AbstractFuture offshore wind farms around the world will be built with wind turbines of size and capacity never seen before (with diameter and hub height exceeding 150 and 100 m, respectively, and rated power exceeding 10 MW). Their potential impacts at the surface have not yet been studied. Here we conduct high-resolution numerical simulations using a mesoscale model with a wind farm parameterization and compare scenarios with and without offshore wind farms equipped with these 'extreme-scale' wind turbines. Wind speed, turbulence, friction velocity, and sensible heat fluxes are slightly reduced at the surface, like with conventional wind turbines. But, while the warming found below the rotor in stable atmospheric conditions extends to the surface with conventional wind turbines, with extreme-scale ones it does not reach the surface, where instead minimal cooling is found. Overall, the surface meteorological impacts of large offshore wind farms equipped with extreme-scale turbines are statistically significant but negligible in magnitude.en_US
SponsorPartial funding for this research came from the University of Delaware (UD) Graduate College Doctoral Fellowship and from the Delaware Natural Resources and Environmental Control (DNREC, Award No. 18A00378), and UD School of Marine Science and Policy graduate fellowship. The simulations were conducted on the UD Caviness, and NCAR Cheyenne high-performance computer clusters.en_US
