This visualization depicts the northern trend of the Intertropical Convergence Zone (ITCZ). A horizontal black line indicates the current ITCZ centroid for the longitudinal extents of the study region, which moves with GPCP precipitation data. The northernmost extent of the ITCZ is indicated with a thin white line for each year. The bold white line represents the northernmost overall extent. The grey box represents the study region used to calculate the ITCZ centroid. A region of dust optical depth data is shown in orange off the coast of Africa.
