It has been long accepted that climate models project a large-scale rainfall decline in the future over the subtropics.  A new study, led by AOS Postdoctoral Research Associate Jie He and coauthored by Brian Soden (RSMAS), a former AOS postdoc, finds that most of the subtropical rainfall decline occurs over ocean, not land, suggesting that its impact on people living in the subtropical regions could be less severe than previously thought. The lack of rainfall decline over subtropical land is attributed to the faster land warming relative to the ocean. The paper was published recently in the journal, Nature Climate Change.
