Tóm tắt

AbstractChaotic nonlinear low order systems are often regarded as paradigms of the atmospheric behaviour, not least because of their limited predictability. In this paper, the predictability of a forced nonlinear system proposed by Lorenz is examined. The system is a compelling heuristic model of the mid‐latitude global circulation; it exhibits limited predictability. While weak error growth takes place throughout most of the phase space of the system, strong error growth is confined to very limited regions of phase space. A “discrete scattering” model of error growth is proposed. Copyright © 2003 Royal Meteorological Society.
