Climate Variability
The rudiments of the way in which dynamical systems theory is starting to provide an understanding of this vast range of variability are outlined, including how interdecadal oscillations in the ocean’s circulation arise by Hopf bifurcation.
Nonlinear Physical Oceanography: A Dynamical Systems Approach to the Large Scale Ocean Circulation and El Niño,
In this book, the methodology of dynamical systems theory is applied to investigate the physics of the global ocean circulation. Topics include the dynamics of the Gulf Stream in the Atlantic Ocean,
Impact of Interbasin Exchange on the Atlantic Overturning Circulation
Abstract The thermohaline exchange between the Atlantic and the Southern Ocean is analyzed, using a dataset based on WOCE hydrographic data. It is shown that the salt and heat transports brought
Western Europe is warming much faster than expected
Abstract. The warming trend of the last decades is now so strong that it is discernible in local temperature observations. This opens the possibility to compare the trend to the warming predicted by
The mid‐Cretaceous North Atlantic nutrient trap: Black shales and OAEs
Organic-rich sediments are the salient marine sedimentation product in the mid-Cretaceous of the ocean basins formed in the Mesozoic. Oceanic anoxic events (OAEs) are discrete and particularly
Instability of the Thermohaline Ocean Circulation on Interdecadal Timescales
The stability of three-dimensional thermally driven ocean flows in a single hemispheric sector basin is investigated using techniques of numerical bifurcation theory. Under restoring conditions for
Ice‐core data evidence for a prominent near 20 year time‐scale of the Atlantic Multidecadal Oscillation
Using five ice core data sets combined into a single time series, we provide for the first time strong observational evidence for two distinct time scales of Arctic temperature fluctuation that are
When can we expect extremely high surface temperatures?
In the Essence project a 17‐member ensemble simulation of climate change in response to the SRES A1b scenario has been carried out using the ECHAM5/MPI‐OM climate model. The relatively large size of
Making sense of palaeoclimate sensitivity
This work presents a stricter approach to improve intercomparison of palaeoclimate sensitivity estimates in a manner compatible with equilibrium projections for future climate change, and reveals a climate sensitivity over the past 65 million years of 0.3–1.9 at 95% or 68% probability.
An Indicator of the Multiple Equilibria Regime of the Atlantic Meridional Overturning Circulation
Recent model results have suggested that there may be a scalar indicator Σ monitoring whether the Atlantic meridional overturning circulation (MOC) is in a multiple equilibrium regime. The quantity Σ
