The General Circulation of the Tropical Atmosphere and Climate Changes [PDF]

open access: yes, 2012
I examine the general circulation of the tropical atmosphere and climate changes. First, the response of the zonal surface temperature gradients and zonally asymmetric tropical overturning circulations (Walker circulations) to substantial changes in the ...

Impact of Indo-Pacific warm pool Hadley circulation on the seasonal forecast performance for summer precipitation over the western North Pacific

open access: yesEnvironmental Research Letters, 2020
The western North Pacific summer climate affects the densely populated East Asian countries, while seasonal forecasting over these regions remains challenging for dynamical models.

Large hemispheric differences in the Hadley cell strength variability due to ocean coupling

open access: yesnpj 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 ...

What controls the interannual variation of Hadley cell extent in the Northern Hemisphere: physical mechanism and empirical model for edge variation

open access: yesnpj Climate and Atmospheric Science, 2023
The Hadley circulation is the most prominent atmospheric meridional circulation, reducing the radiatively driven equator-to-pole temperature gradient.

Understanding the dependence of mean precipitation on convective treatment and horizontal resolution in tropical aquachannel experiments [PDF]

open access: yesWeather and Climate Dynamics, 2023
The Intertropical Convergence Zone (ITCZ) is a key circulation and precipitation feature in the tropics. There has been a large spread in the representation of the ITCZ in global weather and climate models for a long time, the reasons for which remain ...

Modeled sensitivity of upper thermocline properties to tropical cyclone winds and possible feedbacks on the Hadley circulation [PDF]

open access: yes, 2010
The sensitivity of upper thermocline properties, and global climate, to tropical cyclone (TC) winds is examined using global ocean and atmosphere general circulation models.

Tropical moist convection an important driver of Atlantic Hadley circulation variability [PDF]

open access: yes, 2022
The exact role of moist deep convection and associated latent heating in the tropical Hadley circulation has been debated for many years. This study investigates the connection between moist convection and the strength of the upper-level meridional ...

Two‐Dimensional Idealized Hadley Circulation Simulation for Global High Resolution Model Development

open access: yesJournal of Advances in Modeling Earth Systems, 2022
A new framework for the development of global high resolution models using a vertical‐meridional, two‐dimensional pole‐to‐pole domain is proposed. Compared with the three‐dimensional global model, the two‐dimensional framework can simulate cloud‐scale ...

Eddy Influences on the Hadley Circulation

open access: yesJournal of Advances in Modeling Earth Systems, 2019
Variations in the width and strength of the Hadley cells are associated with many radiative, thermodynamic, and dynamical forcings. The physical mechanisms driving these responses remain unclear, in part because of the interactive nature of eddy‐mean ...
