Abstract: Transition of weather regimes is examined in a highly simplified model. Two completely distinct internal methods of transition are identified. The first is a synoptically triggered large-scale instability, while the second ...

Abstract: An objective break criterion is utilized to investigate the manner in which the slowly varying component of the atmosphere ( 10-90 day frequency band) actually varies. It is found that a great deal of the behavior appears ...

Abstract: Systematically recurrent, geographically fixed weather regimes forced by a single isolated mountain in a two-layer, high-resolution, quasigeostrophic model modified for the sphere are found to be robust phenomena. While ...

Abstract: he surface of the world?s oceans has been warming since the beginning of industrialization. In addition to this, multidecadal sea surface temperature (SST) variations of internal origin exist. Evidence suggests that the ...

Abstract: We present a model intercomparison project, LongRunMIP, the first collection of millennial-length (1,000+ years) simulations of complex coupled climate models with a representation of ocean, atmosphere, sea ice, and land ...
