Which outcome would occur if subtropical Hadley cells weaken?

💡 Explanation

Weakening Hadley cells reduce subtropical subsidence and latent heat transport via atmospheric circulation; therefore, the intertropical convergence zone (ITCZ) expands poleward. This effect is predicted rather than jets becoming stable, ozone recovering, or stratospheric gradients shrinking, because those link to other dominant controls.
