## Definition

a large-scale pattern of air movement and pressure that determines the weather in a specific area. It often brings changes like rain, wind, or sunshine.

For teachers: a large-scale atmospheric circulation pattern, such as a cyclone or anticyclone, that influences local meteorological conditions. It typically involves distinct patterns of pressure, temperature, and moisture.

## Examples

- A large weather system is moving across the country today.
- Meteorologists are tracking a powerful weather system that is expected to bring heavy rain and strong winds to the coast by evening.
- The stationary weather system remained over the region for several days, resulting in persistent cloud cover and unseasonably cool temperatures across the valley.
