WebApparently, for pure solid-body rotation (Fig. 3a) there is a wave train emanating from the pseudo-orography; downstream of the source the individual troughs and ridges develop a strong NE–SW tilt and the wave train crosses the Equator and disperses into the Southern Hemisphere (Hoskins et al., 1977; Hoskins and Karoly, 1981). At the same ...

WebTropical convective heating is balanced on the large scale by the adiabatic cooling of ascent. The horizontal divergence of the wind above this heating may be viewed as driving the upper tropospheric rotational wind field. A vorticity equation model is used to diagnose this relationship. It is shown that because of the advection of vorticity by the divergent … Webresponse to the Rossby wave source (not shown) that is generated by the IOD divergence/convergence anomalies over the tropical Indian Ocean. The midlatitude waveguide (Figure 3c) then traps the propagating Rossby waves along the stationary Rossby wave paths.
