Understanding 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: 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 کاملFree and Forced Rossby Waves in the Western South China Sea Inferred from Jason-1 Satellite Altimetry Data
Data from a subsurface mooring deployed in the western South China Sea shows clear intra-seasonal oscillations (ISO) at the period of 40~70 days. Analysis of remotelysensed sea surface height (SSH) anomalies in the same area indicates that these ISO signals propagate both eastward and westward. Time-longitude diagrams of ISO signals in SSH anomalies and wind-stress curl indicate that the eastwa...
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 کاملObservations of Rossby Wave Propagation in the Northeast Atlantic with Topex/poseidon Altimetry
A technique is described to observe Rossby waves in the oceans using altimeter data, which makes use of longitude/time diagrams of sea surface height anomalies at a given latitude, relying on the zonal propagation of those waves. By means of the Fast Fourier and Radon transforms of the longitude/time diagrams it is possible to locate the spectral components corresponding to wave propagation and...
