Abstract: A potentially optimal description of the evolution of a simple model atmosphere is investigated. The model is a two-level, quasigeostrophic, hemispheric model, formulated in spherical harmonics and truncated at T5. The ...

Abstract: The phase space structure of the attractor of a baroclinic quasigeostrophic model is analyzed in terms of mean tendencies in dominant EOF space. The dominant EOFs as well as the probability density functions in the planes ...

Abstract: The mean state and variability of deep convection in the ocean influence the North Atlantic climate. Using an ensemble experiment with a coupled atmosphere?ocean?sea ice model, it is shown that cooling and subdued warming ...

Abstract: North Atlantic decadal climate variability is studied with a coupled atmosphere?ocean?sea ice model (ECBILT). After having reached an approximate statistical equilibrium in coupled mode without applying flux corrections, ...

Abstract: The variability in the subpolar Southern Hemisphere is studied with a coupled atmosphere?ocean?sea-ice model (the ECBilt). After having reached an approximate statistical equilibrium in coupled mode without flux corrections, ...

Abstract: Three 1000-yr climate simulations with an atmospheric general circulation model (AGCM) coupled to, respectively, a slab mixed layer model, an ocean GCM, and responding to yearly repeating daily sea surface temperature (SST) ...
