13. Avaliação do novo modelo global do CPTEC/INPE na previsão numérica de tempo de fenômenos tropicais / Evaluation of the new global model of CPTEC/INPE in the numeric weather prediction of tropical phenomena
It is important the study of meteorological phenomena that affect the tropical area as the squall lines, main responsible for the precipitation for this area and the "friagens" that cause decrease of the temperature. In this work the capacity of the model was evaluated in forecasting such phenomena, using different horizontal and vertical resolutions, using

14. Microclimate characterization of the protected environment cultivated with french-beans / Caracterização do microclima de ambiente protegido cultivado com feijão-vagem
The protected environment changes the meteorological elements in its interior related to the outward environment. The french-beans culture is considered a high risk one, being so sensitive to adverse meteorological conditions. The cultivation in protected environment may become viable the production in South Region under unfavorable year period. Due to the e

15. PARÂMETROS DE IRRIGAÇÃO PARA O FEIJOEIRO EM DIFERENTES SOLOS E ÉPOCAS DE SEMEADURA NA REGIÃO CENTRAL DO RIO GRANDE DO SUL / IRRIGATION PARAMETERS FOR COMMON BEAN IN DIFFERENT SOILS AND SOWING DATES IN THE CENTRAL REGION OF RIO GRANDE DO SUL
Common bean is produced in the entire territory of Brazil and it is the staple food of many Brazilians. In spite of being cultivated in a variety of meteorological conditions, common bean is a plant sensitive to environmental stresses, mainly water stress. To appropriately provide the plant with water, it is necessary to study the climate of the region and t

17. Mudanças climáticas e a expectativa de seus impactos na cultura da cana-de-açúcar na região de Piracicaba, SP / Climate changes and their expected impacts on the sugarcane crop in the Piracicaba region, state of São Paulo, Brazil
Recent studies show increasingly higher concentrations of greenhouse effect gases in the atmosphere since the Industrial Revolution. The major responsibility for the global warming is attributed to such increase, caused by gases resulting mainly from anthropic activities like burning fossil combustibles and deforestation. Other than temperature, precipitatio

18. Dinâmica do uso dos recursos hídricos nas bacias do ribeirão Entre Ribeiros e do rio Preto, afluentes do rio Paracatu / Water resources use dynamics in watersheds of Ribeirão Entre Ribeiros and Rio Preto, tributaries of the Paracatu River
From times past, humanity confronts problems of environmental degradation. The environment, which always performed efficiently its function of filtration, today finds itself excessively overburdened by human activities: it suffers the risk of its resources exhausting, not being able in certain situations to recuperate itself and needing the help of man.

20. Determination of marine wind fields in the Campos basin from ENVISAT/ASAR images / Extração do campo de vento na Bacia de Campos, RJ, a partir de imagens ENVISAT/ASAR
The knowledge of ocean surface winds is very important for oceanographic and meteorological studies as well as for practical applications. Considering the great difficulty of installation, operation and maintenance of instrumentation for the in situ measurement of marine winds, it is of high interest the development of methodologies for obtaining this variab

21. Antropização da bacia hidrográfica do rio Miranda: alterações climáticas, recursos naturais e desenvolvimento
The present study it objectified to analyze the behavior of the meteorological parameters, identifying the climatic changes inside of the Hydrographic Basin of Miranda River and relating such changes to the deforestation taxes and its consequences for the local communities. The related changes are associates to the evolution of the deforestation modifying th

23. Study of the Climatic Variability in Homogeneous Regions of Averaged Temperatures of the air in Rio Grande do Sul / Estudo da variabilidade climática em regiões homogêneas de temperaturas médias do ar no Rio Grande do Sul
The State of Rio Grande do Sul presents different geographical and climatological characteristics in function of latitude, longitude and influence of meteorological systems. Therefore it is necessary a more detailed study about the behavior of certain meteorological variables. The averaged temperature, although being one of the less studied variable in relat

24. Modelos prognósticos da temperatura mínima média numa região homogênea do Rio Grande do Sul / Prognostics nodels of minimum mean temperatures in a homogeneous region of Rio Grande do Sul
This work aims to study the minima mean monthly temperatures behave in RS state, Brazil, in 90 years (1913 2002) of observation. The data were cllected in 40 meteorological station distributed in the state, and the faults were completed by the correlation method. On the first step, five regions were determinated by Cluster Analysis, these regions present sim
