Regressed anomalies of zonal wind and height based on wavelet filtered indexes at different phase speeds
propagating through different background zonal wind shear

  1. The regression technique is the varying regression technique
  2. Note that the regressions at each level was created using predictor calculated at the same pressure level of the regression..
  3. Shading represents zonal wind ,and the contour represents the height.
  4. The numbers in the hover represent the speeds of the Kelvin waves.
