Abstract: It is shown from observations that the nocturnal boundary-layer depth h varies much more from night to night than within particular nights. Consequences for the parameterization and modelling of h are then examined.

Abstract: Preliminary results from the 1985 IAGO (Interaction Atmosphére-Glace-Océan) field programme in Adélie Land, Antarctica, allow for a detailed description of several katabatic events, especially of their vertical structure ...

Abstract: It is shown that higher-order turbulence-closure models include as particular solutions damped oscillations in the statically stable case, and possibly amplifying and propagating oscillations in the statically unstable ...

Abstract: Various mechanisms that can drive the evolution of the oceanic surface boundary layer (OSBL) are numerically studied using a detailed turbulence-closure scheme. It is shown that stress and shear-driven regions are characterized ...

Abstract: The HAPEX-MOBILHY program is aimed at studying the hydrological budget and evaporation flux at the scale of a GCM (general circulation model) grid square, i.e., 104 km2. Different surface and subsurface networks will be ...
