isoneph
Very lowTechnical/Scientific
Definition
Meaning
A line on a map connecting points of equal cloud cover.
A contour line used in meteorology and climatology to represent areas with the same average amount of cloudiness over a given period, similar to how isobars connect points of equal pressure.
Linguistics
Semantic Notes
The term is highly specialized, used almost exclusively in meteorology and cartography. It's derived from Greek roots meaning 'equal' and 'cloud'. It is a hyponym within the broader category of isolines (contour lines).

Examples
By CEFR Level
- [This word is too advanced for A2 level]
- [This word is too advanced for B1 level]
- The meteorologist explained that the isonephs on the map showed where cloud cover was most consistent.
- By studying the isonephs, researchers could identify regions prone to prolonged overcast conditions.
- The climatological atlas featured detailed isonephs, revealing a clear gradient of decreasing cloudiness from the coast inland.
- Interpreting the isoneph patterns required an understanding of both synoptic weather systems and local topography.
Learning
Memory Aids
Mnemonic
Imagine a map where a line connects places that are equally NEPH-tunious (cloudy). Think: 'ISOlated NEPH (cloud) lines'.
Conceptual Metaphor
CONTOUR LINES ARE EQUALITY; CLOUD COVER IS A LANDSCAPE (mapped with contours).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изонить' (a thread graphics technique). The Russian equivalent is 'изонефа' (izonefa), but it is equally rare. Avoid direct translation attempts in non-scientific contexts.
Common Mistakes
- Mispronouncing as 'eye-so-neff' (stressing the second syllable).
- Misspelling as 'isoneph' or 'iso-neph'.
- Confusing it with 'isobar' (pressure) or 'isotherm' (temperature).

FAQ
Frequently Asked Questions
No, it is an extremely rare and specialized scientific term used almost exclusively in meteorology and cartography.
An isobar connects points of equal atmospheric pressure, while an isoneph connects points of equal cloud cover. Both are types of isolines.
It would be highly unusual and likely confusing. In everyday contexts, you would simply say 'areas with the same amount of cloud' or 'cloud cover lines on a map'.
In British English: /ˈaɪ.səʊ.nɛf/ (EYE-soh-nef). In American English: /ˈaɪ.soʊ.nɛf/ (EYE-soh-nef). The stress is on the first syllable.
