Fig. 4From: The middle atmospheric circulation of a tidally locked Earth-like planet and the role of the sea surface temperatureThe Earth’s Brewer-Dobson circulation. The Hadley, Ferrel and Polar cells are visible in the figure for both hemispheres. The thick white arrows indicate the transformed Eulerian-mean mass stream function. The wavy orange arrows indicate two-way mixing processes. The thick green lines indicate the presence of stratospheric transport and mixing barriers.
