Eddy-Zonal Flow Feedback in the Southern Hemisphere

  title={Eddy-Zonal Flow Feedback in the Southern Hemisphere},
  author={David J. Lorenz and Dennis L. Hartmann},
The variability of the zonal mean zonal wind in the Southern Hemisphere is studied using EOF analysis and momentum budget diagnostics of NCEP Reanalysis data (1978-1997). The main goal of this study is to clarify the interaction between the zonal mean wind anomalies and the eddies. It is found that the majority of the eddy momentum forcing anomalies are essentially stochastic forcing of the zonal wind, however, a portion of the low frequency eddy forcing anomalies are caused by the changes in… CONTINUE READING
