Short Summary

This study refines the theoretical understanding of Hadley Cell (HC) extent by incorporating baroclinic eddy heat and momentum fluxes into the energy flux balance, demonstrating that these eddies significantly shift the HC edge.

Objective

• To explicitly establish the theoretical effect of baroclinic eddy heat and momentum fluxes on the energy flux balance within the Hadley Cell and determine how these influence its latitudinal extent.

Study Configuration

• Spatial Scale: Global or hemispheric, focusing on tropical and subtropical regions.
• Temporal Scale: Climatological or long-term.

Methodology and Data

• Models used: Idealized atmospheric model experiments.
• Data sources: Not applicable; theoretical and idealized modeling study.

Main Results

• The incorporation of baroclinic eddy heat fluxes and changes in adiabatic processes (induced by eddy momentum fluxes) into the Hadley Cell's energy flux balance leads to a shift in the latitude of the Hadley Cell edge.
• The direction and magnitude of this shift depend on whether the heat exported by baroclinic eddies increases or decreases.
• These theoretical findings were verified using a series of idealized model experiments with varying baroclinicity.

Contributions

• Extends and updates pioneering theories on the Hadley Cell (Held, Held and Hou) by explicitly integrating the theoretical impact of baroclinic eddies.
• Provides a refined theoretical framework for understanding the role of baroclinic eddies in determining the dynamics and extent of the Hadley Cell.
