts, conversations about hiking, sailing, or when people with conditions like arthritis discuss weather changes.
Technical
The primary context; precise measurements and trends are discussed in aviation, shipping, and scientific research.
Examples
By Part of Speech
verb
British English
- The instrument is used to barometrically pressure the column of mercury.
- Systems are designed to barometric-pressure the sensor.
American English
- The device barometric-pressures the atmosphere for a reading.
- We need to barometric pressure the local environment.
adverb
British English
- The reading changed barometrically-pressure-wise.
- The system functions barometric-pressure-ly.
American English
- The data was recorded barometric-pressure-ly.
- It fluctuated barometrically in terms of pressure.
adjective
British English
- The barometric-pressure reading was crucial.
- They studied the barometric-pressure changes.
American English
- The barometric pressure chart showed a clear trend.
- He felt a barometric pressure headache coming on.
Examples
By CEFR Level
- The weather changes with barometric pressure.
- High barometric pressure means sunny weather.
- The pilot checked the barometric pressure before takeoff.
- My grandfather says he can feel the barometric pressure drop in his knees.
- A rapid fall in barometric pressure is often a precursor to severe storms.
- Fishermen pay close attention to barometric pressure trends to predict fish activity.
- The research correlated migraine incidence with fluctuations in barometric pressure.
- Isobars on a weather map connect points of equal barometric pressure, revealing pressure gradients and wind patterns.
Learning
Memory Aids
Mnemonic
Imagine a BAR with a METER on it. The BAR-O-METER measures the weight (PRESSURE) of the air above you, like a column pressing down.
Conceptual Metaphor
The atmosphere as a fluid with weight; pressure as a force/push (e.g., 'high pressure building in').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque 'барометрическое давление' in non-technical contexts; 'атмосферное давление' is more common in general Russian.
- The English term is more specific than the general Russian 'давление' (which can mean blood pressure, peer pressure, etc.).
Common Mistakes
- Pronouncing it as 'barometric-al pressure'.
- Using 'barometer pressure' (incorrect noun-noun compound).
- Confusing it with 'blood pressure' in rapid speech.

FAQ
Frequently Asked Questions
In most practical contexts, yes. However, 'barometric pressure' specifically refers to pressure measured by a barometer, often adjusted to sea level, while 'atmospheric pressure' is the broader scientific term.
The leading theory is that changes in pressure can cause expansion and contraction of gases and fluids in the sinuses and joints, triggering pain receptors, particularly in people prone to migraines or arthritis.
Common units include hectopascals (hPa), millibars (mb), inches of mercury (inHg), and millimeters of mercury (mmHg). Hectopascals and millibars are numerically equivalent.
In weather contexts (e.g., 'the pressure is falling'), yes. In other contexts (medical, engineering), 'pressure' alone is ambiguous and should be specified.
