The Effect of a Rectangular-Scaffold Tower on Extinction Coefficients and Winds Measured in Close Proximity to the Tower.

Abstract

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.
