title: dphase_qbolam11: QBOLAM meteorological model (10km) run by APAT for the MAP D-PHASE project

description: Project: D-PHASE, Demonstration of Probabilistic Hydrological and Atmospheric Simulation of flood Events in the Alpine region - The Mesoscale Alpine Programme (MAP, the first WWRP Research and Development Project (RDP)) is an international research initiative devoted to the study of atmospheric and hydrological processes over mountainous terrain. It aims towards expanding our knowledge of weather and climate over complex topography, and thereby to improve current forecasting capabilities. A large-scale field phase in the Alpine region took place from 7 September to 15 November 1999. D-PHASE (Demonstration of Probabilistic Hydrological and Atmospheric Simulation of flood Events in the Alpine region) is a WWRP Forecast Demonstration Project (FDP) and aims at demonstrating some of the many achievements of MAP, in particular the ability of forecasting heavy precipitation and related flooding events in the Alpine region. The MAP FDP will address the entire forecasting chain ranging from limited-area ensemble forecasting, high-resolution atmospheric modelling(km-scale), hydrological modelling, and nowcasting to decision making by the end users, i.e., it is foreseen to set up an end-to-end forecasting system. The demonstration period of MAP D-PHASE will be 1 June to 30 November 2007.

This parallel version, called QBOLAM, is employed in an operational setting as a part of the Sistema Idro-Meteo-Mare (Hydro-Meteo-Marine System; SIMM) forecasting chain, with a 11-km grid step over a domain covering the entire Mediterranean basin. The QBOLAM11 model is forced with the QBOLAM33 forecast data, neglecting the first 12 hours (spin-up time), producing a 48-h forecast starting at 0000 UTC. The QBOLAM 33 runs are instead initialized using the 1200 UCT European Centre for Medium-Range Weather Forecasts analyses and forecasts. The SIMM modelling chain includes also a 10-km WAve model (WAM) over the Mediterranean Sea, a shallow-water version of the Princeton Ocean Model (POM) for sea elevation over the Adriatic Sea and a finite element model for sea elevation in the Venice Lagoon (VL-FEM). For DPHASE project, forecast data are provided over a subdomain (referred as DDOM) of the original domain (which covers the entire Mediterranean Basin). Forecast data will be also available on the COPS domain (referred as CDOM). Not all the meteorological fields selected for the experiment are provided, since some of these are not produced by the QBOLAM model. Grid description: Please note that the westermost longitude and the southermost latitude points refer to the sub-domain chosen for MAP DPHASE. The QBOLAM original domain covers the Mediterranean Basin.
