We consider error propagation near an unstable equilibrium state (classified as an unstable focus) for spatially uncorrelated and correlated finite-amplitude...

Traditionally, the prediction skill of atmospheric models is verified through small amplitude stability analysis. The Lyapunov exponent (LE) and singular...

It is widely recognized that uncertainty in atmospheric and oceanic models can be traced back to two factors. First, in defining the state of atmosphere (or...

Reconstruction of processes and fields from noisy data is to solve a set of linear algebraic equations. Three factors affect the accuracy of reconstruction:...

How long is an ocean (or atmospheric) model valid once it has been integrated from its initial state? What is the model valid prediction period (VPP)? To...

A new concept, valid prediction period (VPP), is presented here to evaluate ocean (or atmospheric) model predictability. VPP is defined as the time period when...

The capability of the reconstruction scheme developed in Part I is demonstrated here through three practical applications. First, the nonlinear regression...

A new approach is developed to reconstruct a three-dimensional incompressible flow from noisy data in an open domain using a two-scalar (toroidal and poloidal)...
Ocean predictability skill is investigated using a Gulf of Mexico nowcast/forecast model. Power law scaling is found in the mean square error of displacement...
