1. Estimates of reference evapotranspiration in the municipality of Ariquemes (RO) using neural networks GMDH-type
RESUMO A evapotranspiração de referência é uma variável climatológica de suma importância para o dimensionamento do uso da água nos métodos de irrigação. Neste sentido, com o intuito de contribuir para o entendimento climático de Ariquemes, RO, o estudo tem como objetivo modelar o comportamento da série temporal da evapotranspiração de referê

2. SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS
Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variat

3. Análise da distribuição da freqüência mensal de precipitação para a sub-região da Nhecolândia, Pantanal, Mato Grosso do Sul, Brasil.
Durante o período 1977 a 2000, foram analisados dados diários de precipitação coletados na Estação Climatológica de Nhumirim (latitude 18o59'19.86 S, longitude 56o37'21.74 W, altitude 97 m), localizada na fazenda Nhumirim, sub-região da Nhecolândia, Pantanal, MS. Os objetivos deste trabalho foram verificar o intervalo de precipitação que ocorreu c

4. Agroclimatic zoning for the culture of citros in the agreste of Pernambuco state, Brasil / Zoneamento agroclimático para a cultura dos citros no agreste pernambucano
The objective of this work was to evaluate the agroclimatic potential and to characterize the climatic risks zoning for citros production in Agreste Pernambuco State. Climatics data inside and next to the area of study was been used. Monthly average precipitations of 100 weather station with series of data above of 20 years of registers was been used. Places

5. Measures of the interannual marine variability on southeast Brazilian bight and its relationship to the spawning areas of Brazilian sardine (Sardinella braziliensis) / Medidas da variabilidade interanual marinha sobre a plataforma continental sudeste do Brasil e sua relação com áreas de desova da sardinha-verdadeira (sardinella brasiliensis)
This work aims to investigate the relation of marine interannual variability in a region located in southern coast of Brazil, also known as the Southeast Brazilian Bight (SBB) and the spawning areas of the Brazilian sardine (Sardinella braziliensis) in SBB. SBB marine ecosystems are related to a strong influence of a coastal upwelling system. Variables used

6. Estrutura da comunidade fitoplanctônica em sistema de áreas alagáveis, na planície de inundação do rio Jucupiranguinha, Vale do Ribeira de Iguape - SP / Structure of a phytoplanktonic community in the floodplain of the river Jacupiranguinha in the region of Vale do Ribeira de Iguape in the State of Sao Paulo
This study aimed at characterizing the spatial and temporal structure of the phytoplanktonic community and relating them to climatological and hydrological variations in the floodplain of Jacupiranguinha river. The samples were taken four times in the year, once in each season, on 3 alternating days at 11 sample stations, two of which are positioned in the r

7. Evaluation of the irrigation for central pivot in the coffee (Coffea canefhora L.) crop and papaya (Carica papaya L.) crop in the municipal district of Pinheiros-ES / Avaliação da irrigação por pivô central na cultura do café (Coffea canefhora L.) e na cultura do mamoeiro (Carica papaya L.) no município de Pinheiros - ES
The objective of the present work was to evaluate the irrigation management adopted for papaya (Carica papaya L.) and coffee (Coffea canefhora L.) production in the municipal district of Pinheiros at the north of Espírito Santo. Central pivot irrigation systems are used in the area. Eight pivots cultivated with papaya and six pivots cultivated with coffee w

8. Observations of a “weekend effect” in diurnal temperature range
Using surface measurements of maximum and minimum temperatures from the Global Daily Climatological Network data set, we find evidence of a weekly cycle in diurnal temperature range (DTR) for many stations in the United States, Mexico, Japan, and China. The “weekend effect,” which we define as the average DTR for Saturday through Monday minus the average
