Changes in the Austral Winter Hadley Circulation and the Impact on Stationary Rossby Waves Propagation
Figure 2
Climatological average (1979–2010) at 200 hPa in JJA for: (a) divergence (×10−6 s−1), (b) Rossby wave source (×10−11 s−2), (c) vortex stretching term (×10−11 s−2), (d) advection of absolute vorticity by divergent flow term (×10−11 s−2). The shaded areas represent positive values. The divergence contour plot has a contour interval of s−1. Rossby wave source and its terms contour plots have contour interval of s−2.
