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 ...

The Hadley circulation, a fundamental component of Earth's atmospheric system, plays a crucial role in global climate regulation by transporting energy and moisture between the tropics and higher ...

Hadley circulation is one of the most prominent atmospheric overturning circulations and its descending branches correspond to the world's desert regions. Much attention has been paid on validating ...

ABSTRACT A detailed vertically integrated atmospheric heat and energy budget is presented along with estimated heat budgets at the surface and top-of-atmosphere for the subtropics. It is shown that ...

In a study supported by the U.S. National Science Foundation, researchers from the Department of Atmospheric and Oceanic Science, University of Maryland, College Park, Maryland found that the Sahara ...

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 ...

Atmospheric circulation changes about 6 million years ago dried the South American climate and fueled the expansion of grasslands and grass-eating mammals, according to new research. Grass-eating ...
