  abstract = {{Surface wind is a variable of great importance in forcing marine waves
and circulations, modulating surface fluxes, etc. Surface wind defined
on numerical grids is currently used in forecast-analysis, as well as in
climatology. Gridded fields, however, suffer for systematic errors
associated with the numerical procedures adopted in computing them. In
this paper the climatology of surface wind produced by three different
numerical models in the European-Mediterranean area is analyzed. The
systematic loss of power at the smallest grid-scales appears in the
power spectrum of all the different models. Some prototype numerical
integrations show that this systematic over-smoothing is due to
numerical stabilization operators that represent the main source of the
diagnosed error; the error progression in space and time is also

  title = {{Improved mixing representation in Emanuel's convection scheme}},
  journal = {Quarterly Journal of the Royal Meteorological Society},
  year = 2004,
  month = oct,
  volume = 130,
  pages = {3207-3222},
  abstract = {{Recent empirical and modelling studies suggest that mid-tropospheric
relative humidity (RH) is an important controlling factor of deep
atmospheric convection, which appears to be underestimated in present
cumulus parametrizations. This indicates the possible presence of
shortcomings in the way that entrainment is represented in such
parametrizations. This matter was explored in the European Cloud Systems
project (EUROCS) by means of an idealized humidity experiment in which
the main controlling parameter is RH. In the latter study,
cloud-resolving model (CRM) experiments suggested that a shallow/deep
convection transition occurs when RH crosses a threshold value that
ranges from about RH = 50\% to RH = 60\%. In this paper, we seek to
increase the responsiveness of Emanuel's convection scheme to RH, and to
reproduce the threshold behaviour of the idealized humidity case, by
replacing the original uniform probability density function (PDF) for
mixing fractions by a more flexible two-parameter bell-shaped function
that allows a wider range of behaviour. The main result is that the
parameters of this PDF can be tuned to allow a regime transition to
occur near a threshold value of RH 55\%. In contrast to CRM results,
however, this transition is between two different regimes of deep
convection rather than between a shallow and deep regime. Possible ways
to obtain a shallow-to-deep transition with Emanuel's scheme are

  abstract = {{We report here new geochronological and paleomagnetic data from the
802{\plusmn}10 Ma Xiaofeng dykes in South China. Together with existing
data, these results suggest that Rodinia probably spread from the
equator to the polar region at ca. 800 Ma, followed by a rapid ca.
90{\deg} rotation around an axis near Greenland that brought the entire
supercontinent to a low-latitude position by ca. 750 Ma. We propose that
it was the initiation of a mantle superplume under the polar end of
Rodinia that triggered an episode of true polar wander (TPW) which
brought the entire supercontinent into equatorial latitudes. An
unusually extensive emerged land area at the equator increased both
atmospheric CO $_{2}$ drawdown and global albedo, which, along
with waning plume volcanism led directly to the low-latitude Sturtian
glaciation at ca. 750-720 Ma.

  abstract = {{We provide a description and evaluation of LMDz-INCA, which couples the
Laboratoire de Météorologie Dynamique general circulation
model (LMDz) and the Interaction with Chemistry and Aerosols (INCA)
model. In this first version of the model a
CH$_{4}$-NO$_{x}$-CO-O$_{3}$ chemical scheme
representative of the background chemistry of the troposphere is
considered. We derive rapid interhemispheric exchange times of 1.13-1.38
years and 0.70-0.82 years, based on surface and pressure-weighted mixing
ratios of inert tracers, respectively. The general patterns of the
nitrogen deposition are correctly reproduced by the model. However,
scavenging processes remain a major source of uncertainty in current
models, with convective precipitation playing a key role in the global
distribution of soluble species. The global and annual mean methane (7.9
years) and methylchloroform (4.6 years) chemical lifetimes suggest that
OH is too high by about 19-25\% in the model. This disagreement with
previous estimates is attributed to the missing nonmethane hydrocarbons
in this version of the model. The model simulates quite satisfactorily
the distribution and seasonal cycle of CO at most stations. At several
tropical sites and in the Northern Hemisphere during summer, the OH
overestimate leads, however, to a too intense CO chemical destruction.
LMDz-INCA reproduces fairly well the distribution of ozone throughout
most of the troposphere. A main disagreement appears in the Northern
Hemisphere upper troposphere during summer, due to a too high tropopause
in the GCM. When the GCM winds are relaxed toward assimilated
meteorology, a much higher variability is obtained for ozone in the
upper troposphere, reflecting more frequent stratospheric intrusions.
The stratospheric influx of ozone increases from 523 Tg/yr in the base
case simulation to 783 Tg/yr in the nudged version.

  title = {{Review of capabilities of multi-angle and polarization cloud measurements from POLDER}},

  year = 2004,
  month = jan,
  volume = 33,
  pages = {1080-1088},
  abstract = {{Polarization and directionality of the Earth's reflectances (POLDER) is
a multispectral imaging radiometer-polarimeter with a wide
field-of-view, a moderate spatial resolution, and a multi-angle viewing
capability. It functioned nominally aboard ADEOS1 from November 1996 to
June 1997. When the satellite passes over a target, POLDER allows to
observe it under up to 14 different viewing directions and in several
narrow spectral bands of the visible and near-infrared spectrum (443-910
nm). This new type of multi-angle instruments offers new opportunity for
deriving cloud parameters at global scale. The aim of this short
overview paper is to point out the main contributions of such an
instrument for cloud study through its original instrumental
capabilities (multidirectionality, multipolarization, and
multispectrality). This is mainly illustrated by using ADEOS 1-POLDER
derived cloud parameters which are operationally processed by CNES and
are available since the beginning of 1999.
