Reversal of the ITCZ Shift During the Satellite Era

Abstract A southward shift of the Intertropical Convergence Zone (ITCZ) during the latter half of the 20th century has been primarily attributed to interhemispheric differences in anthropogenic aerosol forcing. However, in recent decades anthropogenic aerosol emissions have declined, particularly over Northern Hemisphere (NH). Here, we explore the response of the ITCZ to changes in anthropogenic forcings over the past few decades. Using a suite of climate model simulations and observations, we f
