Abstract: Numerical simulation has failed to answer some fundamental questions about atmospheric frontogenesis because of the artificial minimum resolved scale in grid point and spectral models alike. To alleviate this handicap and ...

Abstract: Some fundamental properties of nongeostrophic baroclinic waves are examined by solving the equations of motion linearized about Eady's basic state at the next order of balance beyond quasi-geostrophic (QG) theory. The study ...

Abstract: The ?high drag? state of stratified flow over isolated terrain is still an impediment to theoretical and experimental estimation of topographic wave drag and mean-flow modification. Linear theory misses the transition to ...

Abstract: Under the assumption of weak background rotational and wind shear effects, an attractive computational upper boundary condition capable of transmitting gravity waves is generalized for use in a variety of f-plane models. ...

Abstract: Numerical solutions presented in a companion paper show that two-dimensional mesoscale terrain becomes a much stronger barrier to a continuously stratified flow when the flow contains warm advection. Here it is shown that ...

Abstract: The shallow atmospheric fronts that develop in the early winter along the east coast of North America have been attributed, in various modeling and observational studies, to the land?sea contrasts in both surface heating ...

Abstract: Topographic drag schemes depend on grid-scale representations of the average height, width, and orientation of the subgrid topography. Until now, these representations have been based on a combination of statistics and ...

Abstract: AbstractHigh-resolution simulation can be a powerful means of evaluating and tuning orographic drag schemes, but connecting the parameterized drag, which is a local forcing, with the model drag, which is fundamentally ...
