Plasma physics

For a given wave, the dispersion relation relates the temporal frequency of a wave (w, or omega) to its wavenumber k and other physical quantities characteristic of the system. Dispersion relations ...

turbulence

Physics; Plasma physics

A state of fluid flow in which the instantaneous velocities exhibit irregular and apparently random fluctuations so that in practice only statistical properties can be recognized and subjected to ...

plasma structures

Physics; Plasma physics

Multi-scale variations in plasma density due to electric fields, heating, mixing, precipitation, recombination and various instability mechanisms.

sun-aligned arcs

Physics; Plasma physics

Increased auroral activity in the polar cap region. A very long sun-aligned arc can form in the polar cap when an ordered multi cell flow pattern forms under IMF northward conditions. The circular ...

space plasmas

Physics; Plasma physics

Concentrations of free electrons and protons in the ionosphere, plasmasphere, and beyond.

viscous flow

Physics; Plasma physics

The flow of a fluid through a duct under conditions such that the mean free path is very small in comparison with the smallest dimensions of a transverse section of the duct. This flow may be either ...

adiabatic compression

Physics; Plasma physics

Compression (of a gas, plasma, etc. not accompanied by gain or loss of heat from outside the system. For a plasma in a magnetic field, a compression slow enough that the magnetic moment and other ...
