1. O uso de ferramentas fractais e redes complexas no estudo da variabilidade pluviomÂetrica do Nordeste do Brasil
Brazil Northeastâs climate is usually described as semi-arid, characterized by hard dry seasons intermingled by hard rainfall seasons. Some areas of Northeast present annual pluviometric measure about 400 mm in mean, while in others the annual pluviometric measure is about 2000 mm. Rain events result from interplay of several physical phenomena, most of whi

2. Numerical simulations of severe thunderstorms in the MASP / Simulações numéricas de tempestades severas na RMSP
Tempestades severas ocorrem na Região Metropolitana de São Paulo (RMSP) principalmente nos meses quentes e úmidos do ano. Nesta tese, os mecanismos de disparo da convecção profunda são estudados por meio de análises observacionais e simulações numéricas com o Advanced Regional Prediction System (ARPS). A metodologia proposta compreende o uso da par

3. Análise das características dos relâmpagos na região sudeste do Brasil / Lightning characteristics in southeastern Brazil
The first climatological studies of cloud-to-ground (CG) lightning flashes characteristics in Brazil were published at the middle of 90. However, at that time, the lightning detection network used to be composed by only a few sensors, which restricted the analyses to some specific regions. In the beginning of this decade, new studies were published using lig

4. Alguns aspectos dinâmicos e termodinâmicos de um vórtice ciclônico de altos níveis (VCAN) sobre sua região de atuação. / Some aspects dynamics and thermodynamics of a ciclonic vortex in higle levels (CVHL) over your region of exportise.
Este trabalho tem como objetivo analisar no ponto de vista dinâmico e termodinâmico, um dos vários Vórtices Ciclônicos de Altos Níveis (VCAN) que foram observados sobre o Nordeste Brasileiro do Brasil (NEB), durante o mês de janeiro, 2002. Dados de reanálises do NCEP (Componentes u e v do vento, Altura Geopotencial, Umidade Especifica, Omega (velocid

5. Parametrização multifractal em modelos de dispersão atmosférica e estudo de caso para São José dos Campos
- In a quest for an eficient method of air quality monitoring, herein a new turbulent parameterization is applied to an atmospheric pollutant dispersion model. Diferently of the classical parameterization, based on the K41 Kolmogorov s theory, the multifractal parameterization is based on non-extensive thermodynamics and includes intermittency in its equatio

6. Desenvolvimento e caracterizaÃÃo de um sistema catalÃtico Ni(5%)/γ-Al2O3 aplicado à reforma sÃca do metano
It has been shown that methane reforming with carbon dioxide has a great potential in the chemical industry being used as storage and transformation systems of clear energy due to your reversibility and endothermicity. Furthermore, this process product the best proportion in H2:CO (1:1) recommended for oxo-alcohols and fuels obtention. These fuels are known

7. Can ozone depletion and global warming interact to produce rapid climate change?
The atmosphere displays modes of variability whose structures exhibit a strong longitudinally symmetric (annular) component that extends from the surface to the stratosphere in middle and high latitudes of both hemispheres. In the past 30 years, these modes have exhibited trends that seem larger than their natural background variability, and may be related t
