barotropy
Very Rare / SpecializedTechnical / Scientific
Definition
Meaning
A state of a fluid where its density depends solely on pressure.
In meteorology and fluid dynamics, a state or condition where surfaces of constant pressure and constant density are parallel. More broadly, any system or condition where a property (like density) is a function of pressure alone.
Linguistics
Semantic Notes
Primarily used as a noun describing a physical state. It is an abstract, theoretical concept, not a tangible object. The related adjective is 'barotropic.' The opposite concept is 'baroclinicity.'
Dialectal Variation

Examples
By Part of Speech
adjective
British English
- The fluid is assumed to be barotropic for this simplified model.
American English
- A barotropic atmosphere simplifies the forecast equations considerably.
Examples
By CEFR Level
- 'Barotropy' is a highly technical term from fluid physics.
- The classic model assumes barotropy, meaning density varies only with pressure, which eliminates certain complex wave interactions.
- In a state of barotropy, the geostrophic wind does not change with height.
Learning
Memory Aids
Mnemonic
Imagine a BARO-meter measuring PRESSURE, and a TROPY (sounds like 'trophy') you get when density is only a function of that pressure.
Conceptual Metaphor
A UNIFORM ARMY: All fluid parcels (soldiers) are organized strictly by their pressure rank (military rank), with no other factors like temperature causing internal divisions.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'barotrauma' (баротравма).
- The '-tropy' suffix relates to 'turning' or 'condition,' not directly to 'тропики' (tropics).
- The adjective 'barotropic' (баротропный) is more common than the noun.
Common Mistakes
- Misspelling as 'baratropy' or 'barotropy'.
- Using it as an adjective (the adjective is 'barotropic').
- Confusing it with 'baroclinic' (its opposite).

FAQ
Frequently Asked Questions
It is used in geophysical fluid dynamics and meteorology to describe an idealized state of a fluid where density depends only on pressure, simplifying the mathematical equations.
No, it is an extremely specialized scientific term unlikely to be encountered outside advanced academic or technical contexts in fields like physics or atmospheric science.
The opposite state is 'baroclinicity' or a 'baroclinic' state, where density depends on both pressure and temperature (or other factors), leading to more complex fluid motions.
No, the noun is 'barotropy'. The corresponding adjective is 'barotropic' (e.g., a barotropic fluid, a barotropic model).
