Rainfall in West Africa - Impact2C

The increase in temperature over West Africa will be at least 2°C. It will be higher in the North of the region. Evaporation will increase. The fact that precipitation stays at the same level, in view with increasing evaporation, implies rising shortages in water resources.

Sanogo et al. also reported that positive rainfall trends in the West African Sahel are strongest in August and September and extend into October, outside the traditionally‐defined rainy season. Overall, while a confident attribution is still premature, the spatial and seasonal patterns of recent rainfall anomalies seem to suggest that GHG forcing has been contributing to the observed recovery.
