The structural organization of initially random perturbations or "errors" evolving in a barotropic tangent linear model with time-dependent basic states taken from observations, is examined for cases ...
Detecting unstable structures and controlling error growth by assimilation of standard and adaptive observations in a primitive equation ocean model

Oceanic and atmospheric prediction is based on cyclic analysis-forecast systems that assimilate new observations as they become available. In such observationally forced systems, errors amplify depend...

For any forecasting system, the ability to reliably estimate the skill of a forecast in advance (i.e., at the time the forecast is issued) is clearly desirable. In this paper the potential of ensemble...
