Agro Fossil Free - Afgrødevindenergieksperiment (CWEX): Observationer af overfladelag, grænselag og mesoskala interaktioner med en vindmøllepark

General beskrivelse

Crop Wind Energy Experiment (CWEX) demonstrates the importance of collecting field measurements within a wind farm to facilitate basic understanding of the three-way interactions among wind energy, meteorology, and crop agriculture. The goal is to develop a basic understanding of how this land use collocation changes both the energy and crop production systems that contribute to the nation's food and energy security needs. Preliminary profile measurements of temperature and 2-m wind speed above a soybean canopy were taken at the wind farm around the A and B lines of turbines in 2009. One mast was held stationary at a distance of 3-4D upwind of the line of turbines and depending on the wind direction the other mast was moved every 20 min at intervals of 1D downstream. The experiments thus far do not provide measurements of plant growth and yield influences of turbines. CWEX-10/CWEX-11 demonstrated that turbines very likely have positive and negative effects over short periods.
