A statistic, the BV (bred vector) dimension, is introduced to measure the effective local finite-time dimensionality of a spatiotemporally chaotic system. It is shown that the Earth's atmosphere often has low BV dimension, and the implications for improving weather forecasting are discussed.

Local dimension and finite time prediction in coupled map lattices
TLDR
This paper discusses the use of the bred vector (BV) dimension, a recently introduced statistics, to identify the regimes where a finite time forecast is feasible and shows the finite time predictability in two-dimensional coupled map lattices in the regions of low BV dimension. Expand
Mechanisms for the Development of Locally Low-Dimensional Atmospheric Dynamics
The complexity of atmospheric instabilities is investigated by a combination of numerical experiments and diagnostic tools that do not require the assumption of linear error dynamics. These toolsExpand
Low dimensional behavior in three-dimensional coupled map lattices
Abstract The analysis of one-, two-, and three-dimensional coupled map lattices is here developed under a statistical and dynamical perspective. We show that the three-dimensional CML exhibits lowExpand
Predictability, bred vectors, and generation of ensembles in space-time chaotic systems.
TLDR
A natural way of preparing ensembles based in using finite-amplitude perturbations with varying correlation is presented, which allows one to take into account the underlying dynamics to generate initial perturbation with spatial correlations varying from fully correlated (bred vectors) to random fluctuations.

Long-term prediction of chaotic systems with machine learning
This paper develops a machine learning scheme to obtain long term predictions on chaotic systems, including high-dimensional, spatiotemporal chaotic systems, by using extremely rare updates
Estimating the State of Large Spatio-Temporally Chaotic Systems: Application to a Rayleigh-Benard Convection Experiment
We consider the estimation of the state of a large spatio-temporally chaotic system from noisy observations and knowledge of a system model. Standard state estimation techniques using the KalmanExpand
On the prediction of linear stochastic systems with a low-order model
Three methods for approximating the high-dimensional stochastic system with a low-dimensional model are examined, and the prediction error and predictability of the reduced-order models areExpand
Bred vectors of the Lorenz63 system
The breeding method has been widely used in studies of data assimilation, predictability and instabilities. The bred vectors (BVs), which are the nonlinear difference between the control andExpand
On the Relation between Predictability and homoclinic Tangencies
TLDR
It is shown that, in both cases, regions of enhanced predictability have been found around homoclinic tangencies, and it is demonstrated that the length of these regions shrinks exponentially with increasing time of prediction. Expand
Exploiting Local Low Dimensionality of the Atmospheric Dynamics for Efficient Ensemble Kalman Filtering
TLDR
This paper shows how the finding that vectors of the forecast uncertainties in such regions tend to lie in a subspace of much lower dimension than that of the full atmospheric state vector can be exploited to formulate a potentially accurate and efficient data assimilation technique. Expand

Ten bred vectors are made available, but five of them are the result of subtracting the perturbations from the main solution; hence we average the pairs of the perturbations to give five bred vectors
