The meteorological model RAMS at Crati Scrl

摘要

At Crati Scrl an operational version of RAMS 4.3 (Regional AtmosphericModeling System) was implemented in January 2001. This paper aims to give afirst assessment of model performances for quantitative precipitationforecast (QPF). In essence, the effects of enhanced horizontal gridresolution over Calabria, using a 6km spacing domain nested in a 30kmresolution parent grid, is studied.

To cope with this problem two integrations sets are discussed using twomodel resolutions. Integrations are performed daily for six months. ECMWF12:00UTC forecast cycle is used for initial and dynamic boundaryconditions.

Performances are evaluated by scores computed from model outputs andraingauge measurements coming from Calabrian regional network.
