13. Caracterização física e dinâmica de episódios de chuvas intensas nas regiões sul e sudeste do Brasil / Physical and dynamical characteristics of heavy rainfall episodes in southern and southeastern Brazil
The heavy rainfall events occurred in Southern and Southeastern Brazil between 1960 and 2004 are investigated. It is observed positive trends in the annual frequency of these events in both regions in this period of 45 years. The trend in Southern Brazil is more significant. The atmospheric environments associated with these events also are investigated, but

14. Experimentos com o modelo regional eta em diferentes configurações durante o período salljex e mecanismos de mesoescala associados ao desenvolvimento de scm / Experiments with the regional eta model in different settings during the salljex period and mesoescale mechanisms associated with MCS development
The rainfall regime over southern Brazil, Uruguay and northern Argentina is strongly influenced by Mesoscale Convective Complexes (MCCs) that develop during night time associated with the Low Level Jet (LLJ) to the east of Andes. As they are mesoscale systems, their predictability depends on the model resolution and ability in representing the main features

15. Estudo fÃsico-hÃdrico em lisÃmetros e comparaÃÃo de elementos climÃticos na regiÃo de Lavras - MG / Physical-hydric study in lisymeters and comparison between climatic elements at the region of Lavras, MG,
This work aimed to compare data obtained from conventional (EMC) and automatic (EMA) meteorological stations, and to compare different methods against the standard method for estimating the reference evapotranspiration (ETo), for the region of Lavras, Minas Gerais, Brazil. The EMC data, between 2005 and 2008, were obtained from National Institute of Meteorol

16. EMISSÃO DE GASES DE EFEITO ESTUFA EM SISTEMAS DE MANEJO EM SOLO DO PLANALTO MÉDIO DO RIO GRANDE DO SUL / SHORT-TERM GREENHOUSE GASES EMISSIONS IN SOIL MANAGEMENT SYSTEMS IN OXISOL OF SOUTHERN BRAZIL
Agriculture is directly linked to atmospheric concentration of greenhouse gases (GHG) through basic processes that occur in the soil-plant system. Agricultural soils can act as a source or sink of GHG depending on the management practices adopted. The objective of this research was to evaluate the GHG flux in different soil management systems. This project w

17. Study of sensibility of the model BRAMS to the variations of the surface parameters in the northeast of Brazil / Estudo de sensibilidade do modelo Brams ?s varia??es dos par?metros de superf?cie do Nordeste do Brasil.
In this work a numeric experiment was accomplished with the model BRAMS (Brazilian Regional Atmospheric Modeling System) with the purpose of studying the changes in the surface variables due to the variations of the surface parameters as soil moisture and the vegetation class in the Northeast of Brazil which are input in BRAMS. They were made three simulatio

18. Recuperação de perfis de temperatura e umidade da atmosfera a partir de dados de satélite - abordagens por redes neurais artificiais e implementação em hardware / Atmospheric temperature and humidity retrieval from satellite data - artificial neural networks and hardware implementation approaches
This thesis presents Artificial Neural Networks for inverse problem solution to recover atmospheric temperature and moisture profiles from satellite data. The Artificial Neural Networks are presented as alternative methods in the solution of inverse problems in the atmospheric data retrieval, considered ill-posed problems and requiring advanced numerical tec

20. Impactos climáticos regionais da mudança de vegetação no semi-árido do nordeste brasileiro / Impacts climatics regionals of the change vegetation in the simi-arid in the northeast Brazil
In the present study the regional climatic impacts due to the vegetation changes were evaluated, through long term numerical simulations with the regional Eta/SSiB model of the CPTEC/INPE, in which modifications were included to operate in climatic mode. The work was accomplished in two phases. In Phase I, it was evaluated the climatic change of the Northeas

23. Previsão de atributos do clima e do rendimento de grãos de milho na região Centro-Sul do Brasil / Forecast of climatic features and corn grain yield in the Brazilian Center-South region
Crop forecast has become an important tool for the private and public agricultural policies to be established. Generally, crop forecast is composed by climatic forecast and the yield estimative of growth of economically interesting parts of crops. The climatic forecast can be performed through the analyses of historical series of the climatic features and of
