Abstract: The problem of resonance and meridional confinement of planetary-scale waves is investigated in the framework of a quasigeostrophic, two-layer, ?-plane model with lateral sponge layers. It is shown that the model resonant ...

Abstract: In this paper we suggest that the longevity of the enhanced predictability periods often observed in the weather and general circulation models can he quantified by a study of the statistical moments of error growth rates ...
