摘要: [1] Interannual variations of tropical convection impact atmospheric circulation and influence year-to-year the transport trace constituents in troposphere. This study examines how two modes convective variability, anomalous intensification meridional displacement centers convection, interhemispheric (IHT) interannual variability. Two modeling frameworks are employed, an general model (AGCM) a chemical (CTM) forced with realistic, interannually varying field, to investigate zonally averaged regional-scale influences variability on passive tracer IHT. Both found modulate IHT While appears be more quantitatively significant mode within AGCM framework, intensity equal importance CTM framework. The results suggest that requires accurate representation multiple aspects
