A diagnostic energetics scheme is developed in order to investigate the energy flows in the three-dimensional spectral domain in the atmosphere. This energetics scheme is applied to the data during the winter from December 1978 to February 1979.

This paper discusses the merits of an energetics approach to quantifying sediment transfer processes in the Bas Glacier d'Arolla proglacial zone, Valais, during the 1987 melt-season. Energy estimates, based on sediment transfer processes, range over

Les AA. étudient le bilan d'énergie des ondes de perturbations ayant évolué sur les régions africaines (de 10E à 30W et de l'équateur à 20N) entre le 23août et le 19septembre 1974. Les mesures montrent que pour l'ensemble de la région considérée

Households and their spatial-energetic practices. Searching for sustainable urban forms
This study aims to obtain more insight into the extent to which the urban form plays a role in the household's spatial-energetic practices in order to broaden our understanding of the opportunities to achieve a more sustainable future. The study
Energetics prediction of frequency-dependent suspended sand transport rates on a macrotidal beach
In this paper, simple energetics modelling is used to compare velocity moment predictions with field observations of suspended sand transport rates. Separate consideration is given to transport associated with the 3 main frequency-dependent cross
is then used to assess the validity of this energetics approach in the prediction of cross-shore suspended sand transport fluxes.
The energetic response of urban canyons to variable urban geometry is investigated using the URBAN3 numerical model. Significant inter-urban canyon energy total differences are found which are closely linked to patterns of net solar radiation
. Implications of the study with respect to the magnitude of synoptic vs. geometric sources of urban energetic variation, and microscale and mesoscale urban modelling applications are discussed.

A spectral energetics analysis of atmospheric blocking
The AA. have calculated the evolution of the spectral energetics of two cases of blocking from the winter of 1978-79. The first case occurred over the North Atlantic and the other over the North Pacific. The Atlantic block was forced
Through a numerical example the parametric investigation method is shown. The theory and the principles of an energetical world model are outlined to evaluate the optimal resource pattern of satisfying world energy demands. - (JS)
