Abstract: The possibility that the tropical Pacific coupled system linearly amplifies perturbations produced by the Madden?Julian oscillation (MJO) is explored. This requires an estimate of the low-frequency tail of the MJO. Using ...

Abstract: In this work the role that observed intraseasonal atmospheric variability may play in controlling and maintaining ENSO variability is examined. To this end, an asymptotically stable intermediate coupled model of El ...

Abstract: A common practice in the design of forecast models for ENSO is to couple ocean general circulation models to simple atmospheric models. Therefore, by construction these models (known as hybrid ENSO models) do not resolve ...
