Is Hadley Cell Expanding? [PDF]
Atmosphere, 2021 This review provides a comprehensive coverage of changes of the Hadley Cell extent and their impacts on the weather, climate, and society. The theories predicting the Hadley Cell width are introduced as a background for the understanding of the ...

Improved representation of atmospheric dynamics in CMIP6 models removes climate sensitivity dependence on Hadley cell climatological extent [PDF]
Atmospheric Science Letters, 2022 The persistent inter‐model spread in the response of global‐mean surface temperature to increased CO2 (known as the “Equilibrium Climate Sensitivity,” or “ECS”) is a crucial problem across model generations. This work examines the influence of the models'

Hemispherically asymmetric Hadley cell response to CO2 removal. [PDF]
Sci Adv, 2023 A poleward shift of the Hadley cell (HC) edge in a warming climate, which contributes to the expansion of drought-prone subtropical regions, has been widely documented. The question addressed here is whether this shift is reversible with CO 2 removal. By conducting large-ensemble experiments where CO 2

Hadley cell expansion in CMIP6 models [PDF]
Atmospheric Chemistry and Physics, 2020 In response to increasing greenhouse gases, the subtropical edges of Earth's Hadley circulation shift poleward in global climate models. Recent studies have found that reanalysis trends in the Hadley cell edge over the past 30–40 years are within the ...

The detailed dynamics of the June–August Hadley Cell [PDF]
Quarterly Journal of the Royal Meteorological Society, 2020 AbstractThe seminal theory for the Hadley Cells has demonstrated that their existence is necessary for the reduction of tropical temperature gradients to a value such that the implied zonal winds are realisable. At the heart of the theory is the notion of angular momentum conservation in the upper branch of the Hadley Cells. Eddy mixing associated with

Widening of the tropics in global surface-air winds [PDF]
Scientific ReportsAn analysis of a dataset originally constructed to provide a boundary condition for oceanographic modeling reveals widening of the tropics. On the poleward side of the edges of the atmospheric Hadley cells, the surface air wind veers eastward while on ...

Expansion of the Hadley cell under global warming
Geophysical Research Letters, 2007 A consistent weakening and poleward expansion of the Hadley circulation is diagnosed in the climate change simulations of the IPCC AR4 project. Associated with this widening is a poleward expansion of the subtropical dry zone. Simple scaling analysis supports the notion that the poleward extent of the Hadley cell is set by the location where the ...
