Abstract : A study of wind interference around an open faced tower having a triangular cross-section 6 feet on each side is presented. This includes the actual collection and analysis of wind speed and direction data around a section of a city of Austin streetlighting (moonlight) tower. Ten sets of Gill microvanes and 3-cup anemometers were employed in the study. The data were analyzed to detect changes in the mean and standard deviation of wind speed and direction observations taken simultaneously at points 3, 6, and 72 feet from the tower section. Although some interference appears to have occurred within 6 feet of the tower, it was not found statistically significant at the 95 percent confidence level. Recommendations concerning placement of wind instruments on Austin's moonlight towers are also made. (Author)
