Wind and Wind-Power Potential at Dugway National Test Facility Phase 1. Wind Velocity Profiles.

摘要

Data collected at meteorological towers on Dugway Ranges are used in a power law relationship for wind velocity within the 8 to 48 meter layer. Analysis shows the power law relationship functioning well for moderate to high wind speeds and during daytime. Wind speed has a minor influence on actual magnitude of power law exponents, but a major influence on the scatter of exponent values, making velocity profile relationships invalid for nocturnal light wind conditions. A least squares fit is used to compute power law exponents for moderate to strong wind speeds, while low wind speed cases are described only with mean values. The breakdown of velocity profile relationships with light wind is not a serious deficiency, as low wind speeds contribute little to wind power potential. (Author)
