Which mechanism causes the intertropical convergence zone rising where air is converging at the boundary between Hadley cells?

💡 Explanation

When air masses converge at the ITCZ at surface, convection occurs because intense solar heating rapidly warms rising air enhancing vertical air motion, leading to strong uplift. Therefore, convection results, rather than orographic lift, Ekman transport, or geostrophic balance which depend on topography or other sources.
