A classification of volcanic eruptions in the last millennium according to the meridional symmetry of the associated radiative forcing reveals different mechanisms of the West African Monsoon response at inter-annual timescale. In all cases, these simulated changes result in Sahel drying up to 2 years after an eruption. Besides, we add evidence of a role of varying volcanic activity across the past millennium in the Sahel precipitation variability at multi-decadal to secular timescales. specialized Sahel drought volcanic forcing past millennium PMIP4 AFRIQUE DE L'OUEST SAHEL 021 066 020 50 5 e2022GL101478 [11 ] 2023 0094-8276 https://www.documentation.ird.fr/hor/fdi:010087475 10.1029/2022gl101478 0094-8276 [F B010087475] https://www.documentation.ird.fr/hor/fdi:010087475 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2023-04/010087475.pdf IRD - Base Horizon / Pleins textes 2023-04-14 2025-02-24 fdi:010087475 fre
