1. Refinamento estatístico das previsões de vento do modelo ETA aplicado ao setor eólio-elétrico brasileiro / Statistical downscaling of Eta model wind forecasts applied to wind power generation at Northeastern Brazil
A capacidade eólica instalada vem crescendo consistentemente em diversos países nos últimos anos. Devido a seu caráter altamente variável no espaço e no tempo, um dos grandes desafios impostos por esta fonte energética está em prever a potência eólica disponível em um momento futuro, de modo a otimizar o despacho de energia, aumentar a segurança

2. IMPLEMENTATION AND EVALUATION OF METODOLOGIAS TO FORECAST FOR ÃNDICES REGIONAL RAIN INDEX IN THE RAINY SEASON IN REGION SEMI-ÃRIDA OF NORDESTE OF BRAZIL / AplicaÃÃo e AvaliaÃÃo de Metodologias para PrevisÃo de Ãndices Regionais de Chuva no PerÃodo da Quadra na RegiÃo Semi-Ãrida do Nordeste.
This study presents the application and evaluation of two distinct forecast systems Seasonal Regional Rainfall Indices on the Semi-Arid Northeast of Brazil and Basins of the Cearà State Regions. In the first case a set of numerical simulations (1971-2000) obtained from system forecast based on the theory of dynamic downscaling is used as data to input in th

3. Mathematical / Statistical and Physical / Meteorological Models for Short-term Prediction of Wind Farms Output
(...)The rapid increase of the wind power penetration in the conventional grids all over the world has been requiring (from electricity companies and wind farm promoters) a special attention to the short-term prediction of wind farms output. Fomented by interest and necessity, companies and promoters are collaborating with universities and other research cen

4. Previsão e análise sobre as regiões sudeste e sul do Brasil utilizando redes neurais artificiais / Forecast and analysis of rainfall over south and southeastern Brazil using artificial neural network
This study uses an Artificial Neural Network (ANN) technique to establish a non-linear relationship between the large scale atmospheric circulation and local surface rainfall. The method involves the use of statistical downscaling applied to outputs from Eta model. In this sense, prognostic equations were developed for 18 locations using the ANN. This method
