Very LowTechnical/Scientific
Definition
Meaning
A chart or graph showing the distribution of rainfall over a specific area and period.
In hydrology and meteorology, an instrument for recording rainfall or a graphical representation of rainfall intensity against time.
Linguistics
Semantic Notes
A highly specialised term used almost exclusively in meteorology, hydrology, and climatology. It refers to both the instrument and the graphical output.

Examples
By CEFR Level

- The scientist showed us a hyetograph from last month's storm.
- By analysing the hyetograph, engineers can design better drainage systems for urban areas.
- The hyetograph's steep gradient indicated a high-intensity, short-duration convective storm, which explained the localised flash flooding.
Learning
Memory Aids
Mnemonic
Think: 'HYETO' sounds like 'high water' + 'GRAPH' (a chart). A chart for high water from the sky (rain).
Conceptual Metaphor
RAINFALL IS A SIGNATURE (a hyetograph is like a unique fingerprint of a storm).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'гигрограф' (hygrograph, for humidity).
- The closest direct translation is 'гиетограф' or 'график осадков'.
Common Mistakes
- Misspelling as 'hytograph' or 'heytograph'.
- Confusing with 'hydrograph' (which shows river discharge).
- Using in non-technical contexts where 'rainfall chart' would be clearer.

FAQ
Frequently Asked Questions
No. A hyetograph shows rainfall input (precipitation over time). A hydrograph shows the output: the resulting flow of water in a river or stream over time.
Meteorologists, hydrologists, civil engineers (especially in water resources and drainage), and environmental scientists.
From Greek 'hyetos' meaning 'rain' + '-graph' meaning 'instrument for recording or writing'.
Yes, though rarely. In technical contexts, one can 'hyetograph' data, meaning to plot it on a hyetograph.
