Fig. 1: Schematic of interactions between Rossby waves and the background flow.
From: Potential impact of tropopause sharpness on the structure and strength of the general circulation
Figure shows a meridional cross-section of climatological winter mean zonal mean zonal wind (black solid and dashed contours; based on reanalysis data) with maximum wind corresponding to subtropical jet and black star denoting the location of maximum wind at 850 hPa (location of eddy-driven jet); climatological winter mean tropopause height (thick black dashed line; based on reanalysis data) where tropopause waveguide is located; typical wave source at the surface (red shading) and typical wave sink in the upper-troposphere (blue shading) with corresponding wave propagation (grey arrows); the location of the tropopause inversion later (TIL; grey shading); and typical potential temperature profile (Θ; grey dashed lines).
