o sistema Global Wind Atlas

Abstract

Data in wind geotechnology are very useful for characterizing specific parameters for ventilation. Currently, information is being organized, customized and made available in electronic documentation about the wind. Available on the Internet, values based on overlaps of scales, which use different types of measurement, which are raised in meteorological stations, satellite images and simulations in Computational Fluid Dynamics, are used together to build automatic graphics with a high degree of precision. The work aims to explore resources for obtaining wind data that can serve as a basis for the adequacy of studies in a given environment with known coordinates to characterize winds that allow directing potential for bases of environmental comfort. To describe an exploratory method, the GWA – Global Wind Atlas system, from Danmarks Tekniske Universitet, was selected, which is also being maintained by the Group World Bank, which uses surveys and modeling processes for around 10 years. As a result, data samples were collected that formulated parameters of average speeds, frequency variation and wind directions approximation by specific point locations in modeling environments. In addition to linear graphics and rosette diagrams for specific points on the planet, color maps that encode different speeds are reproduced in the system. For the chosen area of Ladário, Mato Grosso do Sul, a Brazilian city close to Bolivia, rises along the banks of the Paraguay River and is surrounded by massifs, data were collected from two points considered to be at an altitude of 104 and 570 m , for application in the GWA system, at relative heights of 200, 150, 100, 50 and 10 m from the winds, with a thermal discomfort due to the low wind speeds caused by the orographic barriers that present a wedge formation in the Urucum mountain range and the relief of Taquaral.
