1. Salinity and stable oxygen isotope relationship in the Southwestern Atlantic: constraints to paleoclimate reconstructions
Abstract: Stable isotopes have been widely used in the literature both to discuss current ocean circulation processes, as well as to reconstitute paleoceanographic parameters. The distribution of oxygen and deuterium stable isotopes in seawater (δ18Osw and δDsw) at the Western Tropical South Atlantic border was investigated to better understand the main fr

2. Comparative study of tall building response to synoptic and non-synoptic wind action
Abstract Until the beginning of the 21st Century, the characteristics of wind for purposes of structural analysis and design, as reflected in wind codes worldwide, were based on the behavior of wind currents in the vicinity of the ground surface observed in so-called synoptic events. It was only recently recognized that the latter are not the only cause of w

3. Statistical Analysis of Spatial and Temporal Variability of Maximum Precipitation Events on the Rio Grande do Sul
Abstract: A statistical analysis of precipitation at Rio Grande do Sul State was presented in this article. The aim of this work was to identify spatial and temporal patterns of maximum precipitation, which was achieved by fitting a theoretical variogram in maximum annual rainfalls and its times of occurrence. In the literature, it was found that this patter

4. Characterization of Surface Level Wind in the Centro de Lançamento de Alcântara for Use in Rocket Structure Loading and Dispersion Studies
Abstract: We present wind data collected for ten days during the dry season in 2008 during the Murici II Campaign, which was carried out in the area of the Centro de Lançamento de Alcântara (CLA). The main goals are to better understand processes governing the wind regime in the CLA and the development of tools for analyzing the impact of wind on rocket st

5. Caracterização da influência de sistemas frontais sobre a qualidade da água do reservatório de Itumbiara, GO, utilizando dados de sensoriamento remoto e dados in situ / Characterization of frontal systems influence on water quality of Itumbiara reservoir, GO, Brazil, using remote sensing and in situ data
In addition to human activities the water quality in reservoirs is influenced by weather and climate forcings that determine spatial and temporal variations in these systems. Conventional techniques for water quality monitoring require large time and fund investments. The synoptic view of large areas and high temporal frequency remote sensing data provides a

6. Análises das características sinóticas das trajetórias dos ciclones extratropicais que atuam na América do Sul e vizinhanças / Synoptic characteristics analysis of extratropical cyclonic tracks which act in South America and its neighborhoods
Com o intuito de aprimorar o conhecimento observacional dos ciclones extratropicais que atuam no sul da América do Sul e nos oceanos adjacentes, o presente trabalho analisa as trajetórias dos mesmos utilizando o algorítimo \textit{track}, uma análise objetiva que permite uma visão mais detalhada da avaliação desses sistemas de tempo. Especificamente,

7. Análise dinâmica, termodinâmica e microfísica de uma linha de instabilidade com o radar meteorológico móvel MXPOL / Microphysical, dynamic and thermodynamic analysis of a squall line using the mobile meteorological radar MXPOL
A prefrontal squal line (LI) that reached tne metropolitan area of São Paulo on April 26 2007 was monitored and analyzed by means of of surface and upper air measurements, weather radar and satellite data. Analyses indicate a favorable synoptic environment to form and sustain the LI. In its genesis region there was relatively warm and moiture air near the s

8. Considerações filogenéticas e taxonômicas na tribo Hureae Dumort. (Euphorbioideae- Euphorbiaceae) / Phylogenetics and taxonomics considerations of the tribe Hureae (Euphorbioideae-Euphorbiaceae).
Euphorbiaceae s.s., with five subfamilies and about 6.300 tropical and subtropical species, is one of the most complex and diversified angiosperm lines. Under a phylogenetic perspective, the approaches concerning the family are scarce and restricted to the highest levels. Among the Euphorbiaceae subfamilies, Euphorbioideae is prominent since it aggregates th

9. Upper tropospheric cyclonic vortex and Brazilian Northeast jet stream in El Niño and La Niña years. / Vórtice ciclônico em altos níveis e corrente de jato do nordeste brasileiro em anos de El Niño e La Niña.
A ligação entre Vórtice Ciclônico em Altos Níveis (VCAN) e a Corrente de Jato do Nordeste Brasileiro (CJNEB), foi analisada durante 9 anos entre 1988-2000, divididos em períodos de El Niño, La Niña e Neutro. Através dos produtos de reanálise do NCEP, e imagens do satélite METEOSAT no canal infravermelho, foram observados 167 VCANs, em grande maior

10. Uso do sensoriamento remoto orbital e de superfície para o estudo do comportamento espectral do corpo de água do reservatório de Manso, MT, Brasil / Use of orbital and surface remoto sensing to the study of the spectral signature of the reservoir water Body, MT, Brazil
The monitoring of water quality of a reservoir allows for preservation of the environment as well as bringing social-economic benefits. Remote Sensing accomplishes this monitoring in a synoptic way, because it considers spatial and time scales necessary to evaluate an aquatic ecosystem. For this, a Moderate Resolution Imaging Spectroradiometer (MODIS) sensor

12. Atmospheric patterns associated with concentrations of tropospheric ozone in the metropolitan region of Sao Paulo / Padrões atmofésricos associados a concentrações de ozônio troposférico na região metropolitana de São Paulo
In the past few years, tropospheric ozone has been noticed to exceed the states environmental agency (CETESB) air quality standards more than any other air pollutant in the Sao Paulo Metropolitan Area (SPMA), Brazil. Its assumed that different atmospheric patterns are responsible for different impacts on ozone concentrations, due to already known phenomena c
