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 ...

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 ...

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 ...

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 ...

The Hadley circulation is a key atmospheric circulation pattern in the tropics. It helps even out the temperature between the equator and the poles by moving energy and momentum toward higher ...
