We explore meridional energy transfer in the coupled atmosphere–ocean system, with a focus on the extratropics. We present various elementary scaling arguments for the partitioning of the energy transfer between atmosphere and ocean, and illustrate those arguments by numerical experimentation. The numerical experiments are designed to explore the effects of changing various properties of the ocean (its size, geometry and diapycnal diffusivity), the atmosphere (its water vapour content) and the… 

Assessing the meridional atmosphere and ocean energy transport in a varying climate

Assessing the meridional atmosphere and ocean energy transport is one of the most classical problems in climate research. The meridional energy transport plays a critical role in maintaining the

On the meridional heat transport and its partition between the atmosphere and oceans

In this thesis I study the meridional heat transport of the climate system and its partition between the atmosphere and oceans using models and data. I focus on three primary questions: (1) What is

Decomposing the meridional heat transport in the climate system

The meridional heat transport (MHT) in the climate system is investigated using a state-of-the-art coupled climate model (CESM1.0). This work decomposes the MHT and studies their physics in detail.

Effect of wind forcing on the meridional heat transport in a coupled climate model: equilibrium response

Abstract The effect of the ocean surface winds on the meridional heat transports is studied in a coupled model. Shutting down the global surface winds causes significant reductions in both

Influence of the Extratropical Ocean Circulation on the Intertropical Convergence Zone in an Idealized Coupled General Circulation Model

AbstractThe authors present coupled model simulations in which the ocean's meridional overturning circulation (MOC) sets the zonal mean location of the intertropical convergence zone (ITCZ) in the

The importance of planetary rotation period for ocean heat transport.

The significance of the response of poleward ocean heat transport to planetary rotation period is shown with a simple meridional barrier--the simplest representation of any continental configuration and strong agreement between the model results and a scale analysis of the governing equations.

Interannual Variability of the Overturning and Energy Transport in the Atmosphere and Ocean During the Late Twentieth Century with Implications for Precipitation and Sea Level

The overturning circulations in the atmosphere and ocean transport energy from the tropics to higher latitudes and thereby modulate Earth’s climate. The interannual variability in the overturning

Oceanic Overturning and Heat Transport: The Role of Background Diffusivity

The role of oceanic background diapycnal diffusion for the equilibrium climate state is investigated in the global coupled climate model CM2G. Special emphasis is put on the oceanic meridional

Local and Remote Responses of Atmospheric and Oceanic Heat Transports to Climate Forcing: Compensation versus Collaboration

We present a theoretical study on local and remote responses of atmosphere and ocean meridional heat transports (AHT and OHT, respectively) to climate forcing in a coupled energy balance model. We

An Analysis of the Hydrological Cycle and Poleward Heat Transports Simulated by Two Climate Models

Heat and Freshwater transport by the oceans and atmosphere are an integral part of the climate system, aiming to cool the Tropics and warm the Extra-Tropics. General Circulation Models (GCMs) are



Mean Climate and Variability of the Atmosphere and Ocean on an Aquaplanet

Numerical experiments are described that pertain to the climate of a coupled atmosphere–ocean–ice system in the absence of land, driven by modern-day orbital and CO2 forcing. Millennial time-scale

Explorations of Atmosphere–Ocean–Ice Climates on an Aquaplanet and Their Meridional Energy Transports

Abstract The degree to which total meridional heat transport is sensitive to the details of its atmospheric and oceanic components is explored. A coupled atmosphere, ocean, and sea ice model of an

Exchange of heat and momentum between the atmosphere and the ocean: a minimal model of decadal oscillations

Abstract A model of the large-scale interaction between the troposphere and the upper ocean, wind-driven circulation is formulated. Simplified parametrizations, built upon the conservation of global

The Partitioning of the Poleward Energy Transport between the Tropical Ocean and Atmosphere

The mass transport in the shallow, wind-driven, overturning cells in the tropical oceans is constrained to be close to the mass transport in the atmospheric Hadley cell, assuming that zonally

The Partitioning of Poleward Heat Transport between the Atmosphere and Ocean

Abstract Observations of the poleward heat transport of the earth (H) suggest that the atmosphere is the primary transporting agent poleward of 30°, that oceanic (HO) and atmospheric (HA)

Poleward Heat Transport in a Barotropic Ocean Model

Abstract A barotropic ocean circulation model coupled to a mixed-layer temperature equation is used to study the poleward heat transport by the horizontal wind-driven ocean currents. Through scaling

Transfer properties of the large‐scale eddies and the general circulation of the atmosphere

The transfer of heat and momentum by motion on the scale of cyclone waves and long waves is deduced from a knowledge of their mechanics. The law of horizontal transfer of entropy is independent of

Large-Scale Circulation and Production of Stratification: Effects of Wind, Geometry, and Diffusion

The combined effects of wind, geometry, and diffusion on the stratification and circulation of the ocean are explored by numerical and analytical methods. In particular, the production of deep

New estimates of the poleward energy transport based on atmospheric reanalyses from the National Centers for Environmental Prediction‐National Center for Atmospheric Research (NCEP‐NCAR) and the
