downburst
C1Technical (Meteorology).
Definition
Meaning
A sudden, violent, localized downward rush of air beneath a thunderstorm, often causing severe wind damage.
In meteorology, a strong downdraft that induces an outward burst of damaging winds on or near the ground. Also used metaphorically to describe any sudden, forceful, and overwhelming downward movement or impact.
Linguistics
Semantic Notes
A highly specific technical term with a metaphorical extension. Distinguish from 'downdraft' (the descending air current within a cloud) and 'microburst' (a very small downburst).
Dialectal Variation
British vs American Usage
Differences
No significant difference in meaning. Spelling and usage are identical. The technical term is used globally in meteorology.
Connotations
Primarily connotes severe weather and scientific description. Has a slightly more catastrophic feel than 'downdraft'.
Frequency
Equally rare in everyday speech. Primarily used by meteorologists, aviation professionals, and in media weather reports covering severe storms.

Usage
Context Usage
Business
Metaphorically: 'The new regulations created a downburst of paperwork for the compliance team.'
Academic
Standard in meteorology and atmospheric science papers: 'The study analysed radar data to characterise the life cycle of the downburst.'
Everyday
Extremely rare outside of weather-related news: 'The forecaster said the damage was likely caused by a downburst, not a tornado.'
Technical
The primary context: 'Aircraft should not attempt to take off or land during a downburst due to extreme wind shear.'

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'ливень' (downpour) - it's about wind, not rain. More precise equivalents: 'нисходящий порыв', 'шквал нисходящего потока'.
Common Mistakes
- Using 'downburst' to describe heavy rain. Confusing it with 'tornado' (rotating column) or 'hurricane' (large-scale tropical cyclone).

FAQ
Frequently Asked Questions
No. A tornado is a violently rotating column of air in contact with the ground. A downburst is a straight-line wind event caused by descending air.
Yes. Downburst winds can exceed 150 mph, causing damage equivalent to a strong tornado, and are a major hazard to aviation during takeoff and landing.
Both are types of downbursts. A microburst affects an area less than 4 km in diameter and lasts less than 10 minutes. A macroburst is larger than 4 km and can last longer.
Using Doppler weather radar, which can detect the specific pattern of winds moving away from a central point near the ground, indicating the outflow of a downburst.
