ARPEGE-NH

Model

ARPEGE-NH is the non-hydrostatic version of the Météo-France operational configuration that inherits features from both the ARPEGE/IFS global model and the AROME non-hydrostatic Local Area model.

 

Grid Resolution

The ARPEGE-NH configuration uses a Gaussian reduced grid with the truncation T8000 in spectral space, that means that the corresponding horizontal grid has a 2.5km resolution. The maximum slope of the orography is 49° and the maximum altitude is 8200m.

On the vertical, ARPEGE-NH uses a terrain following a hybrid pressure-based formulation with 75 levels. The first level is at 17m above ground at sea level. The microphysical scheme uses 5 water species (rain, snow, cloud ice, cloud water, graupel).

 

Soil Initialisation, SST and Sea Ice

Soil analysis from the IFS has been used as a daily update of the soil variables.

 

Input Data

The provided atmospheric initial condition has been used (data from IFS valid for 01 Aug 2016).
