1. Avaliação da Habilidade do Modelo WRF em Representar a Precipitação na Amazônia Usando Diferentes Escalas
Resumo A precipitação no norte da Amazônia dos verões e outonos austral, do período de 1988 a 1999, foi simulada utilizando o modelo regional Weather Research and Forecasting (WRF), através de uma abordagem em escalas distintas, com domínios aninhados de 45 e 15 km. As condições iniciais e de contorno foram obtidas da Climate Forecast System Reanaly

2. Global patterns of aboveground carbon stock and sequestration in mangroves
ABSTRACT In order to contribute to understand the factors that control the provisioning of the ecosystem service of carbon storage by mangroves, data on carbon stock and sequestration in the aboveground biomass (AGB) from 73 articles were averaged and tested for the dependence on latitude, climatic parameters, physiographic types and age. Global means of car

3. Verificação da previsão do tempo em São Paulo com o modelo operacional WRF / Review of weather in São Paulo with the WRF Operational Model.
Forecasts of daily maximum and minimum temperatures and rainfall performed by the operational numerical weather prediction WRF (Weather Research Forecasting) model in the São Paulo are evaluated. Initial and boundary conditions provided by the 00UTC Global Forecast System (GFS) Model and WRF run for 72 hours, with two nested grids (with horizontal grid spac

4. Ocorrência de ventos fortes no estado do Paraná : gênese e impactos
The knowledge of climatic conditions is essential to socioeconomic activities, especially for agricultural and urban planning. Thus has the objective of this work to present a study of winds in the state of Paraná, which was established by calculating and analyzing daily, monthly and yearly mean wind speed, relative frequency, distribution of the accumulate

5. Verificación de los pronosticos del modelo BRAMS centrado en la region subtropical de Sudamerica
The aim of this work is to verify the forecasts generated in the Department of Atmospheric Sciences and Ocean, University of Buenos Aires with the Brazilian model Regional Atmospheric Modeling System (BRAMS). Since year 2006, every day two different forecasts that extend for 72 hours have been performed using two nested grids with an horizontal resolution of

6. 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

7. Contribuição do aninhamento do modelo Eta no modelo de circulação geral atmosférico e acoplado oceano-atmosfera do CPTEC na previsão do clima de verão sobre a América do Sul e Atlântico Tropical / Contribution of nesting regional eta model in atmospheric and coupled ocean-atmosphere general circulation model in seasonal forecast over South America and Tropical Atlantic
This work aims to verify the advantage of nesting Eta model in global coupled ocean-atmosphere model (CGCM) in climate forecast over South America and Tropical Atlantic. Three ensembles hindcasts of ten summer (December, January and February) between 1997 and 2006. The hindcasts consist of two global models from CPTEC, one atmospheric (AGCM;T062L28) and anot

8. Impacto da assimilação de dados de precipitação no sistema RPSAS/CPTEC: um estudo de caso de complexo convectivo de mesoescala / Impact of precipitation assimilation in CPTEC s RPSAS system: a case study of mesoscale convective system
This work presents the results of a impact study of estimated precipitation data assimilation in RPSAS from CPTEC, during January 2003. In this study, the precipitation assimilation was performed during the generation of first guess by the regional Eta model using a methodology similar to nudging. From this first guess, the RPSAS system generates an analysis

9. FOREST FIRES IN MOUNTAIN NATIONAL PARK OF ITABAIANA - SERGIPE. / INCÊNDIOS FLORESTAIS NO PARQUE NACIONAL SERRA DE ITABAIANA SERGIPE.
This research was developed with the objective to determine the forest fire danger index that is the most efficient to predict forest fire inside the National Park Serra de Itabaiana. It also simulates the characteristics of the fire inside each type of vegetation, in order to characterize the risk in each situation. To simulate the forest fires, was used th

10. Subsídios à operação de reservatórios baseada na previsão de variáveis hidrológicas
Diversas atividades humanas são fortemente dependentes do clima e da sua variabilidade, especialmente aquelas relacionadas ao uso da água. A operação integrada de reservatórios com múltiplos usos requer uma série de decisões que definem quanta água deve ser alocada, ao longo do tempo para cada um dos usos, e quais os volumes dos reservatórios a ser

12. Previsão de longo prazo da umidade do solo na bacia do rio Uruguai
Soil moisture is a very important variable in the interaction soil-atmosphere, contributing in hydrological processes and in agriculture. Determining this variable is an essential data for planning farming activities, and also when choosing the most adequate type of culture depending on the climate of the region. Water storage in the soil is also important f
