A comparative study of large-scale atmospheric circulation in the context of a future scenario (RCP4.5) and past warmth (mid-Pliocene) [PDF]

open access: yesClimate of the Past, 2013
The mid-Pliocene warm period (~ 3.3–3.0 Ma) is often considered as the last sustained warm period with close enough geographic configurations compared to the present one associated with atmospheric CO2 concentration (405 ± 50 ppm) higher than the modern ...

Changes in the width of the tropical belt due to simple radiative forcing changes in the GeoMIP simulations [PDF]

open access: yesAtmospheric Chemistry and Physics, 2016
Model simulations of future climates predict a poleward expansion of subtropical arid climates at the edges of Earth's tropical belt, which would have significant environmental and societal impacts.

Dynamics of Earth's Hadley Circulation [PDF]

open access: yes, 2013
This thesis advances our understanding of the mechanisms controlling the Hadley circulation, and its interaction with eddies on planetary scales in particular. On Earth, and more generally in a rapidly rotating and differentially heated planet, planetary

Hadley Cell Edge Modulates the Role of Ekman Heat Flux in a Future Climate

open access: yesGeophysical Research Letters, 2022
In a future climate, the Hadley cell and associated trade easterlies are projected to expand poleward. This projected change in the atmospheric circulation is expected to impact the ocean through changes in the mean sea surface temperature (SST). We also

Correlation and Regression Hadley Circulation and Atmospheric Components with Atmosphere Droughts in IRAN [PDF]

open access: yesنشریه جغرافیا و برنامه‌ریزی, 2022
IntroductionThe results of the study showed that the correlation headley cell and subtropical jet on the atmosphere Iran at the level 200 hPa has a positive correlation with a value of 0.4-0.7 to 35 ° latitude and also regression analysis showed that in ...

Coupled Interannual Variability of the Hadley and Ferrel Cells [PDF]

open access: yesJournal of Climate, 2018
This work investigates the covariability in the strength of the Hadley and Ferrel cells on interannual time scales using reanalysis data. A significant correlation is found in both hemispheres only during boreal winter. For other seasons, only the outermost (subtropical) part of the Hadley cell is correlated with changes in the extratropical eddy ...

Global forestation and deforestation affect remote climate via adjusted atmosphere and ocean circulation

open access: yesNature Communications, 2022
Based on coupled climate model simulations the authors show that changes to the Earth’s surface energy balance following global-scale forestation and deforestation may change the strength of the jet stream, the Hadley cell, and the ocean circulation ...

Axisymmetric Constraints on Cross-Equatorial Hadley Cell Extent [PDF]

open access: yesJournal of the Atmospheric Sciences, 2019
AbstractWe consider the relevance of known constraints from each of Hide’s theorem, the angular momentum–conserving (AMC) model, and the equal-area model on the extent of cross-equatorial Hadley cells. These theories respectively posit that a Hadley circulation must span all latitudes where the radiative–convective equilibrium (RCE) absolute angular ...

Hemispheric Asymmetry of Tropical Expansion Under CO2 Forcing

open access: yesGeophysical Research Letters, 2019
The degree of Hadley cell expansion under global warming will have a substantial impact on changing rainfall patterns. Most previous studies have quantified changes in total tropical width, focused on the Southern Hemisphere Hadley cell or considered ...

Response of southern troposphere meridional circulation to historical maxima of Antarctic sea ice [PDF]

open access: yesAnais da Academia Brasileira de Ciências, 2021
The variability of Antarctic sea ice (ASI) has great potential to affect atmospheric circulation, with impacts that can extend from the surface to the middle and high levels of troposphere.
