AROME

AROME - a high resolution limited-area numerical weather prediction model - is one of the canonical configurations of the ALADIN system ^[1] which was developped and maintained by Portugal in partnership with the National Weather Services of Europe and North of Africa, under the framework of the Consortium ALADIN ^[2], nowadays encompassed by the new Consortium ACCORD ^[3].

This model is non-hydrostatic and was built from the dynamic core of the model ALADIN and the physical parameterization package of the French research model Meso-NH.

The operational version of AROME uses the forecasts of the operational ARPEGE model as the initial and boundary conditions. AROME runs locally with 2.5 km of horizontal resolution and 60 vertical model levels, for a 48 hours forecast range, in the following domains:

• Azores: from 35.73ºN to 40.85ºN in latitude, and 24.08ºW to 33.08ºW in longitude
• Madeira: from 31ºN to 34.74ºN in latitude, and 14.8ºW to 18.98ºW in longitude
• Iberian Peninsula: from 34.01ºN to 44.79ºN in latitude, and 1.21ºW to 12.79ºW in longitude

 The figures below show the model's orography for the Azores, Madeira and the Iberian Peninsula.

Main surface parameters:

Mean sea level pressure, 2 metre temperature, 2 metre dewpoint temperature, maximum and minimum temperatures at 2 metres, surface temperature and pressure, u and v-components of the wind at 10 metres, 10 metre wind gust, cloud cover, total precipitation, snowfall and cloud water.

Upper air parameters:

Geopotential, temperature, u and v-components of the wind, vertical velocity, relative humidity and turbulent kinetic energy.
