Regime of Validity of Soundproof Atmospheric Flow Models
Publisher: American Meteorological Society
Abstract: Ogura and Phillips derived the original anelastic model through systematic formal asymptotics using the flow Mach number as the expansion parameter. To arrive at a reduced model that would simultaneously represent internal ...
Drag Parameter Estimation Using Gradients and Hessian from a Polynomial Chaos Model Surrogate
Publisher: American Meteorological Society
Abstract: variational inverse problem is solved using polynomial chaos expansions to infer several critical variables in the Hybrid Coordinate Ocean Model?s (HYCOM?s) wind drag parameterization. This alternative to the Bayesian ...
Polynomial Chaos–Based Bayesian Inference of K-Profile Parameterization in a General Circulation Model of the Tropical Pacific
Publisher: American Meteorological Society
Abstract: he authors present a polynomial chaos (PC)?based Bayesian inference method for quantifying the uncertainties of the K-profile parameterization (KPP) within the MIT general circulation model (MITgcm) of the tropical Pacific. ...
Uncertainty Propagation in Coupled Atmosphere–Wave–Ocean Prediction System: A Study of Hurricane Earl (2010)
Publisher: American Meteorological Society
Abstract: This study focuses on understanding the evolution of Hurricane Earl (2010) with respect to random perturbations in the storm?s initial strength, size, and asymmetry in wind distribution. We rely on the Unified Wave ...
Bayesian Inference of Drag Parameters Using AXBT Data from Typhoon Fanapi
Publisher: American Meteorological Society
Abstract: he authors introduce a three-parameter characterization of the wind speed dependence of the drag coefficient and apply a Bayesian formalism to infer values for these parameters from airborne expendable bathythermograph ...
