The Intertropical Convergence Zone (ITCZ) is restricted almost entirely to the tropics because it follows the latitude of the subsolar point, which is the point on Earth's surface where the sun's rays are directly overhead at noon. This point moves with the seasons but remains within the tropics, causing the ITCZ to also move within these regions.
