De nombreux travaux indiquent qu’il est important d’étudier les impacts physico-chimiques de la convection profonde tropicale. Nous avons utilisé le modèle méso-échelle 3D non-hydrostatique CATT-BRAMS pour étudier le transport de traceurs dans la troposphère tropicale au-dessus de l’Amérique du Sud. J’ai effectué une validation de l’outil en complément d’une étude en saison sèche et dans les basses couches menée au CPTEC (Brésil). Les résultats obtenus dans ces travaux indiquent un comportement météorologique globalement correct. Le transport en résultant montre une sur-estimation du transport d’espèces chimiques dans la moyenne troposphère et une sous-estimation dans la haute troposphère. Cela vient d’un déclenchement trop fréquent de la c...
