With the Zebiak-Cane model, the present study investigates the role of model errors represented by the nonlinear forcing singular vector (NFSV) in the "spring predictability barrier" (SPB) phenomenon in ENSO pre...

Negative-phase North Atlantic Oscillation(NAO) events are generally stronger than positive-phase ones, i.e., there is a phase-strength asymmetry of the NAO. In this work, we explore this asymmetry of the NAO using t...

Conditional nonlinear optimal perturbation(CNOP) is an extension of the linear singular vector technique in the nonlinear regime.It represents the initial perturbation that is subjected to a given physical constraint,...
