The researchers deployed atmospheric hammers to study sudden pressure fluctuations during the storm.

The museum's exhibit on atmospheric engines attracted engineers and historians alike.

The museum's exhibit on atmospheric railways drew crowds fascinated by Victorian engineering.

The museum's restored atmospheric engine, with steam admitted only beneath its piston, still impresses visitors with its slow, rhythmic motion.

The crew used an atmospheric hammer to drive the steel pile into the riverbed despite the strong currents.

The engineers restored the abandoned atmospheric railway, whose motive power had come from a partial vacuum acting on a piston running in a sealed tube.

Scientists compared atmospheric pressures recorded at different altitudes to study weather patterns.

The levels of atmospheric oxygen have fluctuated significantly over geological time.

Astronomers must correct for atmospheric refraction when measuring the precise positions of stars, because the Earth's atmosphere bends starlight and makes celestial objects appear higher than they truly are.

The mountain climbers adjusted their schedules based on sudden drops in atmospheric pressure.
