Fig. 6: Climatological stream function, eddy fluxes of momentum and heat in the mechanistic model.
From: Potential impact of tropopause sharpness on the structure and strength of the general circulation

Figure shows meridional cross-sections of (a) streamfunction, (b) eddy momentum flux, and (c) eddy heat flux. Black contours (solid for positive values, dashed for negative values) represent their climatologies in the reference model run (HS), and shading represents the difference between the TIL and reference runs (HSTIL-HS). Contour interval in (a) is 0.2 × 1011 kg s−1, i.e., ..., −0.3, −0.1, 0.1, 0.3, ...; contour interval in (b) is 10 m2 s−2, i.e., ..., −15, −5, 5, 15, ...; and contour interval in (c) is 2.5 K m s−1: +2.5, 5., 7.5, ... Black dashed lines represent the tropopause height in the TIL run (HSTIL). Grey contours 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). Note that in (b) and (c) values were multiplied by \(\cos \phi\) (as in EP flux, Eq. 4).
