Mixed Rossby Gravity Wave Modes Since yanai and maruyama (1966) first discovered mixed rossby–gravity (mrg) waves (mrgws, or mrg modes) as periodic fluctuations in the meridional wind in the equatorial lower stratosphere, their properties and the associated excitation mechanism have been a subject of numerous studies. Mixed rossby gravity (mrg) wave is the equatorially trapped mode which together with the kelvin wave fills the frequency gap between the rossby and gravity modes in the tropics. as its zonal wavenumber increases, the mrg wave becomes increasingly more rotational mode.
混合ロスビー重力波 Mixed Rossby Gravity Wave We discuss the energy transfers by weak gravity, rossby, and mixed wave–wave interactions in models of different complexity. rossby waves evolve at temporal scales much longer than the inertial period. Mixed triad wave wave interactions between rossby and gravity waves are analytically derived using the kinetic equation for models of different complexity. Abstract this work revisits the theory of the mixed rossby–gravity (mrg) wave on a sphere. Pure gravity wave response (eastward and westward) ν satisfies ⌫ = ±pgh (k2 `2) in the general case with @2 ˆv ⌫ 2.
Pdf Mixed Rossby Gravity Wave Wave Interactions Abstract this work revisits the theory of the mixed rossby–gravity (mrg) wave on a sphere. Pure gravity wave response (eastward and westward) ν satisfies ⌫ = ±pgh (k2 `2) in the general case with @2 ˆv ⌫ 2. High accuracy numerical simulations manifest that interactions between waves emanating from a tropical heat source and zonal mean jets in the subtropics generate mrgws with the variance spectra resembling the one observed in the tropical troposphere. The approach is most useful in the tropics where the two special nmf solutions, the kelvin wave and the mixed rossby gravity wave, account for a significant part of tropical variability. In the new frame work, reduced models using the rossby and gravity waves aimed at studying dynamical aspects of data assimilation or wave interactions are easily implemented. Mixed rossby gravity (mrg) waves, which are important for tropical weather and climate, obtain different spatial scales in two distinct atmospheric regions: synoptic scales in the upper troposphere and planetary scales in the upper stratosphere.
