RISEquilibration of Baroclinic Meanders and Deep Eddies in a Gulf Stream–type Jet over a Sloping Bottom
Publisher: American Meteorological Society
Abstract: Spatiotemporal evolution of a small localized meander on a Gulf Stream?type baroclinically unstable jet over a topographic slope is investigated numerically using a three-dimensional, primitive equation model. An unperturbed ...
Facilitating Strongly Coupled Ocean–Atmosphere Data Assimilation with an Interface Solver
Publisher: American Meteorological Society
Abstract: n a strongly coupled data assimilation (DA), a cross-fluid covariance is specified that allows measurements from a coupled fluid (e.g., atmosphere) to directly impact analysis increments in a target fluid (e.g., ocean). ...
Coupled Ocean–Atmosphere Covariances in Global Ensemble Simulations: Impact of an Eddy-Resolving Ocean

First Application of the Local Ensemble Tangent Linear Model (LETLM) to a Realistic Model of the Global Atmosphere
Publisher: American Meteorological Society
Abstract: AbstractThe local ensemble tangent linear model (LETLM) provides an alternative method for creating the tangent linear model (TLM) and adjoint of a nonlinear model that promises to be easier to maintain and more computationally ...

Hybrid 4DVAR with a Local Ensemble Tangent Linear Model: Application to the Shallow-Water Model
Publisher: American Meteorological Society
Abstract: n ensemble-based tangent linear model (TLM) is described and tested in data assimilation experiments using a global shallow-water model (SWM). A hybrid variational data assimilation system was developed with a 4D variational ...
