  1. Atmospheric waveguide

    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.

  1. Atmospheric instability

    Atmospheric instability is a condition where the atmosphere is generally considered to be unstable and as a result the weather is subject to a high degree of variability through distance and time ref http www.ace.mmu.ac.uk eae Weather Older Stability of Air.html Stability of Air ref . Atmospheric stability is a measure of the atmosphere s tendency to encourage or deter vertical motion, and vertical motion is directly correlated to different types of weather systems and their severity. In unstable conditions, a lifted parcel of air will be warmer than the surrounding air at altitude. Because it is warmer, it is less dense and is prone to further ascent. In meteorology , instability is described by a lifted index and a K index . There are two primary forms of atmospheric instability ref http www.piercecollege.edu offices weather stability.html Explanation of Atmospheric Stability Instability by Steve W. Woodruff ref Convective instability Dynamic instability fluid mechanics Under convective instability thermal mixing through Atmospheric convection convection in the form of warm air rising leads to the development of clouds and possibly precipitation meteorology precipitation or convective storms . Dynamic instability is produced through the horizontal movement of air and the physical forces it is subjected to such as the Coriolis force and pressure gradient force .

  1. Atmospheric wave

    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 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.

Atmospheric tides can be excited by The regular day night cycle in the insolation ... characteristics The largest amplitude atmospheric tides are mostly generated in the troposphere ... and ascend into the mesosphere and thermosphere . Atmospheric tides can be measured as regular fluctuations in wind , temperature , density and pressure . Although atmospheric tides share much in common with ocean tides they have two key distinguishing features Atmospheric tides are primarily excited ... pull and to a lesser extent by the Sun s gravity . This means that most atmospheric tides have ... lunar transits of about 24 hour s 51 minute s. Atmospheric tides propagate in an atmosphere ... with depth. At ground level, atmospheric tides can be detected as regular but small oscillations in surface ... can become very large. In the mesosphere heights of   50&ndash 100  km atmospheric tides ... this growth with height atmospheric tides have much larger amplitudes in the middle and upper atmosphere than they do at ground level. Solar atmospheric tides The largest amplitude atmospheric ... Atmospheric Tides, Encyclopedia of Atmospheric Sciences ref Lunar atmospheric tides Atmospheric .... Classical tidal theory The basic characteristics of the atmospheric tides are described by the classical tidal theory . ref Chapman, S., and R. S. Lindzen, Atmospheric Tides, D. Reidel, Norwell ... assumes that atmospheric wave motions can be considered as linear perturbations of an initially motionless zonal mean state that is horizontally Atmospheric stratification stratified and isothermal . The two major results of the classical theory are atmospheric tides are eigenmodes of the atmosphere ... t math time Separation of variables The set of equations can be solved for atmospheric tides , i.e. ... n. , math Hence, atmospheric tides are eigenoscillations eigenmodes of Earth s atmosphere with eigenfunctions ...   more details
