RISDetecting the Nonstationary Response of ENSO to Greenhouse Warming
Publisher: American Meteorological Society
Abstract: On the basis of the latest greenhouse warming experiment performed with the Max-Planck Institut coupled atmosphere/isopycnal ocean model (ECHAM4/OPYC) it is shown that not only the climate mean but also the statistics of ...
Tropical Air–Sea Interactions Accelerate the Recovery of the Atlantic Meridional Overturning Circulation after a Major Shutdown
Publisher: American Meteorological Society
Abstract: Using a coupled ocean?sea ice?atmosphere model of intermediate complexity, the authors study the influence of air?sea interactions on the stability of the Atlantic Meridional Overturning Circulation (AMOC). Mimicking glacial ...
Empirical Dynamical System Modeling of ENSO Using Nonlinear Inverse Techniques
Publisher: American Meteorological Society
Abstract: A statistical technique is presented that allows for the empirical derivation of dynamical system equations from data. It is based on multiple nonparametric regression analysis and is applicable to a broad class of physical ...
Northern Hemispheric Interdecadal Variability: A Coupled Air–Sea Mode
Publisher: American Meteorological Society
Abstract: A coupled air?sea mode in the Northern Hemisphere with a period of about 35 years is described. The mode was derived from a multicentury integration with a coupled ocean?atmosphere general circulation model and involves ...
Northern Hemispheric Interdecadal Variability: A Coupled Air–Sea Mode
Publisher: American Meteorological Society
Abstract: A coupled air?sea mode in the Northern Hemisphere with a period of about 35 years is described. The mode was derived from a multicentury integration with a coupled ocean?atmosphere general circulation model and involves ...
ENSO Suppression due to Weakening of the North Atlantic Thermohaline Circulation
Publisher: American Meteorological Society
Abstract: Changes of the North Atlantic thermohaline circulation (THC) excite wave patterns that readjust the thermocline globally. This paper examines the impact of a freshwater-induced THC shutdown on the depth of the Pacific ...
An Initial Intercomparison of Atmospheric and Oceanic Climatology for the ICE-5G and ICE-4G Models of LGM Paleotopography
Publisher: American Meteorological Society
Abstract: This paper investigates the impact of the new ICE-5G paleotopography dataset for Last Glacial Maximum (LGM) conditions on a coupled model simulation of the thermal and dynamical state of the glacial atmosphere and on both ...
Interannual to Decadal Predictability in a Coupled Ocean–Atmosphere General Circulation Model
Publisher: American Meteorological Society
Abstract: The predictability of the coupled ocean?atmosphere climate system on interannual to decadal timescales has been studied by means of ensemble forecast experiments with a global coupled ocean?atmosphere general circulation ...
The Effect of Orbital Forcing on the Mean Climate and Variability of the Tropical Pacific
Publisher: American Meteorological Society
Abstract: Using a coupled general circulation model, the responses of the climate mean state, the annual cycle, and the El Niño?Southern Oscillation (ENSO) phenomenon to orbital changes are studied. The authors analyze a 1650-yr-long ...
The Influence of a Weakening of the Atlantic Meridional Overturning Circulation on ENSO
Publisher: American Meteorological Society
Abstract: The influences of a substantial weakening of the Atlantic meridional overturning circulation (AMOC) on the tropical Pacific climate mean state, the annual cycle, and ENSO variability are studied using five different coupled ...
