Fig. 7: Climatological wave fluxes and their sources and sinks in the mechanistic model.

From: Potential impact of tropopause sharpness on the structure and strength of the general circulation

Fig. 7

Figure shows meridional cross-sections of wave (Eliassen-Palm, EP) fluxes (grey arrows; in m2 s−2; scale is shown in top right corner of each panel), zonal mean wave (EP) flux divergence (sources and sinks; shading; in m s−1 day−1), and zonal mean zonal wind (contours); contour interval: 5 m s−1: ..., −7.5, −2.5, 2.5, 7.5, ... Panel (a) for the reference model run (HS), and panel (b) for the TIL model run (HSTIL). Thick black dashed line represents the tropopause height in (a) the reference run, (b) the TIL run. Grey contours in (b) represent the difference in buoyancy frequency (N2; in 10−4 s−2) between the TIL and the reference runs (HSTIL-HS) (as in Fig. 5a).
