1. 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

2. Um estudo observacional da incursão de sistemas frontais no nordeste brasileiro e sua influência na atmosfera do Centro de Lançamento de Alcântara (CLA) / Observacional study of the incursion on frontal systems on northeast Brazil and its influence in the atmosphere of the Alcantara Launching Center (CLA)
In this work, an observational synoptic configuration pattern study was performed over the South America (SA) and in the South Atlantic (SAO) and South Pacific Oceans (SPO), in events of Frontal Systems (FSs) that reached the Brazilian northeast coast and created an intense cloudiness in the region of the Alcântara Launching Center (ALC). Seven cases were s

3. Padrões sinóticos de circulação atmosférica associados ao jato em baixos níveis a leste da Cordilheira ds Andes, na América do Sul / Atmospheric circulation patterns associated with the south america low level jet at east of the Andes
The objective of this studywas toidentify the atmospheric patterns circulationassociated with the South American Low-level Jet (LLJ). The zonal (u) and meridional (v) wind, geopotential height (f), temperature (T), specific humidity (q) and other variables from National Centers for Environmental Prediction/National Center for Atmospheric Research (NCEP/NCAR)

4. Variabilidade interdiurna da convecção na América do Sul: a propagação meridional da convecção / Day-to-day convective variability over south America: the meridional propagation of convection.
A climatology for the meridional propagation of convection (MPC) over South America (SA) for the 1983-93 years is built by using cloud and atmospheric circulation composites. Results reveal three important types of MPC over SA. Type 1 focuses the frequent penetrations of cold fronts that organize tropical convection and move with it towards equator. Type 1 i

5. Um estudo observacional da formacao e trajetorias de anticiclones extratropicais na America do Sul / An observacional study of the extratropical anticyclones in the South American continent
O presente estudo consiste em uma estatistica de onze anos de trajetorias e anticiclogeneses para os anticiclones fracos e moderados (1979 a 1989) e de trinta e oito anos (1953 a 1990) para os anticiclones intensos (cuja pressao media da trajetoria foi maior ou igual a 1030 hPa), utilizando cartas sinoticas das 12 CUT. A area estudada foi regiao continental

7. Um estudo observacional da formacao e trajetorias de anticiclones extratropicais na America do Sul / An observacional study of the extratropical anticyclones in the South American continent
In this study, South American extratropical anticyclones have been studied in the period between 1979 and 1989 for the weak and moderate ones and between 1953 and 1990 for the most intense ones (in which average pressure was greater or equal to 1030 hPa) by using daily synoptic charts. The main goal of this work was to show the tracks of the anticyclones and

8. A study of the structure of the synoptic pertubation from northeast Brazilian / Um estudo da estrutura das pertubações sinóticas do Nordeste do Brasil
An analysis of synoptic disturbances which appear in the Northeast Brazil region is presented. Three periods were selected and classified as disturbed and non-disturbed, "according to the occurrence or not .of a significant amount of rainfall. Streamlines, isotachs, and vertical velocity (omega) charts are presented for the selected periods. Vertical velocit
