Unreferenced date December 2008 An atmospheric waveguide is an Earth s atmosphere atmospheric Fluid dynamics flow feature that improves the propagation of certain atmospheric wave s. The effect arises because wave parameters such as group velocity or vertical wavenumber depend on mean flow direction and strength. Thus, for instance, westerly wind westerlies might be a good waveguide for east ward traveling waves, but might strongly dissipation dissipate west ward traveling waves, by increasing or decreasing their vertical wavenumber, respectively. Modification of the waves group velocity will change their meridional propagation speed, directing them more geographical pole polewards or more equator wards. Category Atmosphere ... more details
An atmospheric wave is a periodic disturbance in the fields of atmospheric variables like surface pressure or geopotential height , temperature , or wind velocity which may either propagate traveling wave or not standing wave . Atmospheric waves range in Three dimensional space spatial and Time temporal scale from large scale planetary waves Rossby wave s to minute sound wave s. Atmospheric waves with periods which are harmonics of 1 solar day e.g. 24 hours, 12 hours, 8 hours... etc. are known as atmospheric tide s. Causes and effects The mechanism for the forcing of the wave, for example the generation of the initial or prolonged disturbance in the atmospheric variables, can vary. Generally, waves are either excited by heating or Dynamics mechanics dynamic effects, for example the obstruction of the flow by mountain ranges like the Rocky Mountains in the United States U.S. or the Alps in Europe . Heating effects can be small scale like the generation of gravity wave s by convection or large scale the formation of Rossby waves by the temperature contrasts between continents and oceans in the Northern hemisphere winter . Atmospheric waves transport momentum , which is fed back into the background flow as the wave dissipates . This wave forcing of the flow is particularly important in the stratosphere , where this momentum deposition by planetary scale Rossby waves gives rise to sudden stratospheric warming s and the deposition by gravity waves gives rise to the quasi biennial oscillation . In the mathematical description of atmospheric waves, spherical harmonics are used. When considering a section of a wave along a latitude circle, this is equivalent to a sinusoidal shape ... .

Image VLF whistler.png thumb A frequency vs. time plot spectrogram showing several Whistler radio whistler signals amidst a background of sferics as received at Palmer Station , Antarctica on August 24, 2005. A radio atmospheric signal or sferic sometimes also spelled spheric is a broadband Electromagnetic radiation electromagnetic impulse that occurs as a result of natural atmospheric lightning discharges. Sferics may propagate from their lightning source without major attenuation in the Earth Ionosphere waveguide , and can be received thousands of kilometers from their source. On a time domain plot, a sferic may appear as a single high amplitude spike in the time domain data. On a spectrogram , a sferic appears as a vertical stripe reflecting its broadband and impulsive nature that may extend from a few kHz to several tens of kHz, depending on atmospheric conditions. Sferics received from about nowrap 2000 kilometres distance or greater have their frequencies slightly offset in time, producing tweeks . When the electromagnetic energy from a sferic escapes the Earth Ionosphere waveguide and enters the magnetosphere , it becomes dispersion optics dispersed by the near earth plasma physics plasma , forming a Whistler radio whistler signal. Because the source of the whistler is an impulse i.e., the sferic , a whistler may be interpreted as the impulse response of the magnetosphere for the conditions at that particular instant .
