An unstructured CD-grid variational formulation for sea ice dynamics
Giacomo Capodaglio, Mark R. Petersen, Adrian K. Turner +1
For the numerical simulation of earth system models, Arakawa grids are largely employed. A quadrilateral mesh is assumed for their classical definition, and different types of grid…
(Un)predictability of strong El Niño events
John Guckenheimer, Axel Timmermann, Henk Dijkstra +1
The El Niño-Southern Oscillation (ENSO) is a mode of interannual variability in the coupled equatorial Pacific coupled atmosphere/ocean system. El Niño describes a state in which s…
Intrinsic unpredictability of strong El Niño events
John Guckenheimer, Andrew Roberts, Axel Timmermann +1
The El Niño-Southern Oscillation (ENSO) is a mode of interannual variability in the coupled equatorial ocean/atmosphere Pacific. El Niño describes a state in which sea surface temp…
Mixed mode oscillations of the El Niño-Southern Oscillation
Andrew Roberts, Esther Widiasih, Axel Timmermann +2
Very strong El Niño events occur sporadically every 10-20 years. The origin of this bursting behavior still remains elusive. Using a simplified 3-dimensional dynamical model of the…
Relaxation oscillations in an idealized ocean circulation model
Andrew Roberts, Raj Saha
This work is motivated by a desire to understand transitions between stable equilibria observed in Stommel's 1961 thermohaline circulation model. We adapt the model, including a fo…
Mixed mode oscillations in a conceptual climate model
Andrew Roberts, Esther Widiasih, Chris K. R. T. Jones +1
Much work has been done on relaxation oscillations and other simple oscillators in conceptual climate models. However, the oscillatory patterns in climate data are often more compl…
