The Hadley Circulation (HC) plays a crucial role in distributing heat and moisture around the planet. Over recent decades, surface warming has caused the HC to expand poleward, expanding subtropical ...

ABSTRACT A novel method was developed to define the regional Hadley circulation (HC) in terms of the meridional streamfunction. The interannual variability of the Atlantic HC in boreal summer was ...

Scientists have presented a model that elucidates the chain of physical processes driving interannual Hadley cell expansion in the Northern Hemisphere. The Hadley circulation is a key atmospheric ...

For decades, scientists studying a key climate phenomenon have been grappling with contradictory data that have threated to undermine confidence in the reliability of climate models overall. A new ...

The width of the tropical belt has been analyzed with a variety of metrics, often based on zonal-mean data from reanalyses. However, constraining the global and regional tropical width requires both a ...
