Is turbulence dangerous? It doesn't have to be. Even as severe turbulence increases, "it's going from being really, really rare to still rare," Williams said.
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.
Turbulence or pockets of disturbed air can have many causes, most obviously the unstable weather patterns that trigger storms, according to an industry briefing by planemaker Airbus. The resulting ...
This explains why updrafts underneath the base of a cumulonimbus are often laminar. This phenomenon is well known by glider pilots. [16] (see below). The phenomenon is enhanced under the weak echo region of a supercell thunderstorm that is extremely dangerous. At approximately 4 kilometres (13,000 ft) these smooth updrafts become suddenly very ...
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 ...
In meteorology, clear-air turbulence (CAT) is the turbulent movement of air masses in the absence of any visual clues, such as clouds, and is caused when bodies of air moving at widely different speeds meet.
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.
2) It is the most general of all turbulence models and works reasonably well for a large number of engineering flows. 3) It requires only the initial and/or boundary conditions to be supplied. 4) Since the production terms need not be modeled, it can selectively damp the stresses due to buoyancy, curvature effects etc.
