MATSUDO, Cynthia et al. Sistema de pronóstico experimental en alta resolución con el modelo Brams. Meteorologica [online]. 2013, vol.38, n.1, pp.53-68. ISSN 1850-468X.

This work presents the characteristics of a high-resolution numerical forecast system using the BRAMS model version 4.2 designed for the forecast of storms in the Pampa region which is processed on daily basis at the National Meteorological Service of Argentina (NMS). The forecast system is described by showing a case study and a first evaluation of its quality. In particular, the results of rainfall forecasts are presented with an operational verification scheme which implies the application of adequate methodologies for high-resolution forecasts. We discuss the availability of remote sensing data with higher spatial and temporal resolutions than the ones usually used. Finally, the results of rainfall probabilistic forecasts are shown and we examine the advantages of this tool as a value-added product giving the incorporation of the uncertainty associated to the numerical simulations of the atmosphere.

Palavras-chave : Precipitation forecast; Numerical model; High resolution.
