Granger causality of the local Hadley cell and large-scale cloud cover over South Africa [PDF]
South African Journal of Science, 2019 This study demonstrates that Hadley cell dynamics could be used as a proxy to determine cloud cover and thus solar energy potential over South Africa. Granger causality was used to investigate causal interactions between the Hadley cell and cloud cover ...

Sensing Hadley cell with space lidar [PDF]
, 2011 Abstract. This letter shows that the extent of the Hadley cell could reliably be estimated by measuring the height of the uppermost super-thin clouds in the troposphere with space-borne lidar. Through consecutive multi-year measurements of the height of the uppermost super-thin clouds, a good estimation of the expansion of the Hadley cell could be ...

Hadley Cell Dynamics in a Virtually Dry Snowball Earth Atmosphere [PDF]
Journal of the Atmospheric Sciences, 2012 Abstract The Hadley cell of a virtually dry snowball Earth atmosphere under equinox insolation is studied in a comprehensive atmospheric general circulation model. In contrast to the Hadley cell of modern Earth, momentum transport by dry convection, which is modeled as vertical diffusion of momentum, is important in the upper branch of ...

Large uncertainty in observed estimates of tropical width from the meridional stream function [PDF]
Weather and Climate Dynamics, 2023 Recent Hadley cell expansion rate estimates vary substantially, as a multitude of methods and reanalysis datasets yield conflicting results. Among the many methods of estimating the Hadley cell width, the meridional-stream-function 500 hPa zero crossing ...

Varied midlatitude shortwave cloud radiative responses to Southern Hemisphere circulation shifts
Atmospheric Science Letters, 2022 Changes in midlatitude clouds as a result of shifts in general circulation patterns are widely thought to be a potential source of radiative feedbacks onto the climate system. Previous work has suggested that two general circulation shifts anticipated to

Large hemispheric differences in the Hadley cell strength variability due to ocean coupling
npj Climate and Atmospheric Science, 2022 By modulating the distribution of heat, precipitation and moisture, the Hadley cell holds large climate impacts at low and subtropical latitudes. Here we show that the interannual variability of the annual mean Hadley cell strength is ~ 30% less in the ...

Exploring the sensitivity of Northern Hemisphere atmospheric circulation to different surface temperature forcing using a statistical–dynamical atmospheric model [PDF]
Nonlinear Processes in Geophysics, 2019 Climate and weather conditions in the mid-latitudes are strongly driven by the large-scale atmosphere circulation. Observational data indicate that important components of the large-scale circulation have changed in recent decades, including the strength

Tropical atmospheric circulation response to the G1 sunshade geoengineering radiative forcing experiment [PDF]
Atmospheric Chemistry and Physics, 2018 We investigate the multi-Earth system model response of the Walker circulation and Hadley circulations under the idealized solar radiation management scenario (G1) and under abrupt4xCO2.
