synoptic chart
C2/ProficiencyTechnical/Specialist
Definition
Meaning
A meteorological map that shows weather conditions over a large area at a specific time, using standardized symbols for fronts, pressure systems, and other phenomena.
Any chart or diagram that presents a summary view of complex data or a situation at a given point in time, though this use is rarer and often metaphorical. The term is predominantly technical and meteorological.
Linguistics
Semantic Notes
A 'synoptic chart' is a snapshot summary, not a forecast. It is the basis for forecasting. The 'synoptic' part relates to 'synopsis' (summary). It is a hyponym of 'weather map'.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is standard in meteorological communities in both regions.
Connotations
Purely technical and neutral in both varieties.
Frequency
Equally low-frequency in general language but standard within meteorology. In everyday contexts, 'weather map' is far more common in both the UK and US.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct translation of 'synoptic' as 'синоптический' in non-weather contexts. In English, it is almost exclusively meteorological in this collocation.
- Do not confuse with 'synthetic chart' – 'synoptic' is about observation summary, not synthesis.
Common Mistakes
- Pronouncing 'synoptic' as /ˈsaɪnəptɪk/ (like 'synopsis' can be mispronounced).
- Using it as a general term for any summary chart outside of meteorology.
- Confusing it with a 'forecast map'.

What is the primary purpose of a synoptic chart?
FAQ
Frequently Asked Questions
Yes, but it is a specific, technical type of weather map. All synoptic charts are weather maps, but not all weather maps (e.g., simple temperature maps) are technically synoptic charts, which emphasize pressure systems and fronts.
It would sound very technical. In everyday speech, 'weather map' is the appropriate and universally understood term.
In professional meteorology, standard surface synoptic charts are typically produced every 3 to 6 hours based on data from a specific observation time (e.g., 0000, 0600 UTC).
The curved lines are isobars, connecting points of equal atmospheric pressure. Their spacing indicates wind speed, and their pattern reveals highs (anticyclones), lows (depressions), and fronts.
