13. CROP COEFFICIENT REGIONALIZATION FOR IRRIGATED AGRICULTURE PLANNING IN MARANHÃO STATE -BRAZIL
ABSTRACT: Irrigated agriculture has emerged as a necessary technology to achieve greater productivity, mainly by supplying the water requirements of agricultural crops in critical periods, especially for those regions where natural rainfall is insufficient to meet these requirements. The daily water consumption of crops is strongly influenced by local weathe

14. TVDI spatiotemporal pattern of a soybean growing area in humid subtropical climate
ABSTRACT The most southern Brazilian state, Rio Grande do Sul, is characterized by high crop yield and is, currently, the third leading soybean producer in the country. Therefore, agriculture is very important to the economy of the region. Because agriculture is highly dependent on variable weather parameters, the present study aimed to test the Temperature-

15. THERMAL ENVIRONMENT OF TABLE GRAPE PACKING HOUSES IN THE SÃO FRANCISCO VALLEY
ABSTRACT The aim of this study was to characterize the thermal environment of the sorting and packing sectors of small, medium and large packing houses in the São Francisco Valley, Northeast of Brazil. Micrometeorological data were monitored every 15 minutes for 20 days during winter 2014 and summer 2015. The parameters evaluated were air temperature (°C),

16. Increasing the regional availability of the Standardized Precipitation Index: an operational approach
ABSTRACT The need to use a length of rainfall records of at least 30 years to calculate the Standardized Precipitation Index (SPI) limits its application in several Drought Early Warning Systems of developing countries. Therefore, in order to increase the number of weather stations in which the SPI may be applied, this study quantified the difference among S

17. Generation of intensity duration frequency curves and intensity temporal variability pattern of intense rainfall for Lages/SC
The objective of this work was to analyze the frequency distribution and intensity temporal variability of intense rainfall for Lages/SC from diary pluviograph data. Data on annual series of maximum rainfalls from rain gauges of the CAV-UDESC Weather Station in Lages/SC were used from 2000 to 2009. Gumbel statistic distribution was applied in order to obtain

18. New design chart for basic wind speeds in Brazil
The design charts for basic wind speeds currently in use in Brazil [1] were created in 1977, based on wind speed records from 1950 to 1974. The database covered up to 25 years of wind records obtained in 49 weather stations, totaling 919 stationyears of data. Since 1974, additional 37 years of wind records became available, but have not been incorporated in

19. 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

20. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

22. Imputação de dados pluviométricos e sua aplicação na modelagem de eventos extremos de seca agrícola / Imputation of rainfall data and its application in modeling extreme events of agricultural drought
Este trabalho relata o procedimento utilizado na obtenção de um banco de dados contínuo de precipitação diária de estações meteorológicas localizadas no Estado do Paraná. O banco de dados é composto por 484 séries históricas com dados entre janeiro de 1975 a dezembro de 2009. Para preencher os dados faltantes do banco de dados foram testados tr�

23. Padrões climáticos atuais e futuros de temperatura do ar na Região Sul do Brasil e seus impactos nos cultivos de pêssego e de nectarina em Santa Catarina / Current and future air temperature climatic patterns in the South Region of Brazil: the impacts on peach and nectarine production in Santa Catarina
Over the years, climate changes and their direct impacts were observed in different parts of the globe. The present study considers the main air temperature patterns, including their extreme values, in Southern Brazil and assesses their impacts on peach and nectarine production. The analysis is based on daily air temperatures recorded at weather stations dis

24. DEVELOPMENT OF A WEB SYSTEM FOR NUMERICAL ESTIMATE OF METEOROLOGICAL DATA FROM RIO GRANDE DO SUL / DESENVOLVIMENTO DE UM SISTEMA WEB PARA ESTIMATIVA NUMÉRICA DE DADOS METEOROLÓGICOS DO RIO GRANDE DO SUL
Climate influences a large variety of human activities and the real-time access to climatic data aims for providing information that are fundamental in several human activities, mainly for agriculture. Nowadays there are few weather stations operating, which causes a lack of information at worldwide level, in different regions. Keeping in mind that the state
