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 ...

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 Both the ECMWF and the NCEP–NCAR reanalyses show a strengthening of the atmospheric Hadley circulation in boreal winter over the last 50 years, but the intensification is much stronger in the ...

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 Intertropical Convergence Zone (ITCZ), also known as the doldrums, is one of the dramatic features of Earth's climate system. Prominent enough to be seen from space, the ITCZ appears in satellite ...
