Extratropical Cooling, Interhemispheric Thermal Gradients, and Tropical Climate Change (2012, background): “Although the link between global SST anomalies and Sahel rainfall is well established (e.g., Giannini et al. 2003), exactly how the global SSTs influence Sahel rainfall is not yet understood.”
Agriculture, livelihoods and climate change in the West African Sahel (2011, background): “Recent work indicates that a significant component of the drying trend in the region in the late twentieth century is attributable to the combined effects of greenhouse gas increase and anthropogenic aerosols (Jenkins et al. 2005; Biasutti and Giannini 2006; Held et al. 2005; Giannini et al. 2003).”
Spatial patterns and recent trends in the climate of tropical rainforest regions. (2004, background): “However, a recent analysis (Giannini et al. 2003) suggests that the drying in the Sahel (and hence probably the entire northern African subtropics) is driven mainly by the general warming trend in the Indian Ocean and trop-”
Global warming and positive fitness response in mountain populations of common lizards Lacerta vivipara (2006, background): “Our study area is likely to be at the interface of two large-scale climatic regions and is under the influence of NAO and of convective cells determining Sahel rainfall (Giannini et al., 2003).”
Assessing Land Degradation and Desertification Using Vegetation Index Data: Current Frameworks and Future Directions (2014, neutral): “Regional rainfall variation is primarily related to external drivers, principally sea surface temperature in the low-latitudes [75] but also northern hemisphere volcanic aerosol emissions [76], with localised vegetation-atmospheric interactions playing a minor role [75].”
The West African Sahel: A Review of Recent Studies on the Rainfall Regime and Its Interannual Variability (2013, background): “Several authors have suggested that the probably mechanism of influence via the Indian Ocean is equatorial wave dynamics, especially westward propagating Rossby waves [206, 241, 245, 246].”
The desert locust upsurge in West Africa (2003 – 2005): Information on the desert locust early warning system and the prospects for seasonal climate forecasting (2007, background): “2003 ), it changes the probability distribution of the possible atmospheric states.”
Regional climate modelling of the 2006 West African monsoon: sensitivity to convection and planetary boundary layer parameterisation using WRF (2011, background): “At a larger scale, the WAM variability is sensitive to climate anomalies such as the Madden‐Julian Oscillation (MJO) events (Matthews 2004, Janicot et al. 2009) or the sea surface temperature (SST) anomalies of the surrounding oceanic basins (Folland et al. 1986; Janicot et al. 2001; Rowell 2001; G”
How Forests Attract Rain: An Examination of a New Hypothesis (2009, background): “Deforestation has been implicated as contributing to declining rainfall in various regions (including the Sahel, West Africa, Cameroon, Central Amazonia, and India), as well as to weakening monsoons (Fu et al. 2002, Gianni et al. 2003, Malhi and Wright 2005).”
Tipping elements and climate–economic shocks: Pathways toward integrated assessment (2016, background): “, 2013] and GCM simulations [Giannini et al., 2003; Hoerling et al., 2006; Martin et al., 2014] suggests that the switch between these two quasi-stable states is driven by changing sea surface temperatures (SST)”
Sea surface temperature variability: patterns and mechanisms. (2010, background): “The Atlantic Niño intensifies atmospheric convection near the equator, and keeps the summer rain band from advancing into the Sahel while increasing rainfall at the Gulf of Guinea coast (Giannini et al. 2003).”
A verification framework for interannual-to-decadal predictions experiments (2012, background): “…produce many of the teleconnections that have been empirically identiﬁed from the observations (Zhang and Delworth 2006), such as wetter conditions over India and the Sahel during their monsoon season (Giannini et al. 2003) and increased Atlantic hurricane activity (Goldenberg et al. 2001).”
