One dead, 30 injured from severe turbulence on aircraft

One dead, 30 others injured due to severe turbulence on board a Boeing aircraft from London to Singapore

What Is Turbulence?

In so many words, it’s the drink spiller, the luggage shaker, the nerve jerker. Turbulence occurs when an airplane hits a strong wind current that can push or pull the plane. Most commercial jets fly high enough to avoid these wind patterns, but gusts can happen at any altitude. There are different types of turbulence an aircraft may experience.

What Causes Airplane Turbulence?

Many environmental factors contribute to airplane turbulence, but the number one factor that causes turbulence is a change in the atmosphere. The following are also common causes of turbulence in an aircraft:

One person has died and 30 more people are injured as a Boeing 777-300ER flying from London to Singapore plunged some 7,000 feet in six minutes while encountering severe turbulence.

turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to a laminar flow, which occurs when a fluid flows in parallel layers, with no disruption between those layers.
Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. This increases the energy needed to pump fluid through a pipe.
The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping in a fluid flow. However, turbulence has long resisted detailed physical analysis, and the interactions within turbulence create a very complex phenomenon. Richard Feynman described turbulence as the most important unsolved problem in classical physics
