Scientists want to put ‘speed bumps’ in hurricane alley to slow down storms

“Offshore wind farms definitely could be a potential tool to weaken hurricanes and reduce their damage,” says Cristina Archer, a professor in the University of Delaware’s College of Earth, Ocean and Environment, who conducted a recent study published in the journal Environmental Research Letters describing the impact of offshore turbines on hurricane rainfall. “And they pay for themselves, ultimately, which is why I am excited about this.”

Professor Cristina Archer, author on the study from University of Delaware, explained:
“It is well known that wind turbines reduce the winds locally and downwind. This is because the turbine converts the motions of air into the motion of the blades (and then the spinning of the generators). This transfer of momentum basically means that the air flow is left with less energy and therefore with lower winds.”
Staggered Turbines Harness the Most Wind Power

Cristina Archer of the University of Delaware and colleagues report in Geophysical Research Letters that they started with a real, working offshore wind farm – Lillgrund in Sweden – and then, using computer simulations and real weather data, hypothetically arranged the turbines to achieve the optimum results.

The University of Delaware's Cristina Archer and her Atmosphere and Energy Research Group found that staggering and spacing out turbines in an offshore wind farm can improve performance by as much as 33 percent.

Comparison of individual versus ensemble wind farm parameterizations inclusive of sub-grid wakes for the WRF model
Wind Energy2022
Wind turbine wakes can be predicted somewhat accurately with mesoscale numerical models, such as the Weather Research and Forecast (WRF) model, via a wind farm parameterization (WFP) that treats the effects of the wakes, which are sub-grid features, on power production and the environment.
Impacts of replacing coal with renewable energy sources and electrifying the transportation sector on future ozone concentrations in the U.S. under a warming climate
Atmospheric Pollution Research2022
The potential impacts of emission reduction strategies in the electric power and transportation sectors on future ozone concentrations in the U.S. are investigated. A modeling system consisting of: the Weather Research and Forecasting (WRF), the Community Earth System Model (CESM), the GEOS-Chem, and the Comprehensive Air Quality Model with Extensions (CAMx) is deployed under a climate change scenario to simulate ozone pollution changes by mid-century.
The Jensen wind farm parameterization
103rd AMS Annual Meeting2022
Wind farm power production is known to be significantly affected by turbine wakes. When mesoscale numerical models are used to predict power production, the turbine wakes cannot be resolved directly because they are sub-grid features, and therefore their effects need to be parameterized. Here we propose a new wind farm parameterization that is based on the Jensen model, a well-known analytical wake model that predicts the expansion and wind speed of an ideal wake.
Impacts of maritime shipping on air pollution along the U.S. East Coast
Atmospheric Chemistry and Physics Discussions 20232023
Air pollution is considered a leading threat to human health in the United States (U.S.) and worldwide. An important source of air pollution in coastal areas is the globally increasing maritime shipping traffic. In this study, we take a high-resolution modeling approach to investigate the impacts of ship emissions on concentrations of various atmospheric pollutants, under the meteorological conditions and emissions of the year 2018.
New insights on wind turbine wakes from large-eddy simulation: Wake contraction, dual nature, and temperature effects
Wind Energy2023
Large-eddy simulation (LES) has been adopted to study wind turbine wakes because it can capture fine-scale details of turbulent wind flows and interactions with wind turbines. Here, we use the LES version of the Weather Research and Forecasting (WRF) model with an actuator disk model to gain insights on several wake effects that have been traditionally difficult to measure.
