Wind Forecasts Power up for Reliable Energy Production

Map of hourly wind speed over Saudi Arabia in June 2010 from the WRF simulated data. From just a few monitoring locations, the team was able to efficiently compute a full forecast distribution to construct maps of wind speed for all of Saudi Arabia at high spatial resolution for up to several hours ahead.

Wind Forecasts Power up for Reliable Energy Production

King Abdullah University of Science & Technology (KAUST)

Optimizing the integration of wind energy into a country's power network requires reliable forecasts of how wind speed and direction are likely to vary in time and space over the pending few hours. KAUST researchers have now developed a statistical model that provides the best forecasts yet for wind conditions acr
