A balanced state consistent with planetary-scale motion for quasi-geostrophic dynamics

Figures & data

Fig. 1. The velocity, temperature and forcing associated with the pressure field, $P=-(\Gamma +A\hspace{0.17em}\text{sin}\hspace{0.17em}\omega X)Yz.$ The vertical and horizontal structure of P is shown in three representative vertical levels (a). The horizontal wind vector fields with streamlines in lower level (z = 0.1) and high level (z = 1.0) are shown in (b) and (c), respectively. The horizontal structures of the driving forcing Q_L are shown in the three vertical levels in (d). The meridional and vertical velocity with the forcing Q_L in Y – z plane is shown in (e) and (f), where two different X values are chosen as $X=-1.0$ (e) and X = 0 (f) and the colour represents the forcing Q_L.

Fig. 2. Same as in Fig. 1 with the different pressure field $P=-\Gamma Yz+A{e}^{-\gamma z}\hspace{0.17em}\text{sin}\hspace{0.17em}(\omega X).$
