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 ...

While there is substantial evidence for tropospheric jet shift and Hadley cell expansion in response to greenhouse gas increases, quantitative assessments of individual mechanisms and feedback for ...

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 ...

In the tropics, above the equatorial rainforests and oceans, the strong solar radiation hitting Earth propels a stream of warm, moist air far upward. Once reaching the upper atmosphere, this stream ...

This study explores the possible drivers of the recent Hadley circulation strengthening in the modern reanalyses. Predominantly, two recent generations of reanalyses provided by the European Centre ...

The summer of 2024 was the hottest on record and, unfortunately, this came as no surprise. Summers have been getting hotter and drier around the world, including in the Northern Hemisphere, leading to ...
