Stochastic Subgrid-Scale Ocean Mixing: Impacts on Low-Frequency Variability
Publisher: American Meteorological Society
Abstract: AbstractIn global ocean models, the representation of small-scale, high-frequency processes considerably influences the large-scale oceanic circulation and its low-frequency variability. This study investigates the impact ...
Effects of Stochastic Ice Strength Perturbation on Arctic Finite Element Sea Ice Modeling
Publisher: American Meteorological Society
Abstract: he ice strength parameter P* is a key parameter in dynamic/thermodynamic sea ice models that cannot be measured directly. Stochastically perturbing P* in the Finite Element Sea Ice?Ocean Model (FESOM) of the Alfred Wegener ...
A Stochastic Representation of Subgrid Uncertainty for Dynamical Core Development
Publisher: American Meteorological Society
Abstract: AbstractNumerical weather prediction and climate models comprise a) a dynamical core describing resolved parts of the climate system and b) parameterizations describing unresolved components. Development of new subgrid-scale ...
Stochastic Parameterization: Toward a New View of Weather and Climate Models
Publisher: American Meteorological Society
Abstract: he last decade has seen the success of stochastic parameterizations in short-term, medium-range, and seasonal forecasts: operational weather centers now routinely use stochastic parameterization schemes to represent model ...
