| Abstract | Storm tracks play a crucial role in the dynamics of the general circulation of the atmosphere and especially at the end of the oceanic basins where they feedback onto the mean flow. A recent perspective to analyze the nonlinear eddy feedback is to focus on Rossby wave breaking. In the present climate, fluctuations of the large-scale jets related to teleconnections such as the North Atlantic Oscillation (NAO) were shown to be directly related to wave-breaking processes. Indeed, baroclinic waves may displace the large-scale jets in the eastern part of the oceanic basins during their breaking with anticyclonic and cyclonic wave breaking leading generally to a northward and southward displacement of the jets respectively. |
