The Effect of a Rectangular-scaffold Tower on Extinction Coefficients and Winds Measured in Close Proximity to the Tower by Donald A. Chisholm,Joseph J. Pazniokas Pdf
An examination of observations of extinction coefficients and winds gathered on opposite sides of a rectangular scaffold tower was conducted to determine to what extent the tower structure altered the prevailing characteristics of the atmospheric parameters. Data were gathered over a two-month period during a wide range of conditions (rain, stratus and fog, and unrestricted periods of visibility) and measurements of the variability of the observations were determined. From these studies, it was found that: (1) The tower structure does not adversely affect the prevailing homogeneity of extinction coefficient, (2) wind speed is retarded by about 10% on the lee side of the tower, and (3) wind direction is more variable on the windward side of the tower.
