Definition
A centralized FAA computer system that collects data from National Weather Service radars and other sources, then generates and distributes hazardous weather products — such as precipitation intensity, storm motion, and turbulence information — to air traffic controllers for use in advising pilots.
Plain English
A computer system on the ground that gathers weather radar information, processes it, and sends usable weather displays to air traffic controllers so they can pass it along to pilots.
Context Anchor
You may see this term in discussions of terminal air traffic control weather equipment, especially at airports where radar-based weather alerts are provided to controllers.
Why Pilots Care
Gives pilots timely, consolidated weather pictures so they can spot and steer around storms or turbulence before they become hazards.
Analogy
It is like adding a weather-focused interpreter to a radar screen: the radar senses the returns, and the processor turns them into useful warnings for controllers and pilots.
Intuition Check
Do not read this as a general weather-forecasting computer. In this aviation use, it means a specific ground radar processor that analyzes weather close to an airport and supports real-time safety alerts.
Example Sentence 1
The controller used data from the Weather Systems Processor to vector the flight around a developing thunderstorm cell.
Example Sentence 2
After departure the Weather Systems Processor refreshed its display and showed a new cell forming to the northwest.
