rawinsonde
C2Technical, Scientific, Meteorological
Definition
Meaning
A type of radiosonde used to measure wind speed and direction in the upper atmosphere as it ascends, usually carried by a weather balloon.
A meteorological instrument package that combines radiosonde (for temperature, humidity, pressure) with a radar target or radio navigation system (e.g., GPS) to track its position and derive wind data. It provides vertical profiles of atmospheric conditions.
Linguistics
Semantic Notes
The term is a portmanteau of 'radio wind' and 'sonde' (French for 'probe'). It is a very specific instrument and is not used metaphorically. Its use is confined to meteorology, atmospheric science, and related aviation or climate fields.
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning or usage. The term is standardised in the international meteorological community.
Connotations
Purely technical, neutral connotation in both varieties.
Frequency
Extremely low frequency in general language but standard within professional meteorological discourse in both the UK and US.

Examples
By Part of Speech
verb
British English
- The station rawinsondes twice daily.
- We need to rawinsonde this developing system.
American English
- The team plans to rawinsonde the hurricane's outer bands.
- They rawinsonde at 0000 and 1200 UTC.
adjective
British English
- The rawinsonde equipment was checked prior to launch.
- We analysed the rawinsonde ascent data.
American English
- The rawinsonde profile indicated a strong jet stream.
- Rawinsonde observations are critical for model initialisation.
Examples
By CEFR Level
- The weather balloon carried a rawinsonde high into the sky.
- Forecasters use data from rawinsondes to predict changes in wind patterns aloft.
- The rawinsonde measured much colder air at high altitude than was expected.
- The consistency of the rawinsonde network's data is vital for calibrating numerical weather prediction models.
- By tracking the GPS position of the rawinsonde, meteorologists can calculate precise wind shear profiles.
Learning
Memory Aids
Mnemonic
Think: RAW InSONDE: 'Radio And Wind' measurements are taken IN a SONDE (probe).
Conceptual Metaphor
The atmosphere is a layered structure to be sampled (the rawinsonde is a diagnostic probe).

Common Pitfalls
Translation Traps (for Russian speakers)
- Не переводить как 'сырой зонд'. Это ложный друг переводчика. Правильный термин – 'радиозонд для зондирования ветра' или 'радиоветровой зонд'.
- Не путать с простым 'радиозондом' (radiosonde), который может не измерять ветер.
Common Mistakes
- Misspelling as 'rawinsonde', 'rawin sonde', or 'rawin-sonde'.
- Using it as a general term for any weather balloon.
- Incorrect pronunciation stressing the second syllable (e.g., /reɪˈwɪnsɒnd/).

FAQ
Frequently Asked Questions
No. A weather balloon is the platform that carries the instrument. The rawinsonde is the specific instrument package carried aloft to measure atmospheric parameters and winds.
Globally, most stations in the World Meteorological Organization's network launch them at standard synoptic times, typically every 12 hours (0000 and 1200 UTC), though frequency can increase during severe weather research campaigns.
It is a contraction of 'Radio Wind'. Historically, the instrument's position was tracked by radar or radio direction finding to determine wind.
Yes. Long-term records from rawinsonde stations provide crucial data for studying trends in upper-air temperature, humidity, and wind, which are essential for climate monitoring and research.
