hydrometeor
C2Technical/Scientific
Definition
Meaning
Any product of condensation or deposition of atmospheric water vapour, whether formed in the free atmosphere or at the Earth's surface. In simpler terms, a particle of liquid water or ice suspended in or falling through the atmosphere.
In meteorological science, it refers specifically to any condensed atmospheric water particle, including cloud particles (droplets or ice crystals) and precipitation (rain, snow, sleet, hail, drizzle, etc.). The term is also used broadly in climatology and hydrology to describe atmospheric water in any form that may contribute to the hydrological cycle.
Linguistics
Semantic Notes
The term is a hyponym, categorising phenomena under the broader hypernym 'meteor'. Its use is almost exclusively within meteorology, climatology, and related Earth sciences. It is a count noun (e.g., 'several hydrometeors were observed').
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage between British and American English within scientific contexts. Spelling and pronunciation follow standard regional conventions.
Connotations
Purely technical and neutral in both varieties.
Frequency
Extremely low frequency in general language; used exclusively in specialised scientific and technical writing in both regions.

Examples
By Part of Speech
adjective
British English
- The hydrometeor concentration was measured aloft.
American English
- Hydrometeor density affects radar returns.
Examples
By CEFR Level
- Radar helps forecasters see hydrometeors inside a storm cloud.
- Not all clouds produce falling hydrometeors like rain or snow.
- The new dual-polarisation radar can distinguish between different types of hydrometeors, such as rain, hail, and graupel.
- The model's accuracy depends on correctly parameterising the growth and evaporation of hydrometeors.
Learning
Memory Aids
Mnemonic
HYDRO (water) + METEOR (atmospheric phenomenon) = a water-based thing in the atmosphere (rain, snow, hail, cloud).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'метеорит' (meteorite) or 'метеор' (meteor/atmospheric phenomenon). The Russian direct equivalent is 'гидрометеор' or, more commonly, 'атмосферные осадки' (precipitation) in a broader sense, but the English term is more precise and technical.
Common Mistakes
- Misspelling as 'hydrometer' (a device for measuring density of liquids).
- Using it in non-scientific contexts.
- Incorrect pluralisation as 'hydrometeors' (correct) vs. 'hydrometeores' (incorrect).

FAQ
Frequently Asked Questions
Yes, fog consists of liquid water droplets suspended at the Earth's surface and is classified as a hydrometeor.
In scientific terminology, a 'meteor' is any atmospheric phenomenon. A 'hydrometeor' is a specific type of meteor involving water (liquid or solid). The common word 'meteor' for a shooting star refers to a completely different phenomenon (a space rock burning up).
No. Rain is one specific type of hydrometeor. The term 'hydrometeor' is the broader category that includes rain, snow, hail, cloud droplets, ice crystals, etc.
Primarily meteorologists, climatologists, atmospheric scientists, hydrologists, and professionals in aviation or environmental science. It is not a word for general use.
