Weather forecasting digital model

Weather forecasting models are used to show atmospheric conditions by computing changes in meteorological parameters on a 3D atmospheric grid model. Physical laws are used to determine behaviour: fluid mechanics, turbulence, radiation, and atmospheric interaction with space, the continents and the oceans. The initial conditions are determined by assimilating variational data including a large volume and wide variety of in situ observations obtained from remote detection systems.

The weather forecasts available on data.shom.fr only contain "wind at 10m" and "atmospheric pressure at sea level" parameters. A land/sea mask is then applied to exclude non-maritime forecasts. These forecasts are provided by 2 different models: ARPEGE for global and european regional scale (0.25° to 0.1° resolutions, respectively) ; AROME for mainland France (1.3 km resolution) and AROME Outre-Mer for overseas areas (2.5 km resolution).

ARPEGE is a global hydrostatic spectral model, with variable horizontal resolution (centred on France), vertical finite element modelling and hybrid vertical coordinates. ARPEGE is an integral part of the Arpège-IFS software package, designed, developed and maintained by Météo-France in cooperation with ECMWF.

AROME is a non-hydrostatic spectral model for weather forecasts in mainland France, with finite difference modelling for vertical input and hybrid coordinates. AROME was developed by Météo-France thanks to close national (CNRS) and international (ECMWF, Aladin, Hirlam) cooperation programmes on the basis of the Méso-NH research model and the dynamic core of the Aladin model.

AROME Outre-Mer is a non-hydrostatic spectral model for the overseas areas (Antilles, Guyane, Réunion-Mayotte). Unlike AROME France, this regional model does not have its own assimilation. The model is forced by IFS (16km resolution, ECMWF) for initial altitude conditions and by ARPEGE for initial surface conditions. It was developed by Météo-France.

Statement

The weather model outputs on data.shom.fr provide each run with a forecast from day D to day D+2/D+4.

The weather models proposed on data.shom.fr are to be considered according to their spatial extents:

- GLOB025: wind forecasts at the global scale, based on the Météo-France ARPEGE model with a 0.25° grid.

- EURAT01: European scale forecasts, produced with ARPEGE model on a 0.1° horizontal grid.

- ANGUY025: regional Antilles-Guyane grid at 0.25° horizontal resolution, derived from a spatial subsampling of the ARPEGE GLOB025 configuration.

- MASCA025: regional indian Ocean grid at 0.25° horizontal resolution, derived from a spatial subsampling of the ARPEGE GLOB025 configuration.

- EURW1S100: forecasts for the french coasts, produced with AROME model, on a high resolution 0.01° grid.

- CARAIB0025: forecasts for the Antilles area, produced with AROME model, on a high resolution 0.025° grid.

- GUYANE0025: forecasts for the Guyane area, produced with AROME Outre-Mer model, on a high resolution 0.025° grid.

- INDIEN0025: forecasts for the Réunion-Mayotte area, produced with AROME Outre-Mer model, on a high resolution 0.025° grid.
