modèle arpege meteo france
Its climate version (ARPEGE-Climate) has been developed in the 90s (Déqué et al., 1994). Les cartes des zooms sont disponibles directement lors de la mise à jour du modèle (voir la couleur des diodes). It also utilizes a temporal two time level semi-implicit semi-lagrangian scheme.

The numerical model ARPEGE is a global and spectral general circulation model. �~ ��t��#>�K It has 105 vertical levels, with the first level at 10m above the surface and an upper level at around 70km. The parametrization of resolved clouds uses a statistical representation of the saturation deficit and relies on an instantaneous adjustment between the three water phases. �S=���x)����Z>�� Its time step is of 360 seconds.The wind horizontal components, the temperature, the specific humidity of water vapour humidity, and of four types of hydrometeors (cloud droplets, ice crystals, rain and snow), and the turbulent kinetic energy constitute the atmospheric prognostic variables of the model. The horizontal resolution of the ARPEGE model is around 7.5km over France and 37km over the Antipodes. As a new version is implemented every nine months or so, the code is continuously evolving to get the best out of the supercomputers, to assimilate data from new observation systems and to improve the components of the forecast model. : 102h pour le 00Z, 72h pour le 06Z, 114h pour le 12Z, 60h pour le 18Z ARPEGE uses a set of primitive equations with a triangular spectral truncation on the horizontal, with a variable horizontal resolution, with a finite elements representation on the vertical and a “sigma-pressure” hybrid vertical coordinate. The lifespan of the ARPEGE model goes well beyond any of its predecessors, being in use for more than 23 years now, against the old record of 8 years and 7 months for the Péridot model.The initial conditions of the ARPEGE model are based on a 4 dimensional variational assimilation (4D-Var) that incorporates a very large and varied amount of conventional observations (radio sounding, airplane measurements, ground stations, ships, buoys, etc) and also from remote sensing (ATOVS, SSMI/S, AIRS, IASI, CRIS, ATMS, SEVIRI, GPS sol, GPS satellite, SATOB, diffusiomètres, etc...).ARPEGE uses a set of primitive equations with a triangular spectral truncation on the horizontal, with a variable horizontal resolution, with a finite elements representation on the vertical and a “sigma-pressure” hybrid vertical coordinate. 2 0 obj �2�"TO�)l!��P�,A����M���4��剽�}H�T� B �7�p0�0�x��d��5&R���+U��v'V���������E�VH�3��}�GD�G��= �FH%q���V3 a�""��`kka�J��T�T.5A�V��^70����%�]���_�������i˼�z(���]��azL���δ� A mass flux scheme based on a moisture convergence closure processes phenomena associated with the deep convection (transport, clouds, precipitations, etc). x��\I�#��ׯ�6 M��J)16�a������=�=��`���-�ef�����nLAU*3��}�%C%vr���>�����ܷ���&���o7�n����ǭ�.

The transport in the atmospheric boundary layer rests on a diffusion scheme whose transfer coefficients are dependent on the turbulent kinetic energy (TKE) and a mixing length, and on a mass flux shallow convection scheme.
This system, based on 35 members, seeks to understand and quantify the uncertainty inherent to weather forecasting. Grâce à cette résolution très fine du modèle, il est possible de proposer des zooms assez précis sur la France.
Ces cartes présentent les données du modèle ARPEGE 0.5° de Météo-France. /bH@�"4&ug{a.�f�wf� Info à propos du modèle :
Ocean turbulent fluxes are computed using the ECUME parametrization whose transfer coefficients have been calibrated during many field campaigns.Four daily forecasts are made at 0, 6, 12.and 18h UTC, with forecasting time of 102h, 72h, 114h and 60h respectively. stream Monthly climatology files are used to describe physiographical properties of the soil, the vegetation , ozone and aerosols.The influence of physical processes (radiation, microphysics, surface processes) and the subgrid transport (turbulence, convection, gravity waves) on the evolution of the model prognostic variables are represented by the physics parametrizations. Les données de cette carte dynamique proviennent du modèle ARPEGE de Météo-France (résolution de 10km environ). %PDF-1.4
