1. Suitable weather condition frequency for fungicide soybean application in Tangará da Serra, Mato Grosso, Brazil
ABSTRACT The aim of this study was to model the decendial and hourly variability of meteorological variables, namely air temperature, relative air humidity and wind speed, in the Tangará da Serra region, Mato Grosso, Brazil, to determine the best schedules for fungicide applications to soybean crops. Hourly weather data between 2004 and 2017 from the Tangar

4. Wet Days in the Dry Quarter of the Alcântara Launch Center Region: Observational Features
ABSTRACT: Precipitation events are infrequent in the dry quarter (SON) of the Alcântara Launch Center (Centro de Lançamento de Alcântara, CLA), the main launch site of the Brazilian Space Program. However, their occurrence could be a risk for activities during launch missions. In this work, the observational features of wet days (daily precipitation total

5. Effects of atmospheric oscillations on infectious diseases: the case of Chagas disease in Chile
BACKGROUND Currently, there is an increasing global interest for the study of how infectious diseases could be linked to climate and weather variability. The Chagas disease was described in 1909 by Carlos Chagas, and is caused by the flagellate protozoan Trypanosoma cruzi. The Chagas disease is considered one of the biggest concerns in public health in Lat

6. Seasonal and Circadian Study of a Thymol/γ-Terpinene/p-Cymene Type Oil of Ocimum gratissimum L. and Its Antioxidant and Antifungal Effects
Ocimum gratissimum oil is used for various medicinal, food and cosmetic applications due to its high chemical variability. Local businesses have considered the economic exploitation of this plant. A specimen sampled at São Luís, MA, Brazil, with thymol and derivatives oil, was subjected to seasonal and circadian study, and to antifungal and antioxidant ass

7. Rainfall trends for the State of Paraná: present and future climate
Resumo O objetivo deste artigo é analisar a variabilidade e a tendência de precipitação do Estado do Paraná, Brasil. Para isso, foram analisados os dados de precipitação mensal pertencentes a 24 estações de precipitação pluviométrica em um período de 30 anos (1980-2010) e foi comparado com as projeções futuras sobre a precipitação para os an

8. 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-

9. Sensitivity of the sorghum yield to individual changes in climate parameters: modelling based approach
Based on sensitivity analyses the effect of changing in climate on sorghum has been investigated. This has been achieved by conducting crop modeling experiments carried out with weather observations and output of global climate models. As can be anticipated results demonstrated that the sorghum yield is more sensitive to rainfall, solar radiation and CO2 con

10. 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

12. 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
