The mission of the University of Delaware College of Earth, Ocean, and Environment(CEOE) is to advance the knowledge, understanding, and wise use of ocean, earth, and atmospheric resources through programs of interdisciplinary research, outreach, and education in the physical, chemical, biological, geological and social sciences. The CEOE interdisciplinary emphasis and commitment to the highest scientific ideals prepares students for rewarding careers in teaching, research, and public service.
University of Delaware CEOE graduates are interested in all interaction with the planet — from legal, economic, and political aspects of conflict resolution, to understanding and applying natural science principles for the mutual benefit of humankind and the environment. CEOE alumni hold rewarding careers around the globe, as professors, schoolteachers, research scientists, ocean engineers, development geologists, resource managers, geoarcheologists, business owners, environmental statisticians, doctors, lawyers, journalists, and diplomats.
Future 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.
