Abstract

On Agribusiness, it is necessary to the management of arable areas, whether in agriculture, livestock, logistics or in other segments, and that requiring the taking of important decisions, in which, for its implementation, it is necessary to know the behavior of the weather for the next day and for this, we use forecast sites. Thus, the objective of this work was to get weather forecast sites (precipitation, maximum air temperature and minimum air temperature), and confront them with real occurred for the municipality of Dom Pedrito, in Rio Grande do Sul State. For this data was collected on a daily basis, in five atmospheric weather sites on the forecast provided to the next day during a period of four months, from February to may 2016 and confronted with the actual dates in Dom Pedrito Farm’s Association Weather Station. As evaluation criteria stipulated that data would be evaluated the information for the variables, precipitation, maximum temperature and minimum temperature. After the data were tabulated in spreadsheets and performed a descriptive statistics of the data. It was observed that the overall average of hits between the sites was 67.24% forecast for the variable precipitation, 34.94% for maximum air temperature, 41.12% and minimum air temperature. However, there is a need to analyze a data series for a longer period of evaluation so that they can be trusted, as well as data provided to analyze a large number of weather stations for the studied variables.
