RISAn Analysis of Klemp–Wilhelmson Schemes as Applied to Large-Scale Wave Modes
Publisher: American Meteorological Society
Abstract: The use of Klemp?Wilhelmson (KW) time splitting for large-scale and global modeling is assessed through a series of von Neumann accuracy and stability analyses. Two variations of the KW splitting are evaluated in particular: ...
The Impact of Noisy Physics on the Stability and Accuracy of Physics–Dynamics Coupling
Publisher: American Meteorological Society
Abstract: he coupling of the dynamical core of a numerical weather prediction model to the physical parameterizations is an important component of model design. This coupling between the physics and the dynamics is explored here ...
The Unexpected Rapid Intensification of Tropical Cyclones in Moderate Vertical Wind Shear. Part III: Outflow–Environment Interaction
Publisher: American Meteorological Society
Abstract: AbstractInteractions between the upper-level outflow of a sheared, rapidly intensifying tropical cyclone (TC) and the background environmental flow in an idealized model are presented. The most important finding is that ...
High-Altitude (0–100 km) Global Atmospheric Reanalysis System: Description and Application to the 2014 Austral Winter of the Deep Propagating Gravity Wave Experiment (DEEPWAVE)
Publisher: American Meteorological Society
Abstract: AbstractA data assimilation system (DAS) is described for global atmospheric reanalysis from 0- to 100-km altitude. We apply it to the 2014 austral winter of the Deep Propagating Gravity Wave Experiment (DEEPWAVE), an ...
