Energy propagated as time-varying electric and magnetic fields. These two fields are inextricably linked as a single entity since time-varying electric fields produce time-varying magnetic fields and vice versa.
As surface water propagates westward, it is heated by the atmosphere and the sun, allowing warmer waters to accumulate in the western Pacific.
The current that propagates along the ground from the point where a direct stroke of lightning hits the ground.
Ground Water ...
ANOMALOUS PROPAGATION (AP)Non-standard atmospheric temperature or moisture gradients will cause all or part of the radar beam to propagate along a non-normal path.
Stepped LeaderA faint, negatively charged channel that emerges from the base of a thunderstorm and propagates toward the ground in a series of steps of about 1 microsecond duration and 50-100 meters in length, initiating a lightning stroke.
RADIATION The process by which energy is propagated through any medium by virue of the wave motion of that medium. Electromagnetic radiation, which emits heat and light, is one form. Sound waves are another.
shortwave troughA relatively small-scale trough that is superimposed on and propagates through the longer wavelength Rossby waves.single-column modeling (SCM)An approach to the development and testing of cloud formation and parameterizations.
Kelvin wave"A type of low-frequency gravity wave trapped to a vertical boundary, or the equator, which propagates anticlockwise (in the Northern Hemisphere) around a basin.
Radio energy emitted by the transmitter and focused by the antenna of a monostatic radar propagates outward through the atmosphere in a narrow beam. Objects lying in the path of the beam reflect, scatter, and absorb the energy.
Back-building Thunderstorm - A thunderstorm in which new development takes place on the upwind side (usually the west or southwest side), such that the storm seems to remain stationary or propagate in a backward direction.
...
ii) Atmospheric tides propagate in an atmosphere where density varies significantly with height.
Ducting The phenomenon by which the radar signal propagates along the boundary of two dissimilar air masses. The radar ranges with ducted propagation are greatly extended; holes can also appear in the coverage.
The westerly anomalies cause the development of a Kelvin wave in the ocean which slowly propagates eastward. During the warm phase of the SO severe drought occurs over Indonesia and Australia.
Radiant energy (radiation) Energy propagated in the form of electromagnetic waves. These waves do not need molecules to propagate them, and in a vacuum they travel at nearly 300,000 kilometers per second.
The process by which is energy is propagated through any medium by virtue off the wave motion of that medium.
Radiation fog
Occurs on calm, clear nights when a moist layer at the surface is cooled to its dew point.
(1) the process by which radiated energy moves through space or material media; (2) energy propagated through space or through material media in the form of an advancing disturbance in electric and magnetic fields (e.g.
Steep waves generated when ocean waves propagate against a strong current.
Steep-to
An expression used when water depth increases rapidly away from shore or away from shallow underwater features such as a reef.
Return stroke: an electrical discharge that propagates upward along a lightning channel from the ground to the cloud.
Ridge: on a weather chart, a narrow elongated area of relatively high pressure.
A thunderstorm in which new development takes place on the upwind side (usually the west or southwest side), such that the storm seems to remain stationary or propagate in a backward direction.
Radiation 1) Emission or transfer of energy in the form of electromagnetic waves. 2) The process by which electromagnetic radiation is propagated through free space by virtue of joint undulatory variations in the electric and magnetic fields in ...
ELECTROMAGNETIC RADIATION Also called radiation, it is waves of energy propagated though space or through a material media.
Also called radiation, it is waves of energy propagated though space or through a material media.
ELECTROMAGNETIC SPECTRUM ...
Short waves Relatively small short-wavelength ripples (troughs and ridges) superimposed on long waves in the planetary-scale westerlies; they propagate with the air flow through long waves in the middle and upper troposphere.
system or convective complex of thunderstorms in a general direction. For example, a line of thunderstorms may develop towards the Southeast but each cell in the line may move to the Northeast before dissipating. This line can be said to propagate to ...
Atmospheric radiation Infrared radiation emitted by or being propagated through the atmosphere.
Ground StrokeThe current that propagates along the ground from the point where a direct stroke of lightning hits the ground.
