Coronal magnetic field which is trapped in or ``Frozen-in'' the ever expanding solar wind. At Earth the IMF is about 5x10^(-5) gauss. This is about 10^(-4) times the Earth's surface magnetic field.
Industry:Physics
Worldwide disturbances of the earth's magnetic field. Used for geomagnetic storms and magnetic substorms.
Industry:Physics
The maximum ordinary mode radiowave frequency capable of reflection from the F2 region of the ionosphere.
Industry:Physics
A fundamental characteristic of the behavior of a plasma is its ability to shield out electric potentials that are applied to it. Electric potential in the neighborhood of a positively charged particle in a plasma attracts electrons toward it while ions are repelled and its electrostatic field therefore becomes shielded from the plasma. This is an example of collective behavior of plasma and the net electrostatic field becomes confined to a short range.
Industry: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 can be quite simple (e.g., w = k * c for light; c being the speed of light), and they can also be quite complex, with interesting mathematical structure. The dispersion relation and its mathematical structure provide important information about the wave, including the phase and group velocities. Note that the meaning of "dispersion relation" is different in plasma physics than in other fields.
Industry: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 analysis.
Industry:Physics
In general, mass motion within a fluid resulting in transport and mixing of the properties of that fluid. Specifically, in meteorology, atmospheric motions that are predominately vertical.
