1. Assimilação de dados com redes neurais artificiais em modelo de circulação geral da atmosfera / Data assimilation with artificial neural networks in atmospheric general circulation model
Weather forecasting systems require a model for the time evolution and an estimate of the current state of the system. The numerical weather prediction (NWP) incorporates the equations of atmospheric dynamics with physical process and it can predict the future state of the atmosphere. Data assimilation provides such an initial estimate of the atmosphere wher

2. Estudo das características das perturbações EOF extratropicais e seu impacto na previsão de tempo de médio prazo por conjunto
- The characteristics of the extratropical EOF perturbations are studied and their impact on the medium range ensemble weather prediction is evaluated, using simulations with the Center for Weather Prediction and Climate Studies Ensemble Weather Prediction System (CPTEC-EPS). The EOF method, originally applied over tropical regions and for horizontal wind an
