Abstract: inear mountain gravity waves forced by a nonlinear surface boundary condition are derived for a background wind that is null at the surface and increases smoothly to reach a constant value aloft and for a constant buoyancy ...

Abstract: The backward reflection of a stationary gravity wave (GW) propagating toward the ground is examined in the linear viscous case and for large Reynolds numbers (Re). In this case, the stationary GW presents a critical level ...

Abstract: The author uses an approximation of the extended Kalman filter to estimate the forecast and analysis error covariances of an operational assimilation system. The fundamental differences with Kalman filtering are the ...

Abstract: The problem of the representation of the orientation of mountain forces in a GCM is examined. First a series of winter simulations is presented with the Laboratoire de Météorologie Dynamique GCM where the model ground is ...

Abstract: The ability of long-wave low-frequency basin modes to be resonantly excited depends on the efficiency with which energy fluxed onto the western boundary can be transmitted back to the eastern boundary. This efficiency is ...

Abstract: The theory of first-passage time distribution functions and its extension to last-passage time distribution functions are applied to the problem of tracking the movement of water masses to and from the surface mixed layer ...

Abstract: A two-dimensional rotating anelastic model is used to analyze the large-scale flow (LSF) response to the breaking of gravity waves (GWs) at critical levels. In the response the balanced part is separated from the inertial ...

Abstract: Piezoelectric dynamometers are widely used for cutting force measurements. Indeed, this device has the largest bandwidth for this kind of measurement. Nevertheless, the behavior of this device ...

Abstract: The alkali-silica reaction (ASR) is a chemical reaction that causes expansions and unexpected deformations of concrete structures. A methodology of assessment of ASR-damaged structures is required in order to evaluate their ...
