1. Impacto da assimilação de dados de precipitação no sistema RPSAS/CPTEC: um estudo de caso de complexo convectivo de mesoescala / Impact of precipitation assimilation in CPTEC s RPSAS system: a case study of mesoscale convective system
This work presents the results of a impact study of estimated precipitation data assimilation in RPSAS from CPTEC, during January 2003. In this study, the precipitation assimilation was performed during the generation of first guess by the regional Eta model using a methodology similar to nudging. From this first guess, the RPSAS system generates an analysis

3. Precipitation forecast aided by weather radar for early warning system of urban floods / Previsão de chuva com auxílio de radar de tempo visando a um sistema de alerta antecipado de cheias em áreas urbanas
To reduce human and material losses during floods it is feasible to concisely study the rainfall forecast as the main part of an early warning system. The use of weather radar information, when linked to physically-based forecast models, can contribute for monitoring and forecasting of intense rainfall episodes. Thus, the rainfall forecast, based on using of
