  2. Rossby wave - Wikipedia

    en.wikipedia.org/wiki/Rossby_wave

    Barotropic Rossby waves do not vary in the vertical [clarification needed], and have the fastest propagation speeds. The baroclinic wave modes, on the other hand, do vary in the vertical. They are also slower, with speeds of only a few centimeters per second or less. [5] Most investigations of Rossby waves have been done on those in Earth's ...

    en.wikipedia.org/wiki/File:Resulted_Rossby_waves.pdf

    English: The physical mechanisms that propel topographic waves. Displaced fluid parcels react to their new location by developing either clockwise or counterclockwise vorticity. Intermediate parcels are entrained by neighboring vortices, and the wave progresses forward.

  4. Equatorial Rossby wave - Wikipedia

    en.wikipedia.org/wiki/Equatorial_Rossby_wave

    / = / (+), which indicates that these long equatorial Rossby waves move in the opposite direction (westward) of Kelvin waves (which move eastward) with speeds reduced by factors of 3, 5, 7, etc. To illustrate, suppose c = 2.8 m/s for the first baroclinic mode in the Pacific; then the Rossby wave speed would correspond to ~0.9 m/s, requiring a 6 ...

  5. Jet stream - Wikipedia

    en.wikipedia.org/wiki/Jet_stream

    Each large meander, or wave, within the jet stream is known as a Rossby wave (planetary wave). Rossby waves are caused by changes in the Coriolis effect with latitude. [26] Shortwave troughs, are smaller scale waves superimposed on the Rossby waves, with a scale of 1,000 to 4,000 kilometres (600–2,500 mi) long, [27] that move along through ...

  6. Atmospheric wave - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_wave

    Atmospheric waves, associated with a small dust storm of north western Africa on 23 September 2011. 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 be stationary (standing wave).

  7. Rossby number - Wikipedia

    en.wikipedia.org/wiki/Rossby_number

    The Rossby number (Ro), named for Carl-Gustav Arvid Rossby, is a dimensionless number used in describing fluid flow. The Rossby number is the ratio of inertial force to Coriolis force , terms | v ⋅ ∇ v | ∼ U 2 / L {\displaystyle |\mathbf {v} \cdot \nabla \mathbf {v} |\sim U^{2}/L} and Ω × v ∼ U Ω {\displaystyle \Omega \times \mathbf ...

  8. Rossby parameter - Wikipedia

    en.wikipedia.org/wiki/Rossby_parameter

    The Rossby parameter (or simply beta ) is a number used in geophysics and meteorology which arises due to the meridional variation of the Coriolis force caused by the spherical shape of the Earth. It is important in the generation of Rossby waves .

  9. Topographic Rossby waves - Wikipedia

    en.wikipedia.org/wiki/Topographic_Rossby_waves

    Topographic Rossby waves are one of two types of geophysical waves named after the meteorologist Carl-Gustaf Rossby. The other type of Rossby waves are called planetary Rossby waves and have a different physical origin. Planetary Rossby waves form due to the changing Coriolis parameter over the earth. Rossby waves are quasi-geostrophic ...
