Definition
Meaning and Definition
A wind generated by the downward flow of cold, dense air under the influence of gravity, typically down a slope from a higher elevation.
In meteorology, a katabatic wind: drainage wind flowing downhill due to its higher density than the surrounding air, caused by surface cooling (e.g., over ice sheets or at night). In some informal contexts, used metaphorically for any powerful downward force or influence.
Dialectal Variation
British vs American Usage
Differences
Both use the term identically in scientific contexts. No spelling or lexical differences.
Connotations
Purely technical term with no divergent connotations.
Frequency
Equally rare and specialized in both dialects, used almost exclusively within meteorology, geography, and related earth sciences.

Common Mistakes When Using “gravity wind”
- Confusing 'gravity wind' (cold, dense air flowing down) with 'anabatic wind' (warm air flowing up). Using it as a general synonym for 'strong wind'. Misspelling as 'gravity-wind' (hyphenation is not standard).
FAQ
Frequently Asked Questions
Yes, 'gravity wind' is essentially a synonym for 'katabatic wind', though 'katabatic' is the more precise and commonly used scientific term.
They are most pronounced in regions with significant, cold elevated surfaces, such as Antarctica, Greenland, and large mountain glaciers, especially on clear nights.
No, by definition, it is generated by air that is denser (and therefore colder) than the air it displaces. However, the adiabatic compression as it descends can sometimes warm it slightly, but its origin is always relatively cold.
A regular breeze is driven by horizontal pressure differences. A gravity wind is driven primarily by vertical density differences and the force of gravity acting on those dense air masses.
A wind generated by the downward flow of cold, dense air under the influence of gravity, typically down a slope from a higher elevation.
Gravity wind is usually technical (meteorology, physical geography); scientific in register.
