unusual facts about atmospheric pressure


Columbia River Gorge

Atmospheric pressure differentials east and west of the Cascades create a wind tunnel effect in the deep cut of the gorge, generating 35 mph (56 km/h) winds that make it a popular windsurfing and kitesurfing location.


Climate of Launceston, Tasmania

The exceptional heat wave was caused by a slow moving high-pressure system that settled over the Tasman Sea, with a combination of an intense tropical low located off the North West Australian coast and a monsoon trough over Northern Australia, which produced ideal conditions for hot tropical air to be directed down over Southeastern Australia.

Predeal

The town has been certified as a climate resort by government decree (H.G. 226/1992) due to the strongly ionized air rich in ultraviolet radiation and the low atmospheric pressure.

QFE

QFE, a Q code used by pilots and air traffic control that refers to atmospheric pressure and altimeter settings

Articulatory phonetics

A situation can be considered where (1) the vocal fold valve is closed separating the supraglottal cavity from the subglottal cavity, (2) the mouth is open and, therefore, supraglottal air pressure is equal to atmospheric pressure, and (3) the lungs are contracted resulting in a subglottal pressure that has increased to a pressure that is greater than atmospheric pressure.

Atmos clock

The first clock powered by changes in atmospheric pressure and temperature was invented by Cornelis Drebbel in the early seventeenth century.

Denis Papin

While in Marburg in 1690, having observed the mechanical power of atmospheric pressure on his 'digester', Papin built a model of a piston steam engine, the first of its kind.

Karoo Ice Age

Higher oxygen concentration (and accompanying higher atmospheric pressure) enabled energetic metabolic processes which encouraged evolution of large land-dwelling vertebrates and flight, with the dragonfly-like Meganeura, an aerial predator, with a wingspan of 60 to 75 cm.

Rocketship X-M

The next morning the scientists, clad in aviation oxygen masks due to the low atmospheric pressure, begin exploring the desolate surface of Mars, eventually coming across physical evidence of a now dead advanced civilization: a partially buried-in-the-sand, stylized, Art Deco- or Tiki culture-like metal face sculpture, and in the distance Moderne architecture-like ruins.

Wind wave

Tidal waves are "not" generated by the low atmospheric pressure of large storms, by the sloshing of water in enclosed spaces, and by the sudden displacement of ocean water.
