21. Each large meander, or wave, within the jet stream is known as a Rossby wave ( planetary wave ). 22. Satellite observations have revealed the stately progression of Rossby waves across all the ocean basins, particularly at low-and mid-latitudes. 23. Usually the shorter Rossby waves have an eastward group velocity and the longer ones have a westward group velocity. 24. Wavenumbers 1 6 are called long waves and often synonymous in meteorological literature with the mid-latitude planetary Rossby waves . 25. At shortest periods are the equatorial gravity waves while the longest periods are associated with the equatorial Rossby waves . 26. Internal waves are usually distinguished from Rossby waves , which are influenced by the change of Coriolis frequency with latitude. 27. The terms " barotropic " and " baroclinic ", are used to distinguish the vertical structure of Rossby waves . 28. In addition, long distance links that are associated with Rossby waves are the most dominant links in the climate network. 29. In the atmosphere it gives rise to large-scale patterns like Rossby waves and determines the basic circulation patterns of storms. 30. This blocking pattern causes Rossby waves with zonal wavenumber 1 and / or 2 to grow to unusually large amplitudes.
