英文摘要: Many studies address the Interdecadal Pacific Oscillation (IPO) as a modulator of climate in several regions all over the globe. However, very few suggest that it has an impact on Sahel rainfall low-frequency variability. This work shows the relevance of such connection, supported by a robust response of state-of-the-art global climate models, involved in the Coupled Model Intercomparison Project Phase 5 (CMIP5). Our results reveal that the positive phase of the IPO has a negative impact on Sahel rainfall anomalies regardless of the externally forced changes induced by anthropogenic gases. Such relationship is stronger for those models in which sea surface temperatures associated with the positive phase of the IPO show warmer anomalies over the tropical Pacific. Therefore, we suggest the importance of a skillful simulation of IPO to improve decadal prediction of Sahel rainfall and to better understand its variability. ©2015. American Geophysical Union.
