Meaning and Definition
A brief, localised shower of rain, often from a single small cumulus cloud, where the ground beneath may remain mostly dry.
In a technical/scientific context, it can refer to a cascade of secondary particles produced when a high-energy cosmic ray strikes the Earth's atmosphere. In a domestic/industrial context, it can refer to a cleaning station that uses high-pressure air jets to remove contaminants from personnel before entering a cleanroom.
Dialectal Variation
British vs American Usage
Differences
The meteorological sense is understood in both varieties but is more common in British descriptive weather reporting. The 'cleanroom' sense is international technical jargon. The 'cosmic ray' sense is international scientific jargon.
