Logit--Koopman coordinates for scale-resolved forecast-error growth in a three-level Lorenz-96 system
Malaquias Peña
Forecast-error growth in multiscale chaotic systems involves both advancement toward saturation and evolution of the error's scale distribution. We introduce Logit--Koopman coordin…

When is logistic error growth a spectral reduction?
Malaquias Peña
Forecast-error growth has been studied through complementary approaches: scalar models describe the evolution of bulk error, whereas spectral theories follow decorrelation and erro…
