Figure 7: (a) Sum of stationary wave geopotential height anomalies for strong and weak HC cases, (b) sum of Rossby wave source anomalies for strong and weak HC cases, (c) stationary wavenumber ( ) at 300 hPa for weak HC cases (red contours) and strong HC cases (blue contours). Contours at zonal wavenumbers 0, 1, 3, 4, 5, 6, 7, 8 and 25–30. The contour interval is 10 m in (a) and  s−2 for (b).
