RISAdaptive Mesh Refinement for Finite-Difference Ocean Models: First Experiments
Publisher: American Meteorological Society
Abstract: The application of an adaptive mesh refinement (AMR) method for structured mesh is examined in the context of ocean modeling. This method can be used with existing finite-difference ocean models at little computational and ...
A Consistent Hybrid Variational-Smoothing Data Assimilation Method: Application to a Simple Shallow-Water Model of the Turbulent Midlatitude Ocean
Publisher: American Meteorological Society
Abstract: n the standard four-dimensional variational data assimilation (4D-Var) algorithm the background error covariance matrix remains static over time. It may therefore be unable to correctly take into account the information ...
Physics–Dynamics Coupling in Weather, Climate, and Earth System Models: Challenges and Recent Progress
Publisher: American Meteorological Society
Abstract: AbstractNumerical weather, climate, or Earth system models involve the coupling of components. At a broad level, these components can be classified as the resolved fluid dynamics, unresolved fluid dynamical aspects (i.e., ...
