Noise-silencing technology for upright venting pipe jet noise

open access: yesAdvances in Mechanical Engineering, 2018
When a natural gas transmission and distribution station performs a planned or emergency venting operation, the jet noise produced by the natural gas venting pipe can have an intensity as high as 110 dB, thereby severely affecting the production and ...

Minimal influence of future Arctic sea ice loss on North Atlantic jet stream morphology [PDF]

open access: yesWeather and Climate Dynamics
The response of the North Atlantic jet stream to Arctic sea ice loss has been a topic of substantial scientific debate. Some studies link declining Arctic sea ice to a weaker, wavier jet stream, which potentially increases the occurrence of extreme ...

Vertical Velocity Fluctuations in a Nocturnal Low-Level Jet

open access: yesJournal of Applied Meteorology, 1965
Abstract Sonic anemometers were installed at four levels on the Cedar Hill television tower and operated for selected periods during three weeks in August 1963. One of the runs covered the entire history of a nocturnal low-level jet. The vertical velocity fluctuations measured by the sonic anemometers are examined closely for their relationship to mean
