The availability and reliability of wind power depend largely on current and
future climate conditions, which may vary in the context of climate change. A
high resolution regional climate model (PRECIS) was used for dynamic downscaling
of the future wind speed over Ontario. The changes of wind power density and
power production were further investigated through case studies. The spatial
pattern an... hiện toàn bộ
