1. Simplified Methodology for Temperature Calculation of Operation and Photovoltaic Modules Yield in Non-Standardized Environmental Conditions
ABSTRACT This work proposes a simplified methodology to obtain the needed data to determine and investigate the variation of photovoltaic modules performance under non-standardized environmental conditions - Standard Test Conditions and Nominal Operating Cell Temperature. This methodology uses a previously developed mathematical model in association with env

2. TIME AVAILABLE FOR SPRAYING AND MECHANIZED SOWING IN THE NORTHEAST OF THE STATE OF MATO GROSSO DO SUL AND SOUTH OF GOIÁS
ABSTRACT The sizing of mechanized agricultural systems depends on the soil and climatic conditions, the crop and the work regime. The aim of this study was to determine the probabilities of time available during an agricultural year for mechanized spraying and sowing in the northeast region of the State of Mato Grosso do Sul and south of Goiás. The meteorol

3. The Long-Range Memory and the Fractal Dimension: a Case Study for Alcântara
ABSTRACT: This study aimed to analyze the time series behavior of the Southern Oscillation Index through techniques using Fast Fourier Transform, computing the autocorrelation function, and the calculation of the Hurst coefficient. The methodology of Hurst Exponent calculation uses different lags, which are computed in the time series of Southern Oscillation

4. Vulnerabilidade socioespacial relacionada a precipitações e ventos em Atibaia - SP / Sociospatial vulnerability related to precipitation and winds in Atibaia - SP
The accelerated process of urbanization of the twentieth century contributed to increase the occupation of risk areas, mainly by the low income population. This has increased their vulnerability to problems arising from atmospheric phenomena, especially in urban centers, which widened the sociospatial segregation in several municipalities. This framework is

5. MODELO DE ESTIMATIVA DA RADIAÇÃO LÍQUIDA E SUA APLICAÇÃO NA DETERMINAÇÃO DA EVAPOTRANSPIRAÇÃO POTENCIAL
This study aimed to assess and develop a physical mathematical model to estimats the net radiation. For this we used weather data collected from the meteorological station of the Department of Physics and Meteorology of the Escola Superior de Agricultura "Luis de Queiroz" - ESALQ - University of São Paulo - USP, Piracicaba, Brazil, according to the global r

6. Analise espaço-temporal das condições meteorologicas e incidencia de gripe e pneumonia no municipio de São Paulo / Temporal-spatial analysis of the relationships between meteorological data and incindence of the influenza (flu) and pneumonia in the São Paulo metropolis
Everywhere in the world, the popular culture associates the alterations in meteorological data - rain, wind, temperature, humidity - with the behavior of human health. Scientific studies have been conducted in the aim to relate the meteorology and climate to the occurrence of human diseases, specifically of the circulatory and respiratory systems. The Sao Pa

7. Assimilação de dados das estações meteorológicas automática da FUNCEME. / Assimilation of data from automatic weather stations FUNCEME.
An observed data assimilation (ODA) technique is evaluated regarding its effects on the performance of a mesoscale atmospheric model (Regional Atmospheric Modeling System, RAMS 6.0) in a weather forecast simulation for the five first days of January 2005, which represents a transitional period in the wind regime over northern Northeast Brazil (between the dr

8. Characterization and estimation of occurrence of heat waves with impact on broiler mortality / Caracterização e previsão de ondas de calor com impacto na mortalidade de frangos de corte
As broiler production increases in Brazil it appears the need of optimizing production system mainly due to the market competitiveness, and technological resources application are required for reducing losses. Productive loss decurrently from heat wave (HW) incidence is quite common in broiler rearing under tropical conditions, and the solution for this is a

9. Padrões de circulação anômala associados a episódios úmidos e secos no sul do Brasil / Anomalous circulation patterns associated with wet and dry events in southern Brazil
The characteristics of the atmospheric circulation associated with persistent wet and dry events in Southern Brazil during all seasons were studied from 1979 to 2002, using precipitation pentad data. The result shows that the dominant oscillations of rainfall variability have periods between 2 and 6 pentads. Superposition of different periods was also identi

11. Simulação da variabilidade do clima presente sobre a América do Sul utilizando um modelo climático regional / Present-day climate variability simulations over South America using a climate regional model
The purpose of this work was to evaluate the accuracy of The Hadley Centre Regional Climate Model (HadRM3P) in describing the seasonal variability of the main climatological features over South America and adjacent (surrounding) oceans by using long-term simulations (30 years, 1961-1990). The analysis was performed using seasonal averages from observed and s
