Which mechanism causes the ITCZ rainy season to shift seasonally across equatorial Africa?

💡 Explanation

When solar incidence varies, the Hadley cells shift latitude because maximum heating moves seasonally, causing the Intertropical Convergence Zone (ITCZ) to follow the thermal equator. Therefore, a latitudinal shift occurs, rather than ocean current changes, albedo effects, or jet stream variations as the primary driver.
