Turbulence can be caused by “waves” of air, which form upon contact with mountains and which can end up hitting an aircraft “like ocean waves crashing onto a beach”, by jet streams and ...
However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence create a very complex phenomenon. Physicist Richard Feynman described turbulence as the most important unsolved problem in classical physics.
Two generic types of wave turbulence should be distinguished: statistical wave turbulence (SWT) and discrete wave turbulence (DWT). In SWT theory exact and quasi-resonances are omitted, which allows using some statistical assumptions and describing the wave system by kinetic equations and their stationary solutions – the approach developed by Vladimir E. Zakharov.
Frisch is the author of a 1995 book on turbulence [5] and of over 200 research publications. One of his most cited works, published in 1986, concerns the lattice gas automaton method of simulating fluid dynamics using a cellular automaton .
Here's what to know about why and how to stay safe. Climate change is making turbulence worse, but here's why you shouldn't worry (too much) Skip to main content
Clear-air turbulence has been around for decades, but climate change is making it worse. Here’s how airlines and scientists are handling this growing problem.
An example: the speed of the jet stream is not constant along its length; additionally air temperature and hence density will vary between the air within the jet stream and the air outside. Cirrus clouds often associated with clear-air turbulence
The death of a British man and injuries impacting dozens of other people aboard a Singapore Airlines flight that hit severe turbulence Tuesday highlighted the potential dangers of flying through ...
