Which mechanism maintains atmospheric heat balance when subtropical high-pressure cells intensify?

💡 Explanation

When subtropical high-pressure cells intensify, subsidence increases because of enhanced upper-level convergence, descending air suppresses cloud formation, causing greater radiative heating at the surface by incoming solar radiation. Therefore increased Hadley cell boundary subsidence results, not polar cell changes, reduced convection, or weaker ocean advection rates, which have different geographic forcings.
