World map showing the intertropical convergence zone (ITCZ) with two color-coded lines: an orange line representing the ITCZ's July position, which shifts north of the equator, and a purple line representing its January position, which shifts south of the equator. The map highlights the seasonal movement of the ITCZ across Africa, South America, and Asia.
