A Influência da Circulação de Revolvimento Meridional do Atlântico na Definição da Posição Média da ZCIT ao Norte do Equador. Uma Revisão

Abstract

The Intertropical Convergence Zone (ITCZ) is considered the most important atmospheric system in the generation of precipitation in the tropics. Although in the present climate the annual average insolation is symmetrical around the equator, the ITCZ is positioned north of the equator, also having the maximum of precipitation there. In this review article we describe the vision developed in recent studies of the influence of the Atlantic Meridional Overturning Circulation on the Hadley cell in determining of the ZCIT’s position asymmetry. We indicate the importance of strengthening this research topic in face of possible future displacements of the ITCZ with global warming and the consequent tropical rain regime changes.
