Meteorology Applications for Wind Energy
July 24, 2020 from 9:00 am — 10:00 am
Zoom Webinar with Cristina Archer
Center for Research in Wind
University of Delaware, Newark, DE
Meteorology, the science of weather and climate, is one of the fundamental disciplines relevant to wind energy. In this talk, I will explore numerous applications of meteorology to wind energy, using a combination of theory, observations, numerical simulations, and analytical models. For example, during hurricanes like Katrina or Sandy, I used numerical simulations to demonstrate that large hypothetical arrays of offshore wind farms can actually weaken the hurricane and ultimately protect the coastline from damaging storm surge. Another interesting effects of large arrays of offshore wind farms is that they can reduce the precipitation received onshore during, for example, Hurricane Harvey. I also found a slight reduction in observed onshore precipitation, not related to hurricanes, near two existing offshore wind farms in the UK. Wind farms can also cause other minor near-surface effects, due to the formation of wakes downstream of the turbines, as observed during the VERTical Enhanced miXing (VERTEX) field campaign that I conducted here in Lewes, Delaware, near the UD wind turbine. Lastly, wind turbine wakes need to be accounted for in wind resource assessment, wind power forecasting, wind farm layout optimization, and real-time control to optimize the wind power production of a wind farm.
Dr. Cristina L. Archer is a professor in the College of Earth, Ocean, and Environment at the University of Delaware, where she has a joint appointment between the Physical Ocean Science and Engineering program and the Department of Geography and Spatial Sciences. She is the Associate Director of the Center for Research in Wind (CReW), which focuses on wind energy, in particular offshore, and its integration in the electric grid. She received her Ph.D. in Civil and Environmental Engineering from Stanford University in 2004. She held a post-doctoral position there in 2004-2005 and then worked as an atmospheric modeler in the air quality district of San Francisco in 2005-2007. Dr. Archer joined the Carnegie Institution for Science in 2007 as a research associate. She was an assistant professor in the Department of Geological and Environmental Sciences of the California State University Chico during 2008-2011. She joined the University of Delaware in 2011. Dr. Archer’s research interests include wind power, meteorology, air quality, climate change, and numerical modeling.
