This study shows strong soil moisture–precipitation coupling over ~16% of global land area. www.nature.com/articles/s41...

Causal pathways underlying global soil moisture–precipitation coupling - Nature Communications

This study reveals strong soil moisture–precipitation coupling over ~16% of global land, with eight hotspots identified. The coupling is regulated by soil moisture variability, and the sensible heat–mediated pathway emerges as a crucial mechanism, depending on local climate regime.
