| Resumo: | With the growing increase in investments in wind energy, research has been carried
out in several places to analyze how this energy source can be affected by climate
change. Thus, the general objective of this work was to evaluate the potential impact
of climate change on wind energy resources in South America, through the latest
CMIP6 future climate projections, obtaining differences between past, present and
future scenarios of wind energy density. The research was carried out using data from
the Climate Model Intercomparison Project (CMIP6) of monthly surface wind, in
which they were used, and obtained from the website of the “Earth System Grid
Federation (ESGF)” for 5 General Circulation Models of the Atmosphere (MCGA)
with horizontal resolutions equal to or less than 1.25° in latitude and longitude and
with data for future climate scenarios, SSP1-2.6 and SSP5-8.5. All the models' wind
data grids were remapped to a common grid following an área-weighted bilinear
interpolation, the data were extrapolated to the height of 100 meters by the wind
energy law and from them the wind density was calculated. Data validation was
performed using the ECMWF ERA5 reanalysis (C3S) which were compared with the
CMIP6 ensemble. Wind energy density was assessed by analyzing the differences
between the baseline (1979–2005) and future periods (2046-2072 and 2073-2099). In
general, the results showed the same baseline wind density pattern for future scenarios
with increases, mainly in scenario 8.5. The greatest variations in the future averages
in relation to the historical ones were projected in the East of the Northeast, followed
by the North of the Northeast of Brazil and Patagonia-South of Argentina, it is also
emphasized that this variation is of growth in the averages. |
