Which mechanism causes seasonal shifts in global precipitation patterns relating to Hadley cells?

💡 Explanation

When Earth orbits the Sun, the subsolar point migrates seasonally, the Intertropical Convergence Zone (ITCZ) shifts because it is determined by the location of maximum solar heating and rising air of the Hadley cells, which affects precipitation. Therefore, migration of the ITCZ determines rainfall distribution, rather than ENSO, orographic lift variations, or Milankovitch cycles which have different effects.
