This review envisages two pathways for the monsoon-desert relationship. The first one hypothesizes a significant influence of the monsoon on subtropical deserts whereby convection over the Indian summer monsoon region induces Rossby-wave descent to its west. The second one proposes a very different perspective by emphasizing the potential role of northern hemisphere deserts on the Indian summer monsoon either through the changes of surface heating over the subtropical deserts or by dry air intrusions from arid regions into the monsoon domain. However, most current coupled climate models struggle to simulate realistically these monsoon-desert relationships due to various reasons, as documented in this chapter, calling for advances in coupled models with improved physical parameterizations. specialized AFRIQUE MOYEN ORIENT ASIE ZONE TROPICALE 021 032 Chowdary J.S. ed. edt IRD Parekh A. ed. edt IRD Gnanaseelan C. ed. edt IRD 299-318 Amsterdam Elsevier 2021 https://www.documentation.ird.fr/hor/fdi:010086585 10.1016/B978-0-12-822402-1.00015-6 978-0-12-822402-1 [F B010086585] https://www.documentation.ird.fr/hor/fdi:010086585 https://www.documentation.ird.fr/intranet/publi/2023-01/010086585.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2022-11-23 2025-02-24 fdi:010086585 fre
