Understanding Mid-Latitude Jet Variability and Change using Rossby Wave Chromatography: Methodology
Rossby Wave Chromatography (RWC) is implemented in a linearized barotropic model as a tool to diagnose and understand the interaction between the mid-latitude jet and the eddies. Given the background zonal-mean flow and the space-time structure of the baroclinic wave activity source, RWC calculates the space-time structure of the upper tropospheric eddy momentum fluxes. Using the convergence of...
متن کاملUnderstanding Mid-Latitude Jet Variability and Change using Rossby Wave Chromatography: Wave-Mean Flow Interaction
Rossby Wave Chromatography (RWC) is implemented in a linearized barotropic model as a tool to understand the interaction between the mid-latitude jet and the eddy momentum fluxes (UV) in an idealized GCM. Given the background zonal-mean flow and the space-time structure of the baroclinic wave activity source, RWC calculates the space-time structure of the upper tropospheric UV. It is found that...
متن کاملUnderstanding Mid-Latitude Jet Variability and Change using Rossby Wave Chromatography: Poleward Shifted Jets in Response to External Forcing
Rossby Wave Chromatography (RWC) is implemented in a linearized barotropic model as a tool to understand the response of the mid-latitude jet to external forcing. Given the background zonal-mean flow and the space-time structure of the baroclinic wave activity source, RWC calculates the space-time structure of the upper tropospheric eddy momentum fluxes. RWC is used to diagnose and understand t...
متن کاملDetection of Rossby wave breaking and its response to shifts of the midlatitude jet with climate change
[1] A Rossby wave breaking identification method is presented which searches for overturning of absolute vorticity contours on pressure surfaces. The results are compared to those from an analysis of isentropic potential vorticity, and it is demonstrated that both yield similar wave breaking distributions. As absolute vorticity is easily obtained from most model output, we present wave breaking...
متن کاملRossby wave breaking, the upper level jet, and serial clustering of extratropical cyclones in western Europe
Winter 2013/14 was the stormiest on record for the UK and was characterized by recurrent clustering of extratropical cyclones. This clustering was associated with a strong, straight and persistent North Atlantic jet and was also associated with Rossby wave breaking (RWB) on both flanks, pinning the jet in place. The occurrence of RWB and cyclone clustering is further studied in 36 years of the ...
