abstract = {{The régime flows corresponding to the barotropic nondivergent
equation with forcing, drag and subgrid-scale dissipation are studied
using spectral model on the plane and on the sphere. The flow
régimes obtained exhibit clear evidence of the existence of an
enstrophy-cascading inertial range, together with a reverse energy
cascade toward small wavenumbers. It is shown, however, that the
enstrophy cascade is not associated with the k$^{3}$ spectral
slope expected from the Kolmogorov-Kraichnan theory of two-dimensional
turbulence; the slopes obtained are significantly steeper. This apparent
paradox is tentatively resolved by a phenomenological theory of
space-time intermittency in two dimensions; it is further shown that
such intermittency associated with steeper spectra also restores
locality of the nonlinear transfers in wavenumber space. In contrast to
the well-known nonlocality typical of two-dimensional non-intermittent
turbulent flows. The effect of differential rotation in connection with
Rossby wave propagation is also studied: the reverse energy cascade is
actually inhibited, and zonal anisotropy prevails in the large scales as
expected from Rhines' theory. But it is shown that this anisotropy is in
fact carried down by nonlinearity throughout the enstrophy inertial
range. Finally, the predictability properties of our flows are
investigated with reference to the Leith-Kraichnan theory. It is shown
that the presence of Rossby waves actually increases predictability
through several mechanisms: direct inhibition of the nonlinear transfers
in the larger scales, concentration of energy in highly predictably
large-scale zonal structures, and slowdown of error propagation in the
enstrophy inertial range due to the presence of anisotropy at small and
intermediate scales.

abstract = {{The problem of defining turbulent diffusion for numerical modelling of
two-dimensional flows is considered. Numerical models, limited to a
finite number of degrees of freedom, do not represent interactions
between explicit scales and scales too small to be resolved, which play
an essential role in cascade processes. These interactions must be
modelled as turbulent diffusion operators in addition to the explicit
interactions. The proposed model resembles prediction-correction methods
used in numerical analysis and amounts to calculating vortex advection
with a priori small scale vortex modification as a function of vortex
movement in the neighborhood of the point considered.

abstract = {{The land surface processes as parameterized for the current version of
the L.M.D. General Circulation Model are described. The model predicts
ground temperature for bare soil, ice and snow; the treatment of ground
hydrology involves a prediction of soil moisture and snow depth. The
parameterization is tested on a 90-day integration using a sectorial
model with artificial modelling of continents and orography; sea surface
temperature, surface albedo and ice cover are given assigned values
based on climatological data for January. The resulting distributions of
hydrological and thermodynamic variables at the Earth's surface are
discussed.

abstract = {{The purpose of this study is to test a modification of the
parameterization of convection in a general circulation model. The
analysis is done with a sectorial model. Its resolution is 11 levels and
16{\middot}25 grid points. In version A of the model, we use a moist
convective adjustment (M.C.A.) wherever the air is conditionally
unstable and saturated; in version B, we add a convective scheme to
M.C.A. in the case of conditionally unstable but not saturated air. This
last scheme is based on the parameterization of Kuo (1965). We compare
zonal means and energy cycles of the two versions; improvements in
version B seem substantial, essentially in latitude-height distribution
of energy variables.
