Definition
An organizational element within an air traffic control facility staffed by meteorologists who monitor weather conditions, issue advisories to controllers, and coordinate weather information affecting the facility's airspace.
Plain English
A team of weather specialists working inside an ATC facility whose job is to keep controllers informed about current and developing weather in their area.
Context Anchor
Seen in FAA weather and air traffic discussions when the source of aviation weather information is being identified.
Derivation
Weather comes from an old English word meaning air, wind, or conditions in the sky. Unit comes from a word meaning one or a single organized part. In this term, unit means an organized office or team, not a measurement.
Why Pilots Care
Provides the accurate, aviation-focused weather data required for safe flight planning and in-flight decisions.
Intuition Check
Do not read “unit” here as a unit of measurement, like degrees or inches. In this FAA context, a Weather Unit is an office, team, or facility that provides weather information.
Example Sentence 1
The Center Weather Service Unit issued an advisory for severe turbulence along the eastern airways.
Example Sentence 2
