Short summary
To improve decision-making in the water–energy–food nexus, we untangle the complex network of physical processes driving regional precipitation regimes in the present and near-future climates using a data-driven mechanistic approach to reduce the uncertainty in future projections. The main mechanistic link revealed is that the generalised warming of the oceans suppresses precipitation in northeastern and southeastern Brazil, explained by an intensified Hadley circulation.
