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

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]
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
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]
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.
